Unlock PDF

Remove password protection from a PDF — 100% private, processed in your browser.

Unlock PDF removes password protection from a document you're allowed to access — whether it needs a password just to open, or only restricts copying and printing. If it requires a password to view, enter it and the file is decrypted directly; if it only restricts copying or printing, no password is needed at all. The pages are re-rendered at high resolution and rebuilt into a new PDF, so the result looks identical to the original.

What you can do

  • Removes an open password when you know it.
  • Handles PDFs that only restrict copying or printing, with no password needed at all.
  • Pages are re-rendered at high resolution, so the result looks identical.
  • No server-imposed page limit and no account.

How it works

  1. 1Drop your protected PDF onto the page.
  2. 2If it requires a password to open, enter it in the Open Password field — leave it blank if it only restricts copying or printing.
  3. 3Click Process File.
  4. 4Click Download to save the unlocked PDF.

This tool runs inside your browser tab. Your file is read from your device, processed there, and handed back as a download — it is never sent to a SmilingPDF server, so there is nothing for us to store, read, or lose. You can check for yourself: open your browser's developer tools, switch to the Network tab and run the tool. Like most sites, SmilingPDF uses Google Analytics to count visits and which tools are used; that never includes the contents of your files. The privacy policy lists everything the site does collect.

FAQ

Frequently asked questions

Got questions? We've got answers.

What kind of PDFs can this unlock?

It can remove both open-password protection (requires a password to view) and owner-password restrictions (copy/print disabled). For open-password PDFs you must supply the correct password.

Do I need to enter a password?

Only if the PDF requires one to open. Many protected PDFs only restrict copying/printing and can be unlocked without a password — just leave the field blank.

Is my file uploaded to a server?

No. Everything happens locally in your browser. Your file never leaves your device.

Will the unlocked PDF look the same?

The pages are rendered at 2× resolution and re-embedded as high-quality images, so it will look identical. The resulting file is image-based (not text-searchable).

Is there a file size limit?

SmilingPDF imposes no limits. Processing happens in your browser, so it depends on your device memory.
