Format description

JPEG XL (or JXL) is a new image format with better compression than other image formats like legacy JPEG, PNG, WebP, AVIF and others. Designed for the modern web and with professional photography in mind, JPEG XL offers a more efficient way of storing images. In addition to supporting alpha channels/transparency, lossless, progressive loading and animations, the new image format promises high speed encoding and decoding even on phones.

JPEG XL has experimental support in Firefox, Chrome and other Chromium-based browsers like Edge. For now, you need to enable a feature flag for the browsers to display JXL images.

MConverter’s conversions from JPEG XL are lossless, so there is no reduction in the quality of your images.
When converting from JPG or GIF to JXL, the quality is mathematically lossless. In all other cases when converting to JXL, the image quality is kept visually lossless. Your images will look visually identical.

Common questions about JXL conversions

How to open a JXL file?

If you don't know how to view a JXL file, you can convert it to another format you already recognize. You can use MConverter for the conversion.

Can I convert JXL files in bulk?

Yes, MConverter supports batch converting of multiple JXL files at once. You can even drag and drop folders containing JXLs.
Pasting JXL files and folders copied in the clipboard also works: use Ctrl+V.

Can I convert a JXL file, if its size is 2 GB?

Yes, with MConverter Pro you can convert big JXLs, up to 2 gigabytes each.
The free version lets you convert files up to 100 MB. If you need to convert JXL files over 100 megabytes, try MConverter Pro. If your files aren’t over 1 GB, then you can use MConverter Plus instead, as it’s cheaper.

Is converting JXLs safe with MConverter?

Yes, we encrypt your connection using industry standards. Plus, your JXL files are only accessible by you. 4 hours after the conversion completes, they are automatically deleted from MConverter’s servers. You can also delete your JXLs and other converted files immediately after finishing the conversion by clicking the bin icon.

How long does it take to convert JXL?

I love this converter! It's free and easy to use, and it successfully converted .mov with transparent background to .png with transparent background in only a few seconds. It will now live permanently in my Tools bookmark folder :)

AMAZING APP! I am so glad I found it!! It actually converts WEBM files without the weird bleeds! It's the only app I use to convert cute emotes from any site! I have been looking for years to find an image/gif converter but all the ones I found didn't convert emotes correctly. MCONVERTER DOES!! Hands down, best app!

I tried several programs to convert AI files to PNG, but only this program managed to convert both the text and the image exactly as in the original. The other programs transformed the text using their own fonts, which were not the ones originally used.

An exceptional product, with a fantastic, simple, immediate effective UX. A spatial combination of which format can be converted to which other format. A fast and flawless execution, with a very high quality of the output that maintains practically all the characteristics of the original document.

This app is exactly what I asked for and is super easy to use. I am not a big time computer wizard so I need apps that do what they say do in a straightforward process. This app does just that! I love it and will continue to use it and will advise others of it as well. Good job to the owners/developers! And, sincere THANK YOU!

AMAZING! This is the perfect file converter! The first thing I used it for was to convert WMV files to MP4 and it worked flawlessly. I then realized it supports all kinds of formats and is basically unlimited. The UI is very user-friendly and super easy to navigate. Incredible app, MConverter!
