How to Protect a PDF from Copying and Printing in 2026 (6 Methods Compared)

Last updated: October 2026

TL;DR: You can restrict copying and printing inside a PDF with a permissions password: in Adobe Acrobat Pro, set Printing Allowed to None and untick Enable copying of text, images, and other content; Mac Preview, LibreOffice and PDF24 do the same for free. But those flags only hold in software that chooses to honor them. The PDF standard itself says "there is nothing inherent in PDF encryption that enforces the document permissions" (ISO 32000-1:2008, §7.6.3.1), and the qpdf manual states that qpdf "does not obey encryption restrictions already imposed on the file" (qpdf docs). To actually prevent copying and printing, don't send the file: share it view-only in a secure viewer such as Peony, which streams page images instead of the PDF, disables printing when downloads are off (on PDFs and most modern devices), blocks screenshots in supported desktop browsers on Business ($30/admin/month), and stamps each viewer's identity on every page on Data Room ($52/admin/month).

I'm Deqian Jia, co-founder of Peony, a data room company used by 8,000+ customers. People usually discover the limits of PDF restrictions the awkward way: they tick "no printing, no copying" in Acrobat, send the file, and later find the content pasted into someone else's document. The restriction did exactly what it was designed to do, which is ask the recipient's software politely. This guide covers six methods, what each one really stops, and the exact menu labels, quoted from Adobe, Apple, LibreOffice, PDF24, Google and Locklizard's own pages as of October 2026.

Quick guide: match the method to the risk

• Investor, buyer, client or board PDF you can't afford to see copied → share it view-only in Peony — Method 1
• A low-stakes PDF, and you have Acrobat Pro → permissions password — Method 2
• On a Mac without Acrobat → Preview's owner password — Method 3
• Free on Windows or Linux, or a one-off online → LibreOffice or PDF24 — Method 4
• The PDF already lives in Google Drive → Drive's download, print and copy setting — Method 5
• You sell PDFs (courses, reports, standards) to many buyers → PDF DRM — Method 6

Can you stop someone from copying or printing a PDF?

Only partly, if you send them the file. A PDF can carry permission flags that tell a reader not to print the document or let anyone copy its text, but the reader decides whether to obey them. If you keep the file and share a view of it instead, you control what reaches the recipient's device, which is the only version of "can't copy, can't print" that doesn't depend on their software.

Adobe describes two different PDF passwords, and only one of them is about copying and printing (Adobe, Password security overview):

• Document Open Password: "Requires you to enter a password to open and view the PDF, restricting access to its contents."
• Permissions Password: "Allows you to restrict certain features in the PDF, such as printing, editing, copying content, and adding comments."

Copy and print protection is the Permissions Password. A PDF with only a permissions password opens with no prompt at all, because the standard has readers first try the default (empty) user password and, if that works, "open, decrypt and display the document on the screen." From there, ISO 32000-1 is explicit: "Once the document has been opened and decrypted successfully, a conforming reader technically has access to the entire contents of the document. There is nothing inherent in PDF encryption that enforces the document permissions specified in the encryption dictionary." Conforming readers are expected to respect the creator's intent. Non-conforming ones don't have to.

So the honest framing is: a permissions password is a request to well-behaved software, and a secure viewer is control over what leaves your hands.

Why are PDF copy and print restrictions so easy to bypass?

Because the restriction lives in the file, and the person you're restricting holds the file. Four gaps follow from that:

