PDF Image Stamp — Free, No Upload, Browser-Based

Stamp a PNG or JPG logo, seal, or label onto every page of a PDF — choose from seven placement positions and three size presets, then adjust opacity to taste. All processing runs entirely in your browser using pdf-lib: your PDF and image files never leave your device and no account is needed. Download the stamped PDF in one click.

Cómo usar esta herramienta

1. Drop your PDF into the first upload area, then drop your PNG or JPG stamp image into the second upload area.
2. Pick a position (bottom-right, center, top-left, etc.), choose a stamp size, and drag the opacity slider to set transparency.
3. Click "Stamp PDF" and download the result — every page will carry your image stamp at the chosen position and opacity.
