›How to use
  1. Drop a PDF (max 200 MB). The whole file is processed inside your browser and never uploaded.
  2. Choose watermark kind: Text (font size / colour / opacity / rotation, with optional diagonal tiling), Image (drop a PNG / JPG — typically a company logo), or off.
  3. (Optional) Enable Add page numbers and pick a format (N, N/total, Page N of total) and position.
  4. Hit Apply & download — the browser saves a new PDF with the watermark and/or page numbers stamped in.
Tips
  • Diagonal tiling is the standard anti-copy treatment for contracts, drafts and confidential docs — even a low-quality photocopy still shows the repeated CONFIDENTIAL — DO NOT SHARE pattern.
  • Image watermarks look best as a transparent-background PNG (your logo). 25-35% opacity is usually a sweet spot — visible without obscuring the text.
  • Page numbers start from page 1 in all three formats. To skip a cover, edit pages first with the PDF page editor.
  • vs ilovepdf / smallpdf — they upload your file to the cloud first; we process it 100% in your browser, suitable for contracts and confidential documents.
