# Convert JPG to JXL.

> JPG to JPEG XL on your device — smaller, nothing uploaded.

Convert JPG photos to JPEG XL entirely in your browser — **encoded by libjxl on your own device, typically 20–40% smaller at the same visual quality**. The format built to replace JPG, applied to your existing photos. Nothing is uploaded.

**No uploads · No ads · Free & open source.**

## How it works

1. Drop files anywhere on the page, click to browse, or paste with Ctrl/⌘ + V.
2. Pick a quality or preset — or set an exact target size and let the tool find it.
3. Compress, compare before/after, and download — individually or as a ZIP.

## What JPEG XL buys you

JXL is the newest of the next-generation image formats — modern entropy coding, wider color, progressive decode, and file sizes that undercut JPG substantially at equal quality. For photo archives that compounds into real disk savings. The catch is support: Safari displays JXL natively, Chrome currently does not — which is why this site treats JXL as a storage and archival format rather than a web-delivery one.

## Archive honestly

Converting a JPG to JXL cannot restore detail the JPG already discarded — it re-encodes what is there into fewer bytes. For a web-ready format with broad support today, [JPG to AVIF](https://compress-pro.com/jpg-to-avif) is the better pick; for coming back out, [JXL to JPG](https://compress-pro.com/jxl-to-jpg) reverses the trip.

## Frequently asked questions

### How much smaller do files get?

Typically 20–40% below the source JPG at matching visual quality, more at lower quality settings. Target-size mode works too — type a cap and the encoder searches out the best fit.

### Will the .jxl files open on my machine?

Safari and a growing set of image tools read JXL; Chrome and most editors still do not. Treat it as an archive format and keep this converter handy for the way back.

### Is EXIF metadata kept?

No — JXL output is written without EXIF, GPS or camera metadata. If keeping metadata matters, convert to WebP instead, where the keep-metadata option applies.

### Is it private?

Yes. The conversion happens entirely on your device — the image is read, re-encoded and saved without ever touching a network. There is no server-side queue, no temporary copy in some bucket, nothing to expire or leak. Want proof? Run one file through, switch your connection off, and run another — it still works.
