Unlock PDF — Remove Password Free Online

Remove password protection from a PDF you own. Enter the password once, get an unlocked copy back. Runs in your browser — the PDF and password never touch our servers.

How to remove password protection from PDF

Drop the protected PDF onto the box above. The tool checks that it's actually encrypted, then asks you for the password. Type it, click Unlock PDF, and an unlocked copy downloads a moment later. Open the new copy in any PDF viewer — no password prompt, no restrictions.

The tool never sees or stores your password. Every step happens in your browser using client-side JavaScript. If you check DevTools → Network tab while unlocking, you will see no PDF or password upload requests.

This is not a password cracker

You need to know the PDF password. This tool decrypts using the password you provide — the same way Adobe Reader does when it shows the password prompt. A properly-encrypted PDF (any version's AES) with a decent password cannot be broken by any online tool. Sites that advertise "unlock PDF without password" either:

  • Send your PDF to their server, where they might try a dictionary attack (only works on obvious passwords) — and now they have your document.
  • Only work on PDFs with the older, weaker RC4-40 cipher (obsolete since ~2005). Modern PDF encryption is safe.
  • Only remove "owner password" permission restrictions (the ones that prevent printing/copying), which is a much weaker layer than the "user password" that gates actually opening the file.

If you forgot a password you set yourself, check password managers (1Password, Bitwarden, Apple Keychain, Google Passwords), browser saved passwords, notes app or paper. If someone else set it, ask them.

When would you want to remove a PDF password?

  • Bank statements your bank emails you with a standard password (date of birth, PAN, etc.). Once downloaded and verified, remove the password so you can search and print without typing it every time.
  • Salary slips from HR — many companies protect these with employee ID as the password. Unlock once after downloading; store the unlocked copy in your personal files.
  • Invoices and receipts for expense reports — some accounting systems reject password-protected PDFs; you need to unlock before submitting.
  • PDFs you password-protected yourself that you now want to share without the password overhead.
  • Archiving important documents — a password-protected PDF is one forgotten password away from being unrecoverable. Unlock and store somewhere secure (encrypted disk, password manager attachment).

Removing PDF password without Adobe Acrobat

Adobe Acrobat Pro can remove PDF passwords via File → Properties → Security → No Security, but requires a paid subscription (~$20/month). Adobe Reader (free) can only open protected PDFs, not modify them. This tool does the same job as Acrobat Pro's password removal, running in your browser instead of a paid desktop app.

How PDF password removal actually works

A password-protected PDF has an encrypted content stream. When you enter the password, the PDF viewer derives an encryption key from it (via a key derivation function like PBKDF2), then decrypts the content on the fly for display. To create an unlocked copy, this tool decrypts the same way, then re-saves the pages into a fresh PDF that has no encryption layer at all — not "encrypted with an empty password" but genuinely unencrypted, so it opens instantly in every viewer.

How to remove PDF password on iPhone or Android

Works on any modern mobile browser: Safari (iPhone/iPad), Chrome (Android), Samsung Internet, Firefox Mobile. Tap the drop zone, pick the protected PDF from Files, Downloads, iCloud Drive or Google Drive, enter the password, tap Unlock. The unlocked copy downloads to your device. No app install needed.

Privacy — the PDF and password never leave your device

Because both the PDF and the password are handled in your browser, nothing about them reaches our servers or any third party. This matters especially for password-protected PDFs because they're usually confidential (bank statements, medical records, salary slips, ID copies) — the whole reason they were protected in the first place is that the content is sensitive. Uploading such a PDF to an online unlocker defeats the protection: even if the unlocker deletes the file after processing, you now have to trust their word for it. A browser-only tool removes that trust question entirely.

Frequently asked questions

How do I remove password protection from a PDF for free?
Drop the protected PDF onto this page, enter the password, and click Unlock. The tool decrypts the file in your browser using the password you provided and downloads an unlocked copy. Free, no signup, no watermark.
Do I need to know the password?
Yes. This tool is not a password cracker — it uses the password you enter to legitimately decrypt the PDF. A properly-encrypted PDF (AES-128 or AES-256) with a strong password cannot be broken by any online tool; if it could, PDF encryption would be worthless.
How do I un-password protect a PDF I own?
If you set the password yourself, you can remove it: drop the PDF, enter your password, click Unlock, download the unprotected copy. Same for PDFs shared with you where you were given the password (bank statement, salary slip, invoice).
What if I forgot the PDF password?
The password cannot be recovered from the PDF. If you set it yourself, check your password manager (1Password, Bitwarden, Apple Keychain, Google Passwords), sticky notes, or wherever you store passwords. If someone else set it, ask them for it. Password-cracking tools you see advertised online either send your PDF to a cloud service (privacy risk) or only work on very weak passwords.
Is my PDF and password uploaded?
No. Both the PDF and the password are processed entirely in your browser using JavaScript. Nothing about the document or password reaches our servers or any third party. Verify by opening DevTools → Network tab while unlocking — no PDF or password uploads appear.
What kind of PDF encryption is supported?
All standard PDF encryption: RC4 (older, 40-bit and 128-bit), AES-128 (Acrobat 7+ default) and AES-256 (Acrobat X+ and modern tools). If it opens with a password in Adobe Reader, this tool can unlock it with the same password.
How do I remove PDF password on iPhone or Android?
Open this page in Safari (iPhone) or Chrome (Android). Tap the drop zone and pick the protected PDF from Files, Downloads or your cloud storage. Enter the password and tap Unlock. The unlocked PDF downloads to your device.
