Why Watermark Your Images?

In the era of AI image crawlers and rampant social media reposting, protecting your creative IP is more important than ever. By stamping your photography or digital artwork with a translucent copyright label, you deter unauthorized commercial reuse of your assets.

The Local Processing Advantage

Most watermarking websites require you to upload your pristine, unreleased high-resolution artwork to their backend servers. This immediately exposes your unwatermarked files to their data ingestion pipelines.

Our tool secures your artwork by leveraging native HTML5 CanvasRenderingContext2D. The text overlay is literally fused into the pixel grid locally on your computer. If you turn off your Wi-Fi, this tool will continue to function flawlessly.

What is Security Tile Mode?

A single watermark in the corner of a photo can be easily cropped out or removed using simple AI inpainting tools. Security Tile Mode mathematically tiles your text diagonally across the entire surface area of the image, making it virtually impossible for unauthorized users to cleanly strip the watermark without destroying the image.
