Frequently asked questions

Can a watermark protect my ID documents?

Yes: add for example “Copy for rental application – June 2026” as a tiled pattern to limit fraudulent reuse.

Can it repeat across the page?

Yes, tick the tiled option.

Is it free?

Yes, free and without sign-up, with no file limit and no watermark added.

Are my files uploaded?

No. Processing happens entirely in your browser, on your device. No file is uploaded: it's faster and your documents stay private.
