How to Unlock a PDF and Remove Its Password Online for Free
Remove a PDF password in two steps: upload the file and enter the current password. Download your unlocked PDF instantly. No software, no account, file deleted after 1 hour.
When do you need to unlock a PDF?
You forgot the password to a document you created. You received a password-protected file and need to forward it to colleagues. You want to print or edit a document with permission restrictions. You are archiving old documents and want to remove outdated protection. Always ensure you own or have authorization for the document before removing protection.
Open password vs permission restrictions
Open (user) password: prevents anyone from opening the file. Our tool removes this entirely. Permission (owner) password: allows the file to open but restricts printing, copying or editing. Our tool removes these restrictions. Both types are handled automatically when you provide the correct password.
FAQ
Do I need to know the current password?
Yes. Our tool removes protection only after you provide the valid password. It does not bypass or crack encryption without the password.
Is it legal to unlock a PDF?
Yes, if you own the document or have explicit permission from the owner. Removing protection from someone else's document without authorization is illegal.
Will the unlocked PDF retain all its content?
Yes. All text, images, fonts, hyperlinks and annotations are preserved. Only the password protection layer is removed.
Does this work for PDFs with DRM (Digital Rights Management)?
No. Standard PDF password protection is supported. DRM-protected PDFs (Adobe DRM, Locklizard) are not supported.
How secure is the unlocking process?
Your file is transferred via HTTPS TLS 1.3 and deleted automatically after 1 hour. The password you enter is used only for decryption and is never stored.
Can I unlock a PDF on my phone?
Yes. FileSwiftly works in any mobile browser without requiring an app download.
