Add a watermark to PDF
DRAFT, CONFIDENTIAL, SAMPLE, DO NOT DISTRIBUTE — a diagonal stamp across every page says what headers can't. Type your text below, tune color, size, and opacity, and stamp the whole document in one pass. Faded enough to read through, bold enough to photograph badly — which is exactly the point for pre-release and review copies.

- 2Tune the look pick gray, red, or blue; set size and fade it to 15–30% so text stays readable.

Watermarks that work
25% is the sweet spot
Clearly visible on screen and print, yet body text reads straight through it.
Red means business
CONFIDENTIAL in muted red photographs worst — ideal for leaks-prone drafts. Gray suits internal reviews.
Size to the page
72pt suits letter/A4; sprawling drawings and posters want 100pt+ to span the sheet.
Frequently asked questions
How do I add DRAFT to a PDF?
Drop it above — DRAFT is pre-filled. Tune size and opacity, hit Add watermark, download.
Can I watermark only some pages?
The stamp applies to every page by design — split out the pages first if only some need marking.
Can watermarks be removed later?
They're baked into a new file here, so removal means editing — which is the point. Anyone with the original can of course re-export cleanly.
Will text stay readable under it?
Yes at sane opacities — 25% gray reads through perfectly while still marking the page.
Are my files uploaded?
No. Stamping runs 100% in your browser.
