Frequently asked questions
Does this make my PDF completely secure?
A password limits who can open the PDF, but no tool can guarantee absolute security. Use a strong password and keep it private.
Is my file uploaded to set the password?
No. The password is applied locally in your browser; the file is not sent to a server for this tool.
Can I remove a password later?
If you know the password, you can open the file; removing protection is a separate operation in the app.
Is it safe? Are my files uploaded?
These tools run locally in your browser — for supported local operations your files are not uploaded to a server. Processing the document on your own device avoids sending it to a third party.
