Frequently asked questions
What if I forget the password?
It cannot be recovered. Keep the password somewhere safe and keep an unprotected original.
Are the permissions enforced?
Most PDF apps respect them, but they are a courtesy. The password to open the file is the real protection.
Is my PDF uploaded anywhere?
No. The PDF is read and processed by JavaScript in your browser. Only the website's own code and assets are downloaded.
Do I need to create an account?
No. Every tool works without sign-up or login.
Is it safe for confidential documents?
Files are processed locally in your browser and never uploaded. Close the tab or select Clear to release them from memory.
