Why watermark a PDF
Watermarks communicate document status such as CONFIDENTIAL or DRAFT and add a visible label to shared files. They do not prevent redistribution.
The watermark is drawn over existing page content at adjustable opacity. Review the result to ensure important text remains readable.
Watermark settings
Enter your watermark text, then adjust font size, opacity, and rotation angle. A lower opacity keeps the document readable while still marking every page.
Enable Repeat watermark to stamp text diagonally across the entire page. Use the Pages field to watermark only specific pages.
Before you watermark
Keep a clean copy of the original PDF. Watermarks are difficult to remove once embedded.
Use Protect PDF when an opening password is required; watermarking alone does not restrict access.
Mark review status without obscuring the evidence
For a six-page proposal whose cover should remain clean, enter 2-6 in Pages and use DRAFT with low opacity. Start with a single mark if repeated text would cross tables or diagrams; inspect a dense page before deciding to repeat it.
The repeat option places a three-by-three pattern on each selected page. It does not intelligently avoid text, and long wording can extend beyond page edges. A short label is easier to place than a sentence.
Check the mark and its limits
Reopen the download and verify that the cover is unmarked, all selected pages carry the intended word, and small table values remain readable. If a label is clipped, shorten it or reduce font size and retry from the clean original.
A watermark communicates status; it does not restrict access, stop copying, establish ownership, or hide sensitive content. It is drawn over the page, so underlying content remains. For access restrictions use password protection, and for confidential details use an appropriate redaction workflow.
