Add text watermarks to PDFs
Mark drafts, internal documents or sample files with text such as CONFIDENTIAL, DRAFT or SAMPLE. You can watermark every page or only a selected range.
The watermark is added directly to the PDF pages in your browser. For highly sensitive legal or security workflows, review the downloaded result before relying on the watermark as a protection mechanism.
FAQ
Can I change watermark transparency?
Yes. Lower opacity values create a lighter watermark.
Does a watermark prevent copying?
No. A visible watermark is a visual label, not encryption or copy protection.
