What is StampIt?
StampIt is a free browser-based batch watermarking tool. Add text or logo watermarks to multiple images at once using 9 position options (top-left, center, bottom-right, and more), adjustable opacity, and font size. For maximum protection, tiled filigrana mode repeats your watermark in a diagonal grid across the entire image- making it impossible to crop out.
StampIt supports SVG logos and text watermarks. All processing runs in the browser using the Canvas API- your images are never uploaded to any server. Download all watermarked images in a single ZIP archive.
How batch image watermarking works
StampIt uses the browser's native Canvas API to draw watermarks directly onto your images- no server, no upload. Drop your images, configure the watermark text or logo, choose a position and opacity, then hit apply. All images are processed concurrently.
The tiled mode repeats your watermark in a diagonal grid across the entire image at reduced opacity. This makes it virtually impossible to crop or clone-stamp the watermark out, giving you maximum copyright protection.
When should you watermark images?

- - When sending proofs to clients- they can preview but not use the full image
- - To brand a batch of product photos before publishing to a website or marketplace
- - To add a subtle logo or copyright to stock photos you sell online
