If you have a PDF you can already open but you are tired of typing its password every time, you can remove the password to create a clean, unencrypted copy. This is unlocking — and it is completely different from "cracking", which means defeating a password you do not know.
Unlocking is not cracking
PDFelly will only remove a password if you supply the correct one. It uses that password to legitimately open the document, then saves a decrypted version. It cannot and will not recover or bypass a password you do not have. That is by design: a tool that cracked unknown passwords would be a tool for opening other people's private files.
How to unlock a PDF in PDFelly
- Open the Unlock PDF tool and add the protected file.
- Enter the password you normally use to open it.
- Click Unlock and download the unencrypted copy.
Keeping text selectable
A good unlock preserves the document exactly — text stays selectable and searchable, images keep their resolution. PDFelly opens the encrypted file with the correct password and re-saves it without encryption, which is lossless. Only if a file uses an unusual encryption scheme that cannot be opened that way does it fall back to rebuilding pages as images, and it tells you when that happens.
Why do this in the browser
Removing a password means the decrypted content briefly exists in clear form. You really do not want that step happening on a remote server. Doing it locally keeps both the password and the decrypted file on your own device.

Unlocking versus cracking — why the difference matters
Removing a password you know is routine housekeeping; defeating one you do not know is an attack. PDFelly only does the former. It uses the password you provide to open the document legitimately and then saves a copy without encryption. It has no facility to guess, reset or bypass an unknown password, and that limitation is intentional — a tool that opened arbitrary protected files would be a tool for reading other people's secrets.
Keeping the document fully intact
The best unlock is lossless: the decrypted copy is identical to the original minus the encryption, so text stays selectable and images keep their resolution. PDFelly opens the file with your password and re-saves it directly. Only when a file uses an unusual encryption scheme that cannot be opened this way does it fall back to rebuilding pages as images — and it tells you when that happens so you are never surprised by non-selectable text.
Why do this locally
Unlocking necessarily produces an unencrypted version of a document you cared enough about to protect. Doing it on a remote service means that cleartext file, and your password, briefly live on someone else's machine. Processing in the browser keeps both on your own device from start to finish.
Frequently asked questions
Can PDFelly open a PDF if I don't know the password?
No. You must supply the correct password. PDFelly cannot crack or bypass unknown passwords by design.
Will the unlocked file keep its selectable text?
Yes, in almost all cases. The lossless path preserves text and images exactly. A rare image-based fallback is used only for unusual encryption, and you are told when.
Is removing a password legal?
Removing protection from a document you own or are authorised to use is fine. Do not remove protection from files you are not entitled to access.
Does the password get uploaded?
No. Both the password and the decrypted file stay in your browser.
When a password is more trouble than protection
Passwords earn their keep in transit, but a permanently encrypted working copy can become a daily nuisance — re-typing a passphrase every time you open a reference document, or fighting software that will not preview a protected file. If you are the legitimate owner and the file lives somewhere already secure, such as an encrypted drive or a private device, removing the document-level password often makes sense; the disk encryption protects it at rest, and you stop paying the convenience tax of unlocking it constantly. The decision is about where the protection should live. Keep the password where the file travels through untrusted channels; consider removing it where the surrounding storage already provides security and the password only adds friction. Whatever you decide, keep a protected copy of anything you may need to send onward, and remember that unlocking only works with the correct password — there is no back door.
