The short answer
Drop the protected PDF on the tool below. If the file opens without a password and only limits printing or copying, it is unlocked at once. Otherwise the row asks for the password: type it in PDF password and press Unlock or Enter. The file is decrypted and saved without any protection, ready to download. Your original file is not changed.
You can add several files at once. One password field is used for all of them; files that share the password are unlocked together, and the others show Wrong password. Type the next password and press Unlock again, and only the files that are still locked are tried.

Many PDFs arrive protected for good reasons, such as bank statements, payslips, tax documents or contracts. Once the file is safely on your device, the password can get in the way. Common reasons to keep an unlocked copy:
- Archiving: documents in a long term archive should open in ten years too, even if nobody remembers the password.
- Sharing with an accountant, lawyer or family member without sending the password as well.
- Working with other tools: merging, compressing, signing or adding page numbers usually needs an unprotected file.
- Printing or copying text from your own documents when the sender blocked it.
- Uploading to a portal that rejects password protected files.
- Remember that the unlocked copy can be read by anyone who gets it. Store it in a protected place, and do not remove protection from documents you are not allowed to use.
Open password, permissions password and limits
PDF protection comes in two forms. An open password (user password) is needed to read the file at all. A permissions password (owner password) controls what readers allow once the document is open, such as printing, copying or editing. The tool accepts either of them, and both lead to the same result: a copy with no protection.
Some files have only limits: they open without asking for a password, but printing or copying is greyed out. Technically they are encrypted with an empty open password. The tool recognises these files and removes the limits directly, so you do not need the permissions password.
| What you see | What the tool needs | Result |
|---|---|---|
| The PDF asks for a password to open | The open or permissions password | Copy without password |
| The PDF opens, but printing or copying is blocked | Nothing | Copy without limits |
| The PDF opens and everything works | Nothing to do | Shows that there is no protection |
| The PDF needs a certificate or digital ID | Not supported here | Open it in the app your company uses |
Why a forgotten password cannot be removed
In a protected PDF the content itself is encrypted. The password is not a lock on the door that can be skipped; it is needed to compute the key that turns the scrambled data back into pages. Without the right password there is nothing to remove, only encrypted data.
The only way to open such a file without the password is to guess it, by trying millions of possibilities. With modern AES encryption and a decent password this takes far too long to be practical. Sites that promise to remove any password either guess weak passwords on their servers, which means uploading your private document, or only handle the simple case of files with limits. This tool does not guess passwords at all.
If you have lost the password, ask the sender for it or for a new copy. Banks and employers often use a rule, such as part of your date of birth or ID number, which is explained in the email or on their website.
What stays the same after unlocking
- Pages, text, fonts and images are kept exactly as they were. Only the encryption is removed, nothing is converted or compressed.
- Links, bookmarks, form fields and attachments stay in the file.
- Text becomes searchable and copyable in every app, and the file opens without a prompt.
- A digital signature becomes invalid, because removing the protection changes the file. Keep the original if the signature matters, for example for contracts or official documents.
- The unlocked file can be a little smaller or larger than the original, because it is written again in a compact form.
Common problems and fixes
- Wrong password, although you are sure: passwords are case sensitive. Check Caps Lock and the keyboard language, and make sure no space was added when you pasted it. Use Show to see what you typed.
- The password has special letters: type it exactly as the sender wrote it. The tool tries the common ways these letters are stored in PDF files.
- The file says it has no password or limits: it is not protected, so you can use it as it is.
- The file says it uses a certificate: this kind of protection is linked to a personal digital ID, not a password. Open it in the app or service it was made for.
- The file cannot be read at all: it may be damaged or not a real PDF. Ask the sender for a new copy.
