About Add Watermark
Stamp a watermark across every page to mark a document as a draft, confidential, or branded before you send it out. It takes a few seconds and doesn't require editing the PDF by hand.
How to add watermark
- 1Upload the PDF you want to stamp.
- 2Type the watermark text, such as "DRAFT", "CONFIDENTIAL", or your company name.
- 3Adjust the position, size, rotation, and opacity so it's visible without covering important text.
- 4Preview the result on the page thumbnails and adjust until it looks right.
- 5Run the watermark and download the stamped PDF.
Tips
Lower the opacity to around 20-30% for a subtle watermark that doesn't obscure text — useful for a "CONFIDENTIAL" stamp on a document people still need to read.
A diagonal watermark across the page is harder to crop out than one placed in a corner.
For a draft under review, wording like "DRAFT — NOT FOR DISTRIBUTION" removes any ambiguity about the document's status.
