Microsoft continuously improves Windows 11, aiming to make it the ultimate operating system. One of the latest additions, though quietly integrated, is support for the JPEG XL (.jxl) extension—a next-generation image format. However, this feature is currently disabled by default.
Thanks to findings from Windows Latest, we now know how to enable this hidden functionality in Windows 11 24H2. But before we dive into the activation process, let’s explore what JPEG XL is and why enabling it could be beneficial.
What is the JPEG XL format in Windows 11?
As you might guess, JPEG XL is an image format—but unlike traditional JPEG, it is free of copyright restrictions and offers superior image quality while maintaining high compression efficiency.
Unlike other modern formats like HEIC and WebP, JPEG XL was specifically designed to give photography professionals more control over their images. Its ability to retain high quality while optimizing file sizes makes it an appealing choice for professionals and casual users.
Apple has already embraced JPEG XL with support in the upcoming iPhone 16, making it a compelling alternative for high-quality image storage. Following suit, Microsoft has integrated support for JPEG XL into Windows 11—not as a built-in feature, but as an installable extension.
How to activate JPEG XL support in Windows 11?
As mentioned earlier, JPEG XL support is a hidden feature in Windows 11 because it’s disabled by default. To enable it, you’ll need to install an extension from the Microsoft Store.
To do this, simply:
- Open the Microsoft Store.
- Search for “JXL” or “JPEG XL”.
- Download and install the correct extension.
Keep in mind that this feature only works on Windows 11 version 24H2, so make sure your system is updated before trying to activate it.
Why should you activate the support for JPEG XL format?
The JPEG XL format is often considered the spiritual successor to JPEG, offering improved features while remaining easy to use. Unlike some modern formats, it doesn’t suffer from major compatibility issues or errors, making it a reliable choice for professionals and everyday users.
One of its biggest advantages is its superior compression efficiency, allowing users to save up to 75% in storage space without compromising image quality. Additionally, JPEG XL supports a wider color range and boasts faster encoding and decoding speeds compared to traditional JPEG.
According to tests conducted by Windows Latest, a JPEG XL file maintained the same quality as a standard JPEG but was up to 47.90% smaller in size—a significant improvement in efficiency.
However, Microsoft still has work to do in expanding JPEG XL support across Windows applications, such as the Photos app, to make it more widely accessible.
