Microsoft is expanding Windows 11’s image-format horizons by introducing official JPEG XL (JXL) support through a system extension bundled with the 24H2 update. The move arrives as Apple already adopted JPEG XL with the iPhone 16 series, underscoring the format’s potential to deliver higher compression efficiency without sacrificing quality in royalty-free form. However, even with the extension available in the Microsoft Store for Windows 11, users should not expect immediate full-featured viewing in all first-party apps. Tests and early reports show that some core apps—most notably Photos and Paint—do not yet recognize or render JPEG XL images, highlighting the ongoing process of app ecosystem-wide support. The Windows 11 release notes and extension description indicate that the initial scope focuses on enabling thumbnail previews in File Explorer, setting JPEG XL images as desktop backgrounds, and opening JXL files in Windows Media Player Legacy, with broader app integration promised in future updates. This report provides a comprehensive, SEO-optimized look at what JPEG XL means for Windows 11 users, how the extension works today, practical workarounds, and what to expect as more Windows apps gain native support.
Background on JPEG XL: A royalty-free, efficient image format with broad potential
JPEG XL, often abbreviated as JXL, is positioned as a next-generation image format designed to improve compression efficiency while supporting advanced features that traditional formats struggle to deliver within a royalty-free framework. Unlike proprietary alternatives or formats with licensing complexities, JPEG XL emphasizes openness and broad adoption potential, which is particularly important for developer ecosystems, device manufacturers, and end users who handle large image libraries or require high-quality preview capabilities at reduced file sizes.
Key characteristics of JPEG XL include its ability to deliver high-quality still images at substantially smaller file sizes compared with legacy formats like JPEG, while offering lossless or near-lossless options for professional workflows. The format supports 8- and 16-bit color depth, alpha transparency, and progressive decoding, which allows applications to render a lower-quality preview quickly and gradually refine the image as more data is loaded. Additionally, JPEG XL’s design aims to preserve color fidelity, minimize color smearing, and maintain sharp boundaries, which is particularly valuable for photographers, graphic designers, and content creators who work with large image catalogs.
From a broader industry perspective, JPEG XL’s royalty-free model is a strong selling point for consumer electronics ecosystems and software developers alike. It reduces licensing friction for device makers embedding image capabilities into cameras, printers, embedded displays, and desktop software. The adoption of JPEG XL by a major platform like Windows 11 signals recognition of its long-term viability as an efficient, scalable image format capable of handling everything from thumbnails to high-resolution gallery views in a way that complements modern content workflows.
The current environment for image formats includes legacy standards such as JPEG and PNG, as well as newer formats like WebP and AVIF. Each format carries trade-offs between compression efficiency, decoding speed, quality at various bitrates, and ecosystem support. JPEG XL’s promise lies in delivering strong compression gains without sacrificing the ability to edit or view images in common applications, particularly as operating systems begin to provide native handling and as third-party tools integrate plugin-based support. The broader industry implications of JPEG XL adoption include faster gallery loading times, reduced storage requirements for vast image libraries, and smoother web experiences when browsers and apps can render JXL images efficiently. This context helps explain why Microsoft’s move to extend JXL support in Windows 11 is seen as a meaningful step toward mainstream adoption, even as the ecosystem at large ramps up full compatibility.
Windows 11 24H2 extension: what it adds, what it currently lacks, and how to access it
The 24H2 update for Windows 11 introduces a JPEG XL Image extension distributed through the Microsoft Store. The primary purpose of the extension at this stage is to lay the groundwork for JPEG XL support across the Windows experience. Functional aspects currently available include the ability to preview JPEG XL thumbnails in File Explorer, which helps users identify JXL files at a glance within folders and libraries. The extension also enables some basic interaction, such as setting a JXL image as a desktop background and opening JPEG XL images within Windows Media Player Legacy, providing at least a minimal pathway to view content stored in JXL format.
However, the most visible gap remains: first-party viewing and editing in the core Windows apps that drive day-to-day workflows. At the time of review, Photos and Paint—the two flagship image-handling applications on Windows 11—do not recognize or render JPEG XL images. This gap means that, despite having the extension installed, users cannot open JXL files directly in Photos or Paint, which are among the most frequently used tools for casual viewing and basic editing. The extension listing in the Microsoft Store explicitly notes that “Support for JPEG XL is coming to additional apps,” underscoring that broader integration is expected in future updates. This future-oriented statement signals that Microsoft intends to expand native support as developers update their apps to recognize the JXL format.
From an installation perspective, consumers can obtain the extension by visiting the Microsoft Store and downloading it for free. After installation, the user experience includes:
- Thumbnail previews: File Explorer displays small previews of JXL images, making it easier to manage and navigate large image libraries without fully opening each file.
- Desktop background usage: Users can set JXL images as wallpapers, integrating the format into everyday personalization workflows without conversion.
- Windows Media Player Legacy support: JPEG XL files can be opened using Windows Media Player Legacy, providing a fallback path for basic viewing through an established media interface.
- Limited app support: Currently, major Windows applications like Photos and Paint do not yet support JXL, which delays full integration into common editing pipelines.
