FAQ
Q. Can I crack a PDF password if I do not know it?
No. This tool is designed to remove the password permanently for users who already know the authorized password (to save time entering it again). It cannot bypass or crack unknown passwords.
Q. Will the unlocked PDF open without prompting for a password in the future?
Yes. Decryption removes all security dictionary nodes. The newly generated PDF will open freely on any device or software without asking for credentials.
Q. Are my uploaded files and passwords private and secure?
Yes. Decryption is performed entirely using client-side JavaScript in your browser memory. Neither your files nor your password values are transmitted to or saved on our servers.
Q. Can I remove print/edit/copy restrictions?
Yes. Entering the correct password allows you to strip printing, editing, and content copying permission restrictions in one click.
Q. Will the unlocked PDF lose image quality or corrupt text data?
No. Decryption merely decrypts the encrypted object streams without re-rendering or compression. The layouts, vector data, and images remain completely untouched.
Q. What is the maximum file size limit?
You can upload and decrypt documents up to 100MB in size.
Q. Does this utility work on mobile devices?
Yes. Our responsive layouts work perfectly on mobile platforms including iOS Safari, Chrome on Android, and iPadOS.
Q. Is there an account requirement or charge?
No. The platform requires no registration, signup, or subscriptions, and it is 100% free.
Q. Will my original file on my local computer be overwritten?
No. The uploaded file is read-only. The platform synthesizes a new decrypted PDF in local memory and downloads it, preserving your original document.
Q. Can I apply a new password to the unlocked PDF later?
Yes. You can upload the clean decrypted PDF file to our PDF Protect tool and encrypt it with a fresh secure password.
