A new interactive demo page showcases JPEG XL capabilities, letting developers test the next-generation image format directly in their browser. The page, hosted on Tildeweb, presents side-by-side comparisons and technical details, offering a practical look at how the format performs with real-world images and compression settings.

JPEG XL aims to replace older formats like JPEG and PNG with better compression, lossless editing, and progressive decoding. While browser adoption remains limited, this demo provides a tangible tool for developers and designers to evaluate its potential for web performance and archival use, bypassing the need for local software.

The format's future hinges on broader browser support and industry buy-in. This demo serves as an advocacy tool, giving the community a hands-on reference point. For developers, it's a chance to test workflows and assess trade-offs before committing to a new image pipeline.
