GIF to JXL Converter

About JXL

JPEG XL (JXL) is a next-generation image format standardised by ISO/IEC in 2022, developed as a long-term replacement for JPEG. It achieves up to 60% smaller file sizes than JPEG at equivalent visual quality and typically 20–35% smaller than AVIF or WEBP in photographic content. It supports both lossy and lossless compression, 32-bit HDR, wide colour gamuts (P3, Rec. 2020), alpha transparency, and animation.

Browser adoption is growing rapidly: Safari 17+ (2023), Chrome 91+ (lossless/transparent sequences), and Firefox 128+ support JXL natively. Google Photos uses JXL for archival storage, and Apple adopted it as the preferred export format in several iCloud contexts.

When to convert to JXL: When targeting modern browsers and archival quality with minimum file size. Professional photographers and developers storing large image libraries benefit significantly from JXL's superior compression. For delivery to the broadest possible audience today, WEBP or AVIF retain wider compatibility.

When to convert from JXL: When you need to use a JXL image in software, a website, or a service that does not yet support JXL — converting to JPG or PNG gives universal compatibility with no quality loss for lossless JXL sources.
