How to unlock a password-protected PDF


Password protecting your PDFs is one the best ways to ensure security. But what happens if a password is lost or forgotten? We’ve got you covered

Some files are sensitive. They might contain private information, or may just need to be made tamper-proof. One way to keep your documents locked up is to use a password to protect them. 

But what happens when you need to make changes and you’ve forgotten the password?

We’ve all been there: the moment of panic when we realize we’ve forgotten the one password we need. The team member managing logins might be on leave. A password could have been changed without records being updated. Your LastPass uninstalled itself, or a file corrupted somewhere along the way. Maybe you just forgot to write it down. 

Fortunately for you, Lumin has the perfect (and free) tool for this problem: our PDF unlocker!
