Engineered for Performance

Superior Compression

Up to 60% smaller than JPEG at equivalent quality — outperforming WebP and PNG in almost every metric.

HDR & Wide Gamut

Support for Rec. 2020 and beyond. Double the visible light range of common formats. Display colors and highlights that other formats cannot represent.

Progressive Decoding

Progressive loading that feels instantaneous. Images refine their detail as data arrives, perfect for slow connections.

Universal Capabilities

Native support for animation, transparency, and layers. A single format to replace GIF, PNG, and JPEG.

Royalty-Free

Built by the ISO JPEG committee. No licensing fees, no patents, just an open standard for everyone.

Lossless Transcoding

Migrate your entire JPEG library to JXL without a single pixel of generation loss, and back again if needed.

Wide Color Spectrum

High Dynamic Range (HDR) can make the difference between a dull image and one that feels alive. JPEG XL preserves the full luminosity of the sun and the deepest detail in shadows simultaneously.

Wide Color Gamut unlocks colors that were previously uncapturable. From the electric neon of a city night to the subtle gradients of a tropical flower, JPEG XL covers over 75% of the visible spectrum. Other common formats cover less than 36% of what's visible.
