FAQ
Which image formats are supported?
PNG and JPG are supported. PNG is recommended for logos or signatures with transparent backgrounds.
Is my PDF uploaded to a server?
No. All processing is done entirely in your browser using pdf-lib. Your files never leave your device.
Can I stamp only specific pages?
This tool stamps every page. For per-page control, a more advanced PDF editor would be needed.