It’s important to note that the extension’s capabilities are incremental rather than comprehensive at this stage. The user experience will vary depending on the specific Windows 11 build, the update channel (e.g., Release Preview), and the update cadence of first-party apps and third-party tools. Microsoft’s strategy appears to involve releasing a minimal viable feature set to begin ecosystem-level usability, then expanding compatibility as app developers adopt the format in their own update cycles. This staged approach aligns with how Windows typically rolls out new file formats or codecs: initial platform support with limited app compatibility, followed by broader adoption as developers update their software stacks.
For users who are curious about the practical steps, the installation and initial use flow is straightforward:
- Ensure your Windows 11 device is running the 24H2 update, ideally in the Release Preview channel or a corresponding testing environment where the extension is available.
- Open the Microsoft Store and search for the JPEG XL Image extension, then install it.
- After installation, verify that File Explorer shows thumbnails for JXL files and that a JXL image can be set as a desktop background.
- Attempt to open a JXL image with Windows Media Player Legacy to confirm basic viewing functionality.
- If Photos or Paint cannot open JXL files, use the thumbnail view in Explorer as a quick reference, or rely on Windows Media Player Legacy or third-party viewers until full app support is introduced.
These steps illustrate how Windows 11’s JPEG XL ecosystem currently functions: a partial but tangible improvement that begins to shift the user experience toward native handling, while still requiring broader app integration before JPEG XL becomes a seamless, all-in-one solution within the core image-editing and viewing suite of Windows.
Hands-on testing and observed behavior: what works now and what remains limited
Real-world testing of JPEG XL on Windows 11 with the 24H2 extension reveals a mixed picture that is typical for early-stage format support in a broad operating system ecosystem. The most immediately noticeable improvement is that Windows can display thumbnails for JPEG XL files in File Explorer. This thumbnail generation is essential for users who maintain large image libraries, as it provides quick visual cues about the content without the need to open each image. Thumbnails also facilitate more efficient file management, enabling faster scanning and organization of images stored on local disks or network drives.
In addition to thumbnails, the extension enables setting JXL images as desktop wallpapers. This is a tangible feature that allows users to experience the quality and compression characteristics of JPEG XL in a real-world, high-visibility context within the operating system’s user interface. The ability to designate a JXL image as a wallpaper helps demonstrate the practical upside of the format’s alternates to traditional formats when used for everyday tasks such as personalization.
When opening JPEG XL images through Windows Media Player Legacy, users can at least achieve basic viewing in an established media player. This capability provides a fallback path for those who want to preview JXL content without converting files or relying on third-party software. It is not a replacement for a true image editor or viewer, but it does confirm that the format is accessible through standard Windows media playback channels, which can be a critical uptake point for users who are less inclined to experiment with alternative tools.
The most glaring limitation remains: first-party image editing and viewing applications. Photos and Paint, which represent the default, widely used image workflow for many Windows users, do not yet recognize JPEG XL images. Without native support in these core apps, users cannot directly edit JXL images within the familiar environment of Photos or Paint. This limitation means that even though a subset of Windows 11 functionality is available through the extension, the end-to-end editing workflow that many users rely on—capturing, editing, and saving JPEG XL images within the same ecosystem—still requires workarounds or third-party tools.
Users who want to view or work with JPEG XL more fluidly on Windows 11 today have several practical options. One approach is to use IrfanView, a lightweight image viewer known for its speed and broad plugin ecosystem. IrfanView can open JPEG XL files when paired with the appropriate plugin, enabling fast viewing and basic navigation through JXL images. Another option is to leverage web-based or browser-based viewers, including extensions designed to render JPEG XL content in Chrome. These tools can help bridge the gap between Windows’ native capabilities and the demand for efficient JPEG XL viewing, especially on devices where app store ecosystems or hardware constraints limit the availability of robust desktop software with JXL support.
From a testing perspective, the combination of thumbnail support in File Explorer, wallpaper capabilities, and the Windows Media Player Legacy fallback demonstrates that JPEG XL is no longer a hypothetical option on Windows 11. It is, in fact, a usable format that can integrate with the OS at a layer that does not depend entirely on the immediate availability of native editing tools. The results suggest that Microsoft’s strategy is to bring basic compatibility first, then progressively extend the feature set by expanding app-level support. This approach is typical in large-scale OS ecosystems where user expectations for a streamlined experience clash with the realities of coordinating multiple software developers across the platform.
In the near term, users should anticipate continued updates that broaden JPEG XL support across Windows apps. As more developers adopt JPEG XL, it is likely that Photos and Paint will eventually gain the ability to view and edit JXL images directly. In the meantime, leveraging the extension for thumbnails, wallpapers, and Windows Media Player Legacy viewing, coupled with trusted third-party viewers like IrfanView, offers a practical path to adopt JPEG XL without sacrificing convenience or performance. The ecosystem’s evolution will depend on the pace at which developers implement native JXL support in their apps, as well as how quickly Windows updates extend the extension’s capabilities beyond the current scope.
