Add a watermark to a PDF
Stamp text across every page, with the opacity, angle and size under your control. The usual reasons are marking a document as a draft, as confidential, or as a copy that should not be circulated.
How to add a watermark to a PDF
- 1Open the PDF and type your textA preview shows the watermark over your actual first page.
- 2Set opacity, rotation and sizeDiagonal at low opacity is the convention for a reason: readable enough to notice, faint enough to read through.
- 3Apply to every pageThe watermark is drawn into the page content rather than added as an annotation, so it cannot be toggled off in a reader.
Questions
Are my files uploaded to a server?
No. The file is read by your browser and processed in the page. It never reaches a server, so there is no upload to wait for, no queue, and no copy of your document sitting somewhere with a retention policy.
Can the watermark be removed by someone else?
Not by clicking it off. It is drawn into the page content, not attached as an annotation layer. Anyone determined enough can still edit a PDF, so treat it as a marking rather than a lock.
Can I use an image as the watermark?
This tool does text only. For an image, place it on the page in an editor before running the file through here.
Does it go on every page?
Yes, with the same text, position and opacity throughout the document.
