Smallpdf transfers files for all of our tools via a super secure connection. For the best result, do go for a password length of more than eight characters, with a few special characters also thrown in.
Because our protect tool encrypts your data so strongly that not even the Smallpdf password unlocker can decrypt it, be sure to keep track of your new password. As we don’t want to meddle, we don’t store or save your chosen password. Of course! To secure a password-protected PDF file, you can go to the Protect PDF tool, upload the document again, and we’ll encrypt it with a strong password. For instance, if someone used our Protect tool to encrypt their file, there’s simply no opening it without a password. In the spirit of full disclosure, we’d like to mention that our tool can’t recover forgotten PDF passwords, and there are some files that even we can’t crack. You’ll be able to view and edit your PDF instantly-unless the file was also secured against editing.
As soon as our unlock tool is done, your file won’t be password protected anymore.
