How to Unlock a PDF
Remove a PDF password in three steps:
- Drop the locked PDF - The tool reads the encryption level and shows which restrictions exist right away.
- Enter the password if asked - Only open passwords require typing. Permission passwords that merely block printing or copying are bypassed automatically.
- Unlock and download - The decrypted copy is verified to open without a password, then saved as a normal PDF.
Open Passwords, Permission Passwords, and Encryption Levels
Password protected PDFs use two different kinds of locks. Knowing which one you have changes what you need to unlock the file.
- Open password - The file will not display at all until the password is entered. You need that password here; there is no legitimate way around it.
- Permission password - The file opens normally but refuses printing, copying, or editing. This tool clears those restrictions without any password, because the viewing key is already public.
- Encryption levels - The report shows AES-256 (modern default), AES-128, RC4-128, or RC4-40 (legacy) before you unlock.
- Restriction diff - The before and after table lists print, copy, modify, form, and annotation rights so you can see exactly what changed.
- Built-in verification - The output is reopened without a password before download, so you never receive a half-decrypted file.
Unlock PDF Files Without Uploading
Locked documents often carry contracts, invoices, or client data. Here the file never leaves your device: analysis, decryption, and verification all happen in the tab. Pair this with PDF to JPG to share pages as images, the PDF Tools hub for the rest of the toolkit, or the Rotate PDF tool for quick fixes.

Frequently Asked Questions
How do I unlock a PDF?
Drop the PDF. If it needs an open password, type the password you use to view it, then press Unlock PDF. The decrypted copy downloads immediately and the tool verifies it opens without any password.
What is the difference between an open password and a permission password?
An open password blocks viewing until the password is typed. A permission password (sometimes called an owner password) lets the file open freely but blocks printing, copying, or editing. This tool handles both: permission locks are removed without typing anything, while open passwords need the correct password first.
Is my password safe?
Yes. The password is typed into your browser tab, used in local memory for the decryption, and never sent anywhere. There is no server in this tool at all; the unlock engine runs on your device.
Which encryption does this handle?
AES-256, AES-128, RC4-128, and RC4-40 PDFs. The tool shows which level your file uses before you unlock it.
What restrictions get removed?
Everything. Print, copy, modify, form filling, and annotation restrictions are cleared, and the before and after table shows the difference on your file.
Does unlocking weaken the file?
Yes, by design. The unlocked copy is a normal unencrypted PDF that anyone can open. Keep the original if you still need the protection.
Does the tool verify the result?
Every unlock is checked locally before download: if the result fails to open without a password, you get an error instead of a broken file.
