Everything you need in a free PDF watermark tool
Stamp an image on every page
Overlay a logo, signature, seal, or brand mark on your PDF with position, size, opacity, and rotation controls.
Corner, center, or tiled
Place the stamp in a corner or the center, or tile it diagonally across each page for a classic watermark look.
Keeps PDF text selectable
The original pages stay intact — only the image is drawn on top. Text, links, and layout are preserved.
100% browser-based
Stamping runs with pdf-lib in your browser. Your documents and images stay on your device — nothing is uploaded to Focera.
How It Works
Adding a watermark should be quick and private. Focera keeps the whole flow on one page — upload your PDF, choose a stamp image, set placement, and download without an account or desktop installer.
- Upload your PDF. Drag and drop a file up to 25 MB (max 50 pages), or click the zone to browse from your device.
- Add a stamp image. Use a PNG for transparent logos, or JPG/WebP. Set position, size, opacity, and optional diagonal rotation.
- Stamp and download. The image is drawn on every page locally. Preview the result and download again anytime.
Jump back to the PDF watermark tool anytime to process another file.
Popular Use Cases
- Brand documents — Add your logo to proposals, reports, and pitch decks before sharing.
- Draft and confidential marks — Stamp a translucent “DRAFT” or “CONFIDENTIAL” graphic across pages.
- Signatures and seals — Place a signature PNG or company seal in a corner of contracts and letters.
- Proof and sample files — Tile a watermark so shared PDFs stay clearly marked as samples.
Private by Design
Your PDF and stamp image are read and processed entirely in your browser. Focera does not receive the files, store pages, or run stamping on a remote server. When you leave the page, temporary previews are revoked and nothing remains on our infrastructure.
