Frequently Asked Questions

Is the watermark added to all pages?

Yes. Your text watermark is applied automatically to every page of the PDF in one step.

Can I control the transparency?

Absolutely. Use the opacity setting to make the watermark a subtle background mark or a bold, prominent stamp.

Will the original text of my PDF still be readable?

Yes. A semi-transparent watermark sits over your content without hiding it, so the document remains fully readable.

Is my document safe?

Completely. The watermarking is done inside your browser, so your PDF is never sent to or stored on a server.

Does the tool add its own watermark?

No. Only the watermark text you choose is added — we never brand your files.
