JXL

JPEG XL image

JPEG XL (.jxl) is a modern raster image format designed to provide superior compression, wide color gamuts, and high-resolution support for web and professional use.

What is JPEG XL image?

JPEG XL is an image compression standard standardized by ISO and initially developed by the Joint Photographic Experts Group (JPEG). It is designed to outperform legacy formats like JPEG and PNG by offering better compression ratios, lossless and lossy modes, animation support, and progressive rendering. ConvertX allows you to easily convert between JXL and common formats like PNG or JPG using tools such as jxl-to-png, png-to-jxl, and jpg-to-jxl.

Advantages

Significantly smaller file sizes than JPEG at comparable visual quality
Supports both lossless and lossy compression
Handles high bit depths, wide color gamuts, and HDR
Supports animation and transparency
Built-in progressive decoding for slow networks

Limitations

Limited native support in older browsers and image viewers
Slower encoding and decoding speeds in some software implementations compared to legacy formats

How to open JPEG XL image files
