Unlock PDF

Remove passwords from PDFs online easily for free. No size limits and no ad watermarks.

We can remove the password from your PDF files instantly. If you don't know the password and the file isn't strongly encrypted, we can also unlock your PDF.

Smallpdf uses TLS encryption in all processes. No data entered (like passwords) is stored on our servers. Your files are automatically deleted after one hour.

As a cloud platform, we welcome Windows, Mac, or Linux, Android, or iOS users Smallpdf works on all systems, as long as there's an internet connection.

If your file is protected with an owner password, we can unlock the PDF instantly. Strongly encrypted PDFs can only be unlocked with the correct passwords.

Unlocking a PDF is easy with Smallpdf. You just need to upload your PDF, enter the password (for strongly encrypted files), and download the unlocked PDF!
