JXL to JPG Converter
Convert JPEG XL (JXL) files to JPG right in your browser. Free, unlimited batch, and your photos never leave your device.
Your files never leave your device — conversion runs locally in your browser.
To convert JXL to JPG, drop your JPEG XL files above — they are decoded with a WebAssembly build of libjxl right in your browser, never uploaded. This page is decode-only: it reads .jxl files most software can't open yet, but it doesn't create them. Batch is unlimited, and EXIF can be kept in the JPG.
Honest limits
- Decode only — reads JXL and writes JPG; it can't create .jxl files.
- HDR JPEG XL decodes to standard 8-bit SDR.
Need more than a browser can do? Desktop browsers go further than phones — and Media Moana converts at scale on hosted infrastructure.
How it works
Drop your files
Drag JXL files into the drop zone, click to browse, or paste from the clipboard. Whole folders work too.
Convert locally
Each file is decoded and re-encoded to JPG right in your browser — no upload, no queue. Adjust quality or size first if you like.
Download
Save converted files one by one, or download the whole batch as a ZIP. Originals stay untouched on your device.
About the formats
JXL — JPEG XL
JPEG XL (.jxl) is the next-generation successor to JPEG, offering about 60% smaller files at equivalent quality, lossless recompression of existing JPEGs, HDR, and progressive decoding. Apple added JPEG XL support across iOS 17 and macOS, and adoption is growing — but most tools still can't open it, making conversion to JPG the practical bridge.
JPG — JPEG
JPEG (.jpg) is the most universally supported image format in existence. Every browser, OS, app, printer, government form and photo lab accepts it. It uses lossy compression tuned for photographs, supports EXIF metadata, and at quality 85–95 is visually indistinguishable from the source for most photos — the safe default whenever compatibility matters.
Frequently asked questions
Is this safe? Do my photos get uploaded?
No upload happens — ever. Converting JXL to JPG runs entirely inside your browser using WebAssembly. Your files never leave your device, nothing is stored on any server, and the tool even keeps working if you go offline after the page loads. That's also why there are no file size limits, no queues and no sign-up.
Does converting JXL to JPG lose quality?
JPG uses lossy compression, so technically yes — but at the default quality setting the difference is invisible for normal viewing and printing. You control the quality slider: higher values mean larger, more faithful files. Your original JXL files are never modified.
Can I convert multiple JXL files at once?
Yes — drop in as many files as you like. Because conversion happens on your own computer instead of a server, there is no per-file fee, no daily cap and no waiting in line. Files are processed one after another, and you can download each JPG file as it finishes or grab the whole batch as a single ZIP.
Can this tool convert images to JXL?
No — this page is decode-only: it opens .jxl files that most software can't read yet and writes universally supported JPGs. Browser-side JPEG XL encoders aren't mature enough to ship, so rather than promise something slow and flaky, we don't. To create JXL files, use the official cjxl tool on a desktop.
Is there a file size or quantity limit?
There is no hard limit. Server-based converters cap uploads because your files consume their bandwidth and CPU; here converting JXL to JPG happens on your machine, so the only practical limit is your device's memory. Desktop browsers comfortably handle very large files and big batches.
