Frequently Asked Questions
What types of restrictions can it remove?
It removes owner-password restrictions: copy/paste protection, print restrictions, and edit locks. It cannot remove user-password protection (the open password required to view the PDF).
Are my files uploaded to a server?
No. All processing happens 100% in your browser using client-side JavaScript. Your files never leave your device.
Is it legal to unlock PDFs?
Unlocking PDFs you own or have legitimate access to is generally legal. This tool is intended for removing restrictions on your own documents.
Does it work with all encrypted PDFs?
It works with owner-password protected PDFs (restriction-only). PDFs that require a password to open (user-password) cannot be unlocked without the password.
Will the unlocked PDF look different?
No. The output is visually identical. Only the internal permission flags are changed to allow copy, print, and edit.
What is the maximum file size?
You can unlock PDFs up to 100 MB. Processing capability depends on your browser and device memory.
