Watermark PDF
Type the word to overlay — “DRAFT”, “CONFIDENTIAL”, the name of whoever receives the document — and choose how it should look. The PDF never leaves your device.
Your file stays on your device: nothing is uploaded
How it works
The text is drawn on top of the content of every selected page, like a stamp: the text and images that were there stay untouched underneath, and the document stays searchable and selectable. The watermark adapts to the shape of each page, one by one — a document mixing portrait and landscape pages gets a correctly sized mark on each — and it accounts for rotated pages, which is where these tools most often go wrong: on a page turned 90 degrees the mark appears upright like on the others, not lying on its side. You can limit it to some pages by writing ranges, for example 1-3, 7, 10- where the trailing dash means “to the end”.
Your files are never uploaded. Anywhere.
Not to a server of ours, not to a third party, never. When you pick a file it stays in your browser’s memory: it is read, processed and written back on your device, and you save the result yourself. There is no path that takes it elsewhere, because there is no server to send it to.
