Convert Files to JXL or from JXL Online for Free

What is JXL Format?

JPEF XL, or JXL, is a new image format that the Joint Photographic Experts Group (JPEG) officially finalized in 2021. It was supposed to be the future of image compression. JXL files make use of advanced encoding techniques like modular transforms and context-adaptive entropy coding. They are able to preserve much more image detail and shrink file size by up to 30%-60% smaller than JPEG or PNG at equal quality.

Frequently Asked Questions

A JXL converter like AhaConvert is an online web application that converts JPEG XL (.jxl) images into formats like JPG, PNG, or WebP. Because not all devices and browsers support JXL at this point, a converter helps you open, share, and use those files in just seconds without any compatibility issues.

It’s simple and only takes three steps with AhaConvert:

  • Upload your .jxl image
  • Select the output format
  • Hit “Start Conversion”, wait a few seconds, and then download your new image in JPG/PNG.

The answer depends on your application. JXL provides excellent quality and compression balance, similar to AVIF. It supports more advanced features like HDR and lossless JPEG reconstruction. However, WebP and AVIF are currently better supported across browsers.

Yes, JPG or PNG can be converted back to JXL format with AhaConvert. The actual benefit, however, depends on the image type:

  • If your image was initially saved as JPEG, transforming it to JXL will not bring back the lost quality. The main benefit could be the smaller file sizes thanks to the JXL’s efficient encoding, although the visual outcome will remain the same.
  • If your image is lossless, like PNG, converting it to JXL can help you preserve full image quality with the file size significantly reduced. This is best for archiving, web optimization, and professional purposes.
