About JXL and PNG
JXL: JPEG XL (.jxl) is a new image format that compresses better than JPG and can repack JPGs losslessly.
PNG: PNG is a lossless image format with transparency, ideal for screenshots, logos and graphics.
Questions
Is my JXL file uploaded?
No. The conversion runs inside this browser tab, and the PNG is created on your device. Nothing is sent to a server.
Can I convert several JXL files at once?
Yes. Drop as many as you like, a folder or a ZIP; “Download all” saves every PNG in one ZIP.
