How to watermark a PDF
- Attach the PDF, then choose text watermarking or Image watermark. Use Attach Watermark Image for an image mark.
- Set content or image width, Pages, Position, Edge Margin, Rotation and Opacity. Review the page-one preview.
- Choose Apply Watermark, download the watermarked PDF and check every page range you selected.
Common watermark uses
Watermarks can identify a document as Draft, Confidential, Sample or Copy. A company logo can also add consistent branding to reports and handouts.
Use opacity carefully
A watermark should be visible without making the underlying document difficult to read. Test busy and sparse pages because the same opacity can look different across a document.
Make the mark readable without hiding the document
A large diagonal Draft label may work on a spacious report but obscure a dense invoice. Start with moderate opacity and check the busiest page, not just an empty cover. When using a logo, choose an image with suitable contrast and avoid enlarging a small source beyond its useful resolution. Rotation and size affect how much space the mark occupies near the page edges.
The preview shows page one. If your Pages setting excludes that page, the export still follows the selected range; inspect the downloaded result to confirm the placement there. Watermarking adds a visual mark, not encryption, redaction or a guarantee against copying. A Confidential label does not prevent the recipient from reading or forwarding the document. Keep the original so you can make a clean version without stacking another mark over a previous export.
