Nowhere. This tool runs inside your browser, and the page is served with a policy that forbids it from sending your document anywhere. You can confirm that yourself: open your browser’s developer tools, watch the Network tab, and process a file.
Questions
- Can the watermark be removed by someone else?
- A watermark is drawn into the page content, so it cannot be toggled off in a viewer. It is a visible deterrent and a clear status marker, not a security control — it can be removed by someone with the right tools and enough determination.
- Can I use an image as the watermark?
- Not in this version. Text watermarks are supported now, and image watermarks are planned for a later release.
- Will the watermark cover my text?
- That is up to you. Lower the opacity so the page stays readable through the mark, which is the usual choice for DRAFT or CONFIDENTIAL stamps.
- Can I watermark only some pages?
- Not in this version — the mark is applied to every page. If you need it on a subset, extract those pages first, watermark them, then merge them back.
- Will the watermark show when the document is printed?
- Yes. It is drawn into the page content rather than added as a viewer annotation, so it prints exactly as it appears on screen.
- Can I change the colour?
- Not yet. The mark is a neutral grey chosen to stay legible against both white pages and printed text at any opacity. Colour control is planned.
- What opacity should I use?
- Around 20 to 30 percent for a mark across body text, which stays clearly visible without making the page hard to read. Go higher for a corner mark that does not overlap content.
- Does adding a watermark make the file much bigger?
- Barely. The mark is a small amount of text drawn on each page, so the increase is a few kilobytes even on a long document.