1. The reader decides. LibreOffice's help page says "the document permission restrictions set by password will be observed only by PDF readers compliant with the version 1.5 of the format. Thus, in older PDF readers, the restrictions may have no effect," and of low-resolution printing, "Not all PDF readers honor this setting" (LibreOffice Help).
2. Tools rewrite the file without the flags. The qpdf manual: "Not all readers respect all restrictions… qpdf itself does not obey encryption restrictions already imposed on the file. Doing so would be meaningless since qpdf can be used to remove encryption from the file entirely." Free "unlock PDF" websites do the same job in a browser tab.
3. "Printing allowed" means "copy allowed." If you permit printing, even at Low Resolution (Adobe defines it as "up to 150 dpi"), a print-to-PDF driver such as Microsoft Print to PDF or the Save as PDF option on a Mac turns the print job into a new file. DRM vendors treat this as a known leak path: Locklizard lists blocking "printing to file, PDF format (Acrobat distiller and other PDF print drivers)" as a feature of its viewer.
4. The screen is always open. No permission flag touches screenshots, screen recording, or a phone camera pointed at the monitor. That needs a viewer-level control, covered in how to protect PDFs from screenshots.

None of this makes permissions useless. It makes them a speed bump for honest recipients, which is fine for a price list and wrong for a cap table.

Which methods actually protect a PDF from copying and printing?

Only the methods that keep the PDF under your control, a secure viewer or a DRM system, hold up against a determined recipient; every method that edits the file's permissions depends on the recipient's reader honoring them.

Key takeaway: Every method that works by editing the PDF (Acrobat, Preview, LibreOffice, PDF24) depends on the recipient's reader honoring the flags, so treat them as deterrence. The methods that keep the file under your control, a secure viewer like Peony or a DRM system, are the ones that hold, and of those only the secure viewer opens in any browser with no install for the recipient.

How do you share a PDF so it can't be copied or printed?

Keep the PDF on a secure platform and share a view-only link to it with downloads off (Method 1, Peony as the Secure Platform). Viewers read the document in Peony's browser viewer; Peony's docs describe it plainly: "A PDF is not sent as a PDF; it is sent as a stream of page images into the Peony viewer" (How file storage works). There is no file to save, no permissions flag for an unlock tool to strip, and no PDF text layer to select and copy.

How to set it up:

1. Upload the PDF to a Peony data room, or share it as a single file link (open the file, click Permissions, then Create link).
2. Turn downloads off. A new link has Allow downloads turned on, so switch it off in the link's settings. On the Data Room plan you can instead set just this file to View for a group in the room's Permissions table.
3. Printing goes off with it. Peony has no separate print switch; printing follows the Download level, and per the docs, with download off "on most common formats (for example PDF) and modern devices printing is disabled along with it" (Granular access control).
4. Set Screenshot protection to Basic (Business) or Advanced (Screenshield, Data Room, which extends protection to iPhone, iPad and Android with a fence view). In supported desktop browsers, native screenshot shortcuts and screen recording then produce a blurred or blank capture, and when a screenshot shortcut is detected the document area blurs and the clipboard is cleared (Screenshot protection).
5. Turn on a Dynamic watermark (Data Room) with the name, email, date, time and IP address tokens, Tiled across the page. The watermark is rendered server-side, so it can't be removed with browser devtools, and it is written onto every page of a PDF if you ever do allow a download (Dynamic watermarks).
6. Add the gates you need: a password, email verification, a link expiry, or a one-click NDA before the first page.
7. Share one link and test it in an incognito window before it goes out.

You also get page-level analytics on every plan: who opened the PDF, when, and how long they spent on each page. In a data room, if someone shouldn't see it anymore, switch their group off (or remove their email) and access ends the next time they open or refresh the link; see revoke access.

What it can't do, stated plainly. Peony's docs say printing "is only blocked where the file or device honours that," and can't be promised on every device and file format. Mobile screenshot protection reduces the capturable area rather than guaranteeing a blank capture, and a phone camera pointed at the screen always works. That is why the docs recommend keeping a dynamic watermark or an NDA on for sensitive material: a print or a photo of the screen still carries the viewer's identity. Revoking a link also doesn't reach into a file someone already downloaded, which is the reason to start with downloads off.

Tip: PDFs that already restrict editing or printing in Acrobat upload and display normally. Only a document open password should be removed before upload, because Peony itself controls who can open the file.

