Unlock PDFs Instantly
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 password-protected PDF document.
Data Protection & Security First
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.
Unlock PDFs on Any Platform
As a cloud platform, Smallpdf welcomes Windows, Mac, or Linux, Android, or iOS users. Our unlock PDF feature and other online tools work on all systems, as long as there's an internet connection.
Unlock Almost Any PDF
If your file is protected with an owner password, we can unlock the PDF instantly. Strongly encrypted PDF files can only be unlocked with the correct passwords.
PDF Password Removal Made Easy
Unlocking a protected PDF file is easy with Smallpdf. You just need to upload your secured PDF, enter the user password (for strongly encrypted files), and download the unlocked PDF!
