Frequently asked questions
Why can't I open my .jxl file?
JPEG XL is a modern image format adopted by browsers since late 2026, but most photo editors, viewers and office apps don't support it yet. Converting to JPG/PNG makes the image usable everywhere.
Are my .jxl files uploaded to your server?
No. Decoding happens inside your browser tab using WebAssembly. Your files never leave your device — it even works offline.
JPG or PNG output — which should I pick?
Pick JPG for photos: universally compatible and much smaller. Pick PNG when you need pixel-perfect quality, transparency, or plan further lossless editing.
Will converting reduce quality?
PNG output is fully lossless. JPG output applies light compression (quality 90) which is visually indistinguishable for photos while keeping files small.
