Frequently asked questions

About PDF Password Protector and how Tarumak Studio works.

What encryption standard is used?

256-bit AES encryption — the same standard used by modern PDF viewers and recommended for sensitive documents.

Can I restrict printing or copying separately from opening?

Yes — opening password and owner permissions (printing, copying, editing) are independently configurable.

Can the password be removed later?

Yes — use the PDF Unlock tool with the correct password to remove protection from your own documents.

Is PDF Password Protector really free?

Yes — completely free, with no usage limits, no watermarks and no premium wall. Every tool on Tarumak Studio is free to use.

Do I need to create an account?

No. There is no sign-up, no login and no email required. Open the tool and use it immediately.

Are my files uploaded to a server?

No. PDF Password Protector runs entirely in your browser — your files are processed locally and never uploaded, which also makes it faster than server-based alternatives.

What formats does it support?

PDF Password Protector works with PDF.

Does it work on mobile?

Yes. The tool runs in any modern browser on desktop, tablet or phone — no app install needed.
