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 still unlock your password-protected PDF document.

Data Protection & Security First

Smallpdf uses TLS encryption to keep your files secure during processing. Passwords entered are never stored, and all uploaded files are automatically deleted from our servers after one hour.

Unlock PDFs on Any Platform

As a cloud platform, Smallpdf supports Windows, Mac, 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!