Pricing. Peony's Free plan ($0) shares a single PDF as a tracked link with password and email capture plus page-level analytics, but turning downloads off needs Business. Business is $30/admin/month billed annually ($44 monthly) and adds download prevention, desktop screenshot protection, email verification, a simple NDA, and 3 data rooms per admin. Data Room is $52/admin/month ($75 monthly) and adds dynamic watermarks, Screenshield for mobile, per-file permissions, signed NDAs and unlimited rooms. Viewers are free and unlimited on every plan, and Peony is SOC 2 Type II-ready and ISO 27001-ready, with both audits underway.

Best for: investor decks and financials, CIMs, board packs, client deliverables, course materials, pricing sheets, anything where a copied or printed page would cost you something.

How do you restrict printing and copying in Adobe Acrobat?

Set a Permissions Password in Acrobat Pro with Printing Allowed set to None and copying unticked (Method 2). Adobe's steps, with its exact labels, from its Restrict printing, editing, and copying PDFs page:

1. Select All tools > Protect a PDF.
2. From the left pane, select Encrypt with Password and select Yes in the confirmation dialog box.
3. Select Restrict editing and printing of the document under Permissions.
4. Enter a password in the Change Permissions Password field.
5. From the Printing Allowed dropdown, choose None ("Prevents printing"). Low Resolution "Allows printing at up to 150 dpi"; High Resolution allows any resolution.
6. Leave Enable copying of text, images, and other content unticked.
7. Leave Enable text access for screen reader devices ticked, so blind and low-vision readers can still use the document.
8. Select OK, re-enter the permissions password, select OK, and save.

The Changes Allowed dropdown sits on the same screen if you also want to block edits (None through Any except extracting pages).

What it stops: printing and copying in Acrobat, Acrobat Reader and other readers that honor PDF permissions.

What it doesn't stop: readers and tools that ignore the flags, screenshots, and forwarding. You also can't revoke the file or see who opened it once it's sent; see how to prevent PDF forwarding.

Tip: If the file must also be unreadable without a password, tick Require a password to open the document on the same dialog and send that password through a separate channel. That is access control rather than copy control; how to send a password-protected PDF covers it in depth.

Best for: price lists, internal policies, published reports where you want a clear "don't reuse this" signal for honest recipients.

How do you stop printing and copying a PDF on a Mac?

Use Preview's owner password, which is free on every Mac (Method 3). Apple's steps from Password-protect a PDF in Preview on Mac:

1. Open the PDF in Preview.
2. Choose File > Export. To keep the original unprotected, enter a new name for the protected copy.
3. Click the Permissions button.
4. Leave the checkboxes for printing and copying unselected. Apple's rule: "Select the checkbox next to an action to allow printing or changes without the owner password. Leave the checkbox unselected to require the owner password."
5. Enter a password in the Owner Password section and retype it.
6. Click Apply, then Save.

To change the settings later, open the protected PDF and choose File > Edit Permissions. Apple notes that changes "take effect the next time the PDF is opened."

Preview's permissions are the same PDF flags Acrobat writes, with the same limits: they hold in readers that respect them and nowhere else. Apple's page also offers Require Password To Open Document on the same screen if you need an open password as well.

Best for: Mac users who want Acrobat-style restrictions without paying for Acrobat Pro.

How do you disable printing and copying in a PDF for free?

Use LibreOffice on Windows or Linux, or PDF24's online tool for a one-off (Method 4). Both are free.

LibreOffice (free desktop app):

1. Open the document (or the PDF in LibreOffice Draw) and choose File > Export As > Export as PDF.
2. Open the Security tab and click Set passwords to add the permission password.
3. Under Printing, choose Not permitted.
4. Under Contents, untick Enable copying of content. Leave Enable text access for accessibility tools on.
5. Export.

PDF24 (online or desktop): PDF24's Protect PDF tool says it can "encrypt PDF files with a password and restrict permissions such as printing, copying content, commenting or changing the document." The online version runs on PDF24's servers, which it says are "located in Germany," with files "automatically deleted from the PDF24 server after one hour" (PDF24 Protect PDF). For confidential files, uploading to any web tool is itself a disclosure, so use PDF24's Windows desktop app or LibreOffice instead.

