Strong Encryption: We apply industry-standard PDF encryption so only someone with the correct password can open or edit the file.

Passwords Never Stored: We never save the password you set — it exists only in the protected file itself.

Granular Permissions: Restrict printing, copying, and editing independently from the password required to open the document.

Automatic Deletion: The unprotected original is deleted from our servers within 1 hour of processing.

Frequently Asked Questions

What type of passwords can I set?
You can set a strong user password to restrict opening the document, or an owner password to restrict actions like printing, editing, or copying content.
What encryption standard does the tool use?
We use secure, standard PDF encryption algorithms to ensure your passwords cannot be easily bypassed by common PDF viewers.
What should I do if I forget the password?
Because we prioritize privacy and do not store passwords, we cannot recover forgotten passwords. Make sure to keep a secure record of the password you choose.
Can anyone edit my protected PDF without a password?
No, once encrypted with permissions, PDF readers will disable editing, copying, and printing features unless the owner password is provided.
Will the document name be encrypted too?
The file name remains visible, but the entire internal contents, metadata, and structural tree are fully encrypted and protected.
