Compress Images to JPEG XL — Smaller, Same Look
JPEG XL is the most efficient photo format that browsers finally support: typically 30–60% smaller than JPG at the same visual quality, with transparency and wide colour on top. This free JXL compressor converts your images to .jxl entirely in your browser — no uploads, and batch conversion with a single ZIP download.
Serious Savings
Real-world photos routinely shrink by a third to a half versus JPG at the same look — storage and bandwidth bills notice.
Your Quality Dial
One slider trades size for fidelity, and every result shows its exact saving versus the original — no guessing.
Batch Compress a Whole Folder
Drop in a mixed set of images — JPGs from a camera, PNG screenshots, iPhone HEICs — set one quality level, and download a single ZIP of JXL files.