Both write the same reader-honored flags as Acrobat. For the full list of free tools that set open passwords too (Word, qpdf, iOS Files and more), see how to password protect a PDF without Adobe, and to restrict a whole folder of PDFs at once, see how to password protect multiple PDFs.

How do you stop people printing or copying a PDF in Google Drive?

Turn off downloading, printing and copying for viewers and commenters in the file's share settings (Method 5), if the PDF already lives in Google Drive. Google's steps from Stop, limit, or change sharing:

1. Select the PDF (or several files) in Google Drive.
2. Click Share.
3. At the top right, click Settings.
4. Turn off the option that lets viewers and commenters download, print and copy the file (Google renames this setting from time to time; it sits in the share dialog's Settings).

Because the file stays in Drive, you can change or remove access at any time, which permissions passwords can't do. Google is candid about the ceiling, though: "You can limit how people share, print, download, and copy within Google Drive, Docs, Sheets, and Slides. However, you can't stop how others share the file content in other ways." Screenshots and screen recording are untouched, there is no per-viewer watermark, and you don't get page-by-page reading data. The same trade-offs apply to Google Docs; see how to password protect a Google Doc.

Best for: internal or partner sharing where everyone already works in Google Workspace.

When is PDF DRM worth it?

DRM is worth it when you distribute PDFs at volume to people you don't know, such as paid courses, research reports or technical standards, and you can ask every reader to install or log in to a dedicated viewer (Method 6).

Locklizard is a representative example. Protected documents become PDC files that only its Safeguard viewer opens: an installed app for Windows, Mac, iOS or Android, or a browser-based Web Viewer that "requires you to always be online." On first open, the viewer checks with the publisher's server for the decryption key and the rights attached, and Locklizard says its viewer prevents copying, stops screen grabbing with Windows Print Screen and screen-grabber apps, and blocks printing to PDF print drivers, with expiry and revocation controlled by the publisher (Locklizard secure PDF viewer).

The trade-off is friction and cost. Every reader registers and installs (or logs in), which is reasonable for a customer who bought a course and unreasonable for a buyer's analyst on a deal timeline. For one-to-few sharing with counterparties, a browser-based secure viewer gets you most of the control without asking anyone to install anything.

What should you check before sending a PDF you don't want copied?

Check what you're defending against, that downloads and printing are really off, and that every copy can be traced back to a person.

• Decide what you're defending against. If it's casual reuse by honest people, a permissions password is enough. If it's a leak that would hurt, don't send the file at all.
• Never count Low Resolution printing as protection. 150 dpi is perfectly readable, and "printing allowed" opens the print-to-PDF route.
• Keep screen-reader access on. Adobe and LibreOffice both separate accessibility access from copying, so you can block copying without locking out assistive technology.
• Keep an unrestricted master in your own storage, and send a separate protected copy.
• Check that downloads are actually off. In Peony a new link starts with Allow downloads on; open the link in an incognito window and confirm there's no download or print option before you send it.
• Watermark anything you'd need to trace. A per-viewer dynamic watermark doesn't stop a photo, but it puts a name on it, which changes how people handle the document. See can you stop phone photos of documents.
• Remove what nobody should see. If a figure must never leave, take it out of the PDF before sharing rather than relying on any restriction.

What is the best way to protect a PDF from copying and printing?

For anything sensitive, share the PDF view-only through a secure viewer with downloads and printing off; for low-stakes files, a permissions password is enough. Match the method to the cost of a leak:

• Low stakes, any reader: Acrobat Pro permissions password, or Preview, LibreOffice or PDF24 for free. Treat it as a polite signal.
• The file lives in Google Drive and stays internal: Drive's download, print and copy setting.
• Selling PDFs to thousands of readers: PDF DRM, accepting the install friction.
• Investors, buyers, clients, boards: share the PDF view-only through Peony with downloads and printing off, screenshot protection on Business ($30/admin/month), and dynamic watermarks on Data Room ($52/admin/month).

