Protect your documents by adding a diagonal text watermark to every page. Commonly used for marking documents as "CONFIDENTIAL," "DRAFT," "SAMPLE," or adding a company name. The watermark appears on every page at a semi-transparent opacity.
Upload your PDF, type your watermark text, and click "Add Watermark." The text is stamped diagonally across every page at 30% opacity in a large font, visible but not overwhelming.
Can I remove a watermark after adding it? No — watermarks are permanently added to the PDF. Always keep a copy of the original file.
Can I change the watermark color or position? Currently the watermark is a fixed light gray at 45° across the center of each page.
