PNG to JPEG XL

Convert PNG to JPEG XL for dramatically smaller lossless files. JPEG XL keeps every pixel and transparency while cutting the size well below PNG. All in your browser.

✅

Much smaller than PNG, still fully lossless.

✅

Transparency is kept.

✅

Great for shrinking heavy graphics and screenshots.

Good to know

PNG is loved for being lossless, but it's also notoriously heavy — large screenshots and detailed graphics can balloon to several megabytes. Converting PNG to JPEG XL keeps the image perfectly lossless, including transparency, while typically cutting the file size dramatically. It's the easiest way to slim down a folder of PNGs without sacrificing a single pixel.

This matters for websites and storage: lighter lossless images load faster and take up less space (on a website, keep the PNG as a fallback for Edge and older browsers). The conversion runs entirely on your device with WebAssembly, so even confidential graphics or unreleased designs never touch a server. Drop a batch, keep Lossless ticked, and download smaller .jxl files in seconds.
