Options
What the watermark says.
Helvetica.
How much of the page shows through. 1 is solid.
How far in from the edge the stamp sits. Ignored when it repeats.
Advanced
A TrueType or OpenType font to set the text in. Needed for anything the built-in typefaces cannot draw — Greek, Cyrillic, Arabic, Chinese. The file is read here, in this tab, and embedded in the PDF.

What this does
This stamps text or a logo across the pages — at an angle, at an opacity, once in the middle or tiled across the whole sheet, over the content or underneath it. It becomes part of the page rather than an annotation a reader can hide, move or delete, which is the difference between marking a document as a draft and asking politely that it be treated as one.
What it will not do
Every tool here says what it cannot do, in its own words, before you rely on it.
- A stamp placed under the content is hidden by anything opaque already painted over that part of the page — a scan, or a full-bleed background.
- A repeated stamp is spaced no more finely than a sixtieth of the sheet, so a very small stamp is spread further apart rather than repeated tens of thousands of times.
- Shaping and joining come from the font itself, and nothing reorders a line: text is drawn in the order it is given, so a line mixing right-to-left and left-to-right writing comes out in that order rather than in reading order.
Questions people ask
Can the recipient remove it?
Not by clicking on it. It is drawn into the page’s own content, not added as an annotation, so there is nothing to select or delete. Anyone determined enough can edit a PDF, but this is not a note that vanishes when they press Delete.
My watermark is invisible on a scanned page.
You have placed it under the content, and a scan is one opaque image covering the whole page. Place it over the content instead, and use opacity to keep the page readable.
Is my file uploaded anywhere?
No. The work happens in this browser tab, on your own machine. There is no server in this product to send a file to, which is why the promise is checkable rather than something you have to take on trust: open your browser's network panel and watch it do the work without making a request.
Is there a size limit, or a limit on how many files?
None that we impose. The limit is your own machine's memory, because that is where the work happens — a few hundred megabytes is comfortable on a laptop, and less on a phone. There is no daily task counter, no queue and no account.
What does it cost, and what is the catch?
Nothing, and there is no paid tier that unlocks features: the whole product is the free one. That is affordable because running it costs us nothing — your computer does the work — so there is no per-file cost to recover, no advertising and no data to sell.
