# Convert JXL to JPG.

> JXL opened and saved as JPG — right on your own device.

Convert JPEG XL images to universal JPG entirely in your browser — **decoded by libjxl compiled to WebAssembly, running on your own device**. JXL is a great archive format that most software still cannot open; JPG opens everywhere. 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.

## Why convert out of JXL

JPEG XL compresses beautifully, but support outside Safari is still thin — Chrome dropped its experiment, and most editors, viewers and upload forms simply refuse .jxl files. Converting to JPG trades some bytes for universal compatibility: mail clients, CMSes, office suites, everything opens it. Keep the JXL originals as masters; this tool produces the copies the rest of the world can read.

## Quality choices that matter

JPG is lossy, so the quality slider decides how faithful the copy is — the default is visually transparent for photos. Need the opposite direction? [JPG to JXL](https://compress-pro.com/jpg-to-jxl) writes new JPEG XL files, and [Compress JXL](https://compress-pro.com/compress-jxl) re-squeezes existing ones without leaving the format.

## Frequently asked questions

### Why won’t my JXL files open anywhere?

Browser and OS support stalled — Safari renders JXL, Chrome and most editors do not. That is exactly what this converter is for: the JPG copy opens everywhere.

### Do both JXL container flavors work?

Yes — bare codestreams and ISO-container .jxl files are both detected by content and decoded the same way.

### Is quality lost in the conversion?

JPG re-encoding is lossy by nature — at the default quality the difference is not visible for photos. Raise the slider to 100 for the most faithful copy.

### Are my images uploaded?

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.
