Image Watermark

1What is Image Watermark?

Protect your images with text or image watermarks.

Image Watermark is part of the Pixly suite of professional image tools. It runs entirely in your browser with no software to install, requires no design experience, and delivers results in seconds — whether you are processing one image or an entire batch. Every operation is applied on the full-quality decoded image, so the output preserves the fidelity of your original file.

2How does Image Watermark work?

The watermark engine renders your text into an anti-aliased raster at the size and color chosen, then composites it over the image with adjustable opacity. Text is drawn with a font hinting at screen sizes so it stays crisp, and the engine positions it in the corner or center you select with safe margins so it never touches the edge.

Opacity blending uses true alpha compositing, meaning the underlying image detail remains visible through the mark — the standard technique for copyright protection that does not ruin the photo.

6Who uses Image Watermark?

E-commerce teams process entire product catalogs to consistent sizes and weights, which measurably improves load speed and conversion. Content creators and social media managers depend on it for daily platform-ready assets, while students and office teams use it to shrink scans and photos so they fit comfortably inside emails, forms and presentations.
