Remove a known PDF password
FigureOwl creates a new copy that opens without asking for the current password. This is useful when you own the document, know its valid password and need a password-free copy for an approved workflow such as archiving, importing into another app or sharing through an access-controlled system.
You must know the existing password
This tool does not crack, guess, recover or bypass an unknown password. Enter the valid opening or owner password supplied for the document. Use the tool only on a PDF you own or are authorized to modify.
Private browser-local decryption
The PDF and password are handled in browser memory by qpdf compiled to WebAssembly. They are not uploaded to FigureOwl, saved in an account, written to server logs or used to train a model. The protection engine is loaded by the page, but the document itself stays on your device.
The original PDF remains unchanged
FigureOwl downloads a separate unlocked copy and does not alter or delete the protected source file. Keep the original until you have opened and checked the result. The downloaded copy is unencrypted, so anyone who obtains it can read it without the old password.
When removing a password is useful
A password-free copy can help when a document system, print service or accessibility workflow cannot repeatedly prompt for a password. It can also simplify an authorized personal archive. Store the result only in a location with suitable device, folder or account security.
Digital signatures may no longer validate
Removing encryption rewrites the PDF structure. That can invalidate an existing certificate-backed digital signature even when the visible pages do not change. If signature validity matters, inspect the downloaded copy in a trusted PDF reader and preserve the signed original.
What happens to permissions restrictions
The output is an unencrypted PDF without the previous password security settings. PDF permission flags are not a substitute for access control and may be handled differently by different readers. Make sure you are authorized before removing them.
Verify the password-free copy
Open the downloaded file without entering a password, review every page and confirm the expected text, forms, attachments and signatures. If the password is incorrect, FigureOwl stops and does not create an unlocked download.
