JPEG XL Image Format
Download free sample JXL (JPEG XL) files to test your image converters, browsers, and applications. JPEG XL is a next-generation image format offering superior compression and quality compared to JPEG, PNG, and WebP.
JPEG XL (.jxl) is a royalty-free, next-generation image format developed by the Joint Photographic Experts Group. It combines the best features of Google's PIK and Cloudinary's FLIF formats, offering exceptional compression efficiency while maintaining outstanding image quality.
JPEG XL supports both lossless and lossy compression, making it versatile for photography, web graphics, and archival purposes. The format achieves up to 60% smaller file sizes compared to traditional JPEG at equivalent visual quality, and outperforms WebP and AVIF in many scenarios.
Notable capabilities include progressive decoding for faster web loading, support for wide color gamuts (HDR), alpha transparency, animation, and image dimensions up to 1 billion pixels per side. JPEG XL also offers unique lossless JPEG recompression, allowing existing JPEG files to be converted to JXL with 20% size reduction and perfect reversibility.
While browser support is still growing, JPEG XL is fully supported in image editing software like GIMP, darktable, and ImageMagick. Safari has native support, and other browsers can enable it via flags or extensions. The format is ideal for photographers, web developers, and anyone seeking optimal image compression.
