Frequently Asked Questions

Can I watermark every page of my PDF?

Yes. The watermark you configure is applied consistently to every page of your PDF before you download it.

Are my files uploaded to a server?

No. Everything runs entirely in your browser using pdf-lib and pdf.js, so your PDF and logo never leave your device.

Can I add both a text and an image watermark?

Yes — choose between text and image watermark modes. Adjust opacity and position so the watermark stays legible without hiding your document.

Does the download affect PDF quality?

No. The original pages are preserved and the watermark is drawn on top, so the underlying content stays unchanged.
