About JPEG XL Format

JPEG XL (JXL) is the next-generation image format designed to replace JPEG. Developed by the JPEG committee, it offers superior compression, true lossless mode, and can even losslessly transcode existing JPEG files to save ~20% without any quality loss.

Why Convert to JPEG XL?

Superior Compression

JPEG XL achieves up to 60% smaller file sizes compared to JPEG at equivalent visual quality.

True Lossless Mode

Distance 0 provides mathematically identical output - no data is lost during conversion.

HDR Support

Native support for HDR, wide color gamut, and high bit-depth images up to 32-bit.

Progressive Loading

Images can be progressively decoded, showing a preview before fully loaded.

Frequently Asked Questions

Safari 17+ has native JXL support. Chrome and Edge can enable support via flags. Firefox support is in development. For wider compatibility, consider also having WebP or AVIF versions.

Distance controls quality: 0 = mathematically lossless (identical to original), 1 = visually lossless (imperceptible differences), 2-3 = higher compression with slight quality reduction. Most users should use 1 for best balance.

Yes! If you use distance 0 (lossless mode), you can reconstruct the exact original JPEG file. This is unique to JPEG XL and allows reversible compression.

At distance 1 (visually lossless), expect 40-60% smaller files. Even lossless mode (distance 0) typically saves 20% through more efficient encoding of existing JPEG data.

Effort (1-9) controls encoding speed vs file size. Higher effort takes longer but produces smaller files. For most users, effort 7 offers a good balance between speed and compression.
