How to Remove a PDF Password on Mac

macOS ships with Preview, which can technically resave a PDF, but Preview's password handling has real limits that catch a lot of Mac users out. Here's what Preview can and can't do with a locked PDF, and how to remove a password or restriction on a Mac using nothing but the browser you already have, without installing anything from outside the App Store.

What Preview.app can actually do

Preview, the PDF and image viewer built into every Mac, can open a password-protected PDF if you know the password, and from there you can use File > Export and, in the resulting dialog, leave the encryption options unchecked to save an unprotected copy. That workflow does exist, and for a document you can already open, it can work.

Where it gets less reliable is exactly the two situations that send most people searching for help: a PDF that's locked with owner/permissions restrictions but has no visible password prompt at all (Preview doesn't surface a clear “remove restrictions” option for this case, since there's no lock screen for it to react to), and a PDF you can't open because you don't know the password (Preview simply refuses, correctly, since it has no way to guess a password you haven't supplied).

The permissions-restricted case Preview doesn't make obvious

A lot of “PDF won't let me print or copy on my Mac” problems are not open-password problems at all: the file opens instantly in Preview with no prompt, but the Print command is greyed out, or Cmd+C on selected text does nothing. That's an owner/permissions password, and Preview's export flow doesn't clearly expose a way to strip it, since Preview isn't really built as a PDF security tool, it's a general-purpose viewer.

This free browser tool is built specifically for that case. Drop the file in from Safari, Chrome, or any Mac browser, and because the PDF opens with no password, the tool reads it and strips the restriction automatically, handing back an unrestricted copy in a few seconds.

Removing a password-to-open PDF on Mac, when you know the password

If the PDF prompts for a password before showing any content and you know that password, this tool decrypts it the same way Preview's export flow would, just without needing you to trust Preview's export dialog to get the settings right. Drop the file in, enter the password when asked, and the tool decrypts it locally in your browser tab using qpdf compiled to WebAssembly, a real cryptographic library rather than a simplified reimplementation.

Because everything runs inside the browser's own sandboxed environment, the process works identically whether you're on an Intel Mac, an Apple Silicon Mac (M1 through M4 and beyond), or an older machine still a few versions behind on Safari or Chrome: there's no native app to be incompatible with your chip architecture or macOS version.

Why this beats installing a third-party Mac PDF app

Searching “remove pdf password mac” turns up a long list of paid utilities and App Store apps that promise to do this, many of which require a purchase, ask for an email address to unlock the feature, or, worse, quietly upload your file to a server as part of “cloud processing”. None of that is necessary for a task this simple. This tool runs the whole operation in your existing browser, with no install, no account, and no file leaving your Mac at any point, which you can verify yourself by opening Safari's or Chrome's developer tools and watching the Network tab while you use it.

It's also just faster: no App Store download, no permission prompts for a new app to access your files, no waiting for an installer. You drop the file in and get a clean copy back in seconds.

If the PDF needs a password you've forgotten

None of the above helps if you've genuinely forgotten the password required to open the file, and neither will Preview, nor any other Mac app that isn't specifically built to test candidate passwords. That's a different, much slower problem, covered honestly in our guide to recovering a forgotten PDF password: weak or human-chosen passwords have a real chance of being found, strong random ones do not, on a Mac or any other platform.

It's worth pausing on the distinction between a forgotten password and an unknown restriction, because the two get conflated constantly on Mac forums. If the file opens instantly in Preview with no prompt at all, you don't have a forgotten-password problem, you have a permissions restriction, and the fix above (dropping it into this tool) removes it with nothing to remember. The forgotten-password path only applies when macOS itself refuses to render the document without a password you can't supply.

Batch-unlocking multiple PDFs on Mac

A common Mac-specific request is unlocking a folder full of restricted PDFs at once, exported statements, scanned receipts, a semester's worth of course readings. Preview has no batch tool for this at all; each file has to be opened, exported, and re-saved individually, which gets tedious past a handful of files. This tool doesn't currently batch-process multiple files in one drop, but because each file takes only a few seconds from drag to download, working through a folder of restricted PDFs one at a time in a single Safari tab is still considerably faster than the manual Preview export cycle, especially since there's no dialog to double-check on each one.

A note on Finder Quick Look and PDF security

One more Mac-specific gotcha: Finder's Quick Look (hitting spacebar on a selected file) can often preview a restricted PDF's pages even when Preview's own print/copy commands are greyed out, which understandably confuses people into thinking the restriction isn't really doing anything. Quick Look is just rendering pixels for a glance; it doesn't expose an export or print path, so it isn't actually bypassing anything, and it's not a way to get an unrestricted copy. If you need to actually print, copy text from, or edit the file, you're back to needing the restriction removed properly, which is what this tool does.
