How to unlock PDF files with Smallpdf

Is this secure?

 

Absolutely.

Smallpdf transfers files for all 18 of our tools via a super secure connection. We can also assure that your files are never read, analyzed or downloaded, and we always delete them an hour after processing. It's only available during this time for you to download after you are not working on your files. Talk about how to unlock PDF files securely and conveniently!

How to prevent files from being unlocked?

 

Funny that you ask! We also have a secured Protect PDF tool for you to do precisely this.

While most PDF files can be unlocked, via using our Unlock function, some cannot. These cases happen when such files are heavily encrypted, thus making nearly impossible to unlock. By doing so, you ensure that it's completely secured for sharing!

If you'd like to read up on how to do this explicitly, do check out our 'How to Encrypt a PDF' guide. Otherwise, access our Protect PDF tool to try it out for yourself. Our Protect encrypts your files so strongly, that not even the Smallpdf password unlocker can decrypt it!

And remember, don't forget your password!

Any feedback, concerns, product requests, bugs or what not, pop us an email, and we will help you out.
