About JPEG XL Format
JPEG XL (JXL) is a next-generation image format designed to replace both JPEG and PNG. It offers superior compression with both lossy and lossless modes, progressive decoding, HDR support, and wide color gamut. JXL can also losslessly transcode existing JPEG files to smaller sizes. For web use with broader browser support, consider our WebP converters or AVIF converters as alternatives.
Superior Compression
60% smaller than JPEG at same quality
Lossless Mode
Perfect quality preservation option
JPEG Transcoding
Lossless recompression of JPEG files
HDR Support
High dynamic range and wide gamut
Why Use JPEG XL?
Save Storage Space
JXL offers 30-60% smaller files than JPEG with equal or better quality. Use our JPG to JXL converter to reduce your photo archive size dramatically.
Preserve Original JPEGs
JXL can losslessly recompress JPEG files and restore them perfectly. Your JPG to JXL conversions are fully reversible.
Replace PNG Files
JXL lossless mode beats PNG compression by 30-50%. Convert with our PNG to JXL converter for smaller files with identical quality.
Future-Proof Format
JXL is designed for the future with HDR, wide gamut, and progressive decoding. Use our image converters for compatibility needs.
Frequently Asked Questions
JPEG XL is a modern image format developed by the JPEG committee as the successor to JPEG. It combines the best features of existing formats: superior compression, lossless and lossy modes, animation support, HDR, and progressive decoding. The format is designed to eventually replace both JPEG and PNG.
JXL often achieves better compression than WebP and comparable compression to AVIF, while offering unique features like lossless JPEG transcoding. However, browser support for JXL is still growing. For maximum compatibility, consider using our WebP or AVIF converters as alternatives.
Yes! When you convert a JPEG to JXL using lossless JPEG transcoding, the original JPEG can be perfectly reconstructed. This is a unique feature of JXL. Use our JXL to JPG converter to restore the original file.
Currently, Safari (iOS 17+, macOS Sonoma+) supports JXL natively. Other browsers like Chrome and Firefox have experimental support that can be enabled via flags. For broader web compatibility, use our JXL to WebP or JXL to PNG converters.
JXL typically achieves 30-60% smaller file sizes than JPEG at the same visual quality. For lossless compression of PNG files, JXL is usually 30-50% smaller. Use our JXL compressor to optimize file sizes further.
Yes, JXL fully supports alpha channels for transparency, making it suitable for replacing both JPEG and PNG files. Convert transparent images with our PNG to JXL converter to maintain transparency with better compression.
JXL conversion currently requires server-side processing due to the computational complexity. Your files are processed securely and deleted immediately after conversion. For simpler formats, many of our tools like the PNG to JPG converter run entirely in your browser.
