About the formats

JPEG XL

JPEG XL (JXL) is a next-generation format designed to replace JPEG, with both lossless and high-quality lossy modes and very fast decoding. Browser support is still limited (Safari leads), so it is best for archival and pipelines you control.

JPG

JPEG is the most universally supported image format in existence — every browser, app, device, and upload form accepts it. It uses lossy compression tuned for photographs. This converter encodes JPEG with MozJPEG, which squeezes out noticeably smaller files than standard encoders at the same visual quality.

Frequently asked questions

Are my JPEG XL files uploaded to a server?

No. The conversion runs entirely in your browser using WebAssembly codecs — your files never leave your device. After the first visit the converter even works offline.

Can I convert many files at once?

Yes — add as many files (or whole folders) as you like, convert them in one batch, and download everything as a single ZIP. There are no file-count or size limits.

Will I lose quality converting JPEG XL to JPG?

You stay in control: JPG quality is adjustable in the options panel, and the defaults are tuned to be visually indistinguishable for typical images. You can re-convert with different settings instantly.
