About PDF Watermark
Add a watermark to a PDF in your browser with this free stamp tool. Open a document, type a label or drop a PNG or JPG, then place it in the center or drag it to a custom spot. Rotation, opacity, font, size, and color stay under your control, and you can limit the mark to a page range. The file never leaves your device.
People stamp CONFIDENTIAL or DRAFT on a contract pack, a thesis, or a price list before they send it. Offices add a logo as a light image mark. Students label a draft so a copy is not mistaken for a final file. Templates fill common phrases so you do not retype them.
Choose a PDF within the size and page limits, set the watermark, preview a page, then download. Password protected files should be unlocked first. After stamping you can compress or add page numbers with the other PDF tools.
All stamping happens locally, so contracts and personal scans never leave the browser. Use this free PDF watermark tool, stamp PDF text utility, and image watermark converter whenever a document needs a private mark.
