A label the document can't lose

Email subjects get deleted, cover notes get separated from attachments โ€” but a watermark travels inside the file itself. Whoever opens the PDF, wherever it gets forwarded, the DRAFT stays visible across every page. That's the point: status that can't be accidentally ignored.

The text is stamped diagonally corner-to-corner, sized to the page automatically, in gray at the opacity you choose. At the default 15% it reads clearly without fighting the content; push it to 30โ€“50% for scans and image-heavy documents where a faint mark would drown. Ironically, documents marked CONFIDENTIAL are the last thing you want to upload to a random converter site โ€” here the stamping happens entirely on your machine.

Frequently asked questions

Can the watermark be removed later?
It is drawn as a normal PDF layer โ€” casual viewers cannot remove it, but PDF editing software can. Treat it as a strong label, not as cryptographic protection.
What text can I use?
This first version supports Latin letters, digits and common punctuation (the standard PDF Helvetica font). Cyrillic and CJK watermarks are on the roadmap.
Does it go on every page?
Yes โ€” the same stamp, automatically sized to each page, even when the document mixes portrait and landscape pages.