The principle behind all four: restrictions written into a file depend on the recipient's software, and controls on a viewer you run depend on you. If copying or printing the PDF would actually cost you something, choose the second. That's how Peony's 8,000+ customers share the documents they can't afford to lose track of. Start with Peony and send your first view-only link in a few minutes.

Frequently asked questions

Can you prevent a PDF from being copied and printed?

Partly, and only reliably if you never send the file itself. A permissions password set in Acrobat, Preview or LibreOffice asks PDF readers to block printing and copying, but readers that ignore the flags, unlock tools and screenshots all get around it, and the PDF standard (ISO 32000-1) says nothing inherent in PDF encryption enforces those permissions. The dependable approach is to share the PDF view-only in a secure viewer with downloads and printing off, screenshot protection, and a per-viewer watermark.

How do I make a PDF non-printable?

Set a permissions password with printing set to None. In Adobe Acrobat Pro, open All tools, Protect a PDF, Encrypt with Password, tick Restrict editing and printing of the document, enter a Change Permissions Password, and choose None under Printing Allowed. On a Mac, Preview does the same from File, Export, Permissions with an owner password. Both only hold in readers that honor the flag, so for sensitive files share the PDF view-only with downloads off, which also disables printing on PDFs on most modern devices.

How do I stop people from copying text from my PDF?

Turn off copying when you set a permissions password. In Acrobat Pro, untick Enable copying of text, images, and other content; in Preview, leave copying unselected under Permissions; in LibreOffice, untick Enable copying of content. That blocks select-and-copy in readers that honor it, but not unlock tools, screenshots or retyping. For content that matters, share it in a viewer that sends page images instead of the PDF, so there is no PDF text to select, and add a per-viewer watermark.

Can PDF copy and print restrictions be removed?

Yes, easily, when a PDF has only a permissions password. Such a file opens without a prompt, and once it is decrypted the PDF standard leaves enforcement to the reader. The qpdf manual says qpdf itself does not obey encryption restrictions already imposed on a file, and free unlock websites remove them too. A strong document open password is far harder to remove, but it controls who can open the file, not what they do once it is open.

How do I protect a PDF from copying and printing for free?

Use a free tool that sets a permissions password: Preview on a Mac, LibreOffice on Windows or Linux, or PDF24's online Protect PDF tool. Each can block printing and copying in readers that honor the flags. If the PDF already lives in Google Drive, its sharing settings can stop viewers and commenters downloading, printing and copying it. None of these stops screenshots or shows who opened the file; Peony's Free plan adds a tracked link with page-level analytics, and view-only sharing with printing off starts on Business at $30/admin/month.

Does a password-protected PDF stop printing?

Only if it has a permissions password with printing set to None. A document open password controls who can open the file; once someone opens it, they can print and copy freely unless permissions were also set. Adobe documents the two separately: the Document Open Password restricts access to the contents, and the Permissions Password restricts features such as printing, editing and copying content.

What is the best way to share a PDF so it can't be copied or printed?

Share it view-only through a secure viewer instead of sending the file. In Peony, the PDF stays on Peony's servers and viewers receive page images, and with downloads off, printing is disabled too on PDFs and most modern devices. Business ($30/admin/month) adds download prevention and desktop screenshot protection; Data Room ($52/admin/month) adds dynamic watermarks with each viewer's name, email and IP, plus Screenshield for mobile. Viewers are free and unlimited, and Peony is used by 8,000+ customers.

Can someone still screenshot a PDF that can't be copied or printed?

Yes. Permissions passwords and Google Drive's download, print and copy setting do nothing against screenshots or a phone camera. Peony's screenshot protection blocks native screenshot shortcuts and screen recording in supported desktop browsers, leaving a blurred or blank capture (Business, $30/admin/month), and Screenshield reduces capture on iPhone, iPad and Android (Data Room, $52/admin/month). No tool stops a camera, so a dynamic watermark puts the viewer's identity into any photo of the page.
