Why PNG to JXL?
JPEG XL handles PNG-style content excellently—it supports transparency, lossless compression, and achieves much smaller files than PNG for the same quality.
For images with transparency, JXL typically produces files 50-70% smaller than PNG. It's particularly good at compressing screenshots, graphics, and illustrations.
Browser support is the main limitation. For web use today, consider WebP or AVIF. For archival and local use, JXL is the technically superior choice.
Frequently Asked Questions
Yes. JPEG XL fully supports alpha channel transparency, just like PNG.
