Uses PDF's built-in Helvetica standard font (selectable text). Non-Latin text is not currently supported; use a Latin label. For a heavy, non-removable "DRAFT" overlay, combine with very low opacity on every page.

FAQ

About watermarking

Do you upload my PDF?

No. Everything runs in your browser.

Is the watermark selectable text?

Yes — Helvetica is embedded as a standard font, so the watermark is real, selectable text. It can be removed by anyone with PDF editing tools; this is a visual notice, not DRM.

Can I add an image watermark instead?

Not in this version. Text only. Image watermarks are planned.
