How to add a watermark to a PDF
Upload your PDF, type the watermark text, adjust opacity/angle/size until it looks right, then download. The watermark is stamped once per page, centered.
A text watermark is the fastest way to mark a document's status at a glance — "DRAFT" before a report is finalized, "CONFIDENTIAL" before it's shared outside a team, or "SAMPLE" across a preview you're sending before the paid version. Because the watermark is drawn as real page content (not a floating overlay), it stays in place in every viewer, survives printing, and shows up in any image made from the page — so it does its job however the file ends up being viewed.
Is my PDF uploaded anywhere?
No — the watermark is stamped entirely in your browser. Your PDF stays with you — your eyes only, we never get a look.
Can I control how visible the watermark is?
Yes — adjust opacity, size, and rotation angle until it looks the way you want before downloading.
Does the watermark apply to every page?
Yes — the same watermark text is stamped once, centered, on every page of the PDF.
Why would I add a watermark to a PDF?
Common cases: marking a document "DRAFT" or "CONFIDENTIAL" before sharing it internally, stamping "SAMPLE" or "NOT FOR DISTRIBUTION" across a preview before selling a full version, or labeling a document with a status like "COPY" or "VOID" — anything where the text needs to be visible without covering up the underlying content.
Can I remove or change the watermark after downloading?
Not from this tool — once downloaded, the watermark is a permanent part of the PDF's content, the same as any other text stamped onto a page. To use a different watermark, start again from your original (unwatermarked) file.
Will the watermark print if someone prints the PDF?
Yes — the watermark is drawn as real content on the page, not an on-screen overlay, so it appears in print, in other PDF viewers, and if the pages are later converted to images.
