Unlock PDF — Remove Passwords & Restrictions, 100% In-Browser
Free your PDFs from password protection and usage restrictions without uploading a single byte. Drop in a protected file, enter the password only if one is required, and download an unlocked copy — the decryption runs locally using the standard RC4, AES-128 and AES-256 algorithms every PDF reader understands. Your file and password never leave your device.
Frequently Asked Questions About Unlocking PDFs
How does the PDF unlocker work?
Drop in a protected PDF and the tool checks its security in your browser. If a password is required you will be asked for it; if the file only carries restrictions (like no printing or copying) no password is needed. The encryption is then removed locally and an unlocked copy is ready to download.
Why does my PDF open without a password but still seem locked?
Many PDFs protect the document with an owner password only. They open freely but restrict actions such as printing, copying or editing. This tool detects those restrictions and rebuilds the file so the limits are gone — no password required.
Which encryption algorithms are supported?
All common ones: RC4 (40–128 bit), AES-128 and AES-256, covering PDF revisions 2 through 6. If a file uses a rare or non-standard handler, the tool will tell you it could not read it as a PDF.
Can you help if I forgot my password?
No — PDF passwords use strong cryptography and cannot be recovered or bypassed. An unprotected PDF can never be "decrypted" without the password, so only files whose password you know can be unlocked.
