ShareX 20.0.2 Launches With ARM64 and New Editor

ShareX, the widely popular open-source screenshot and screen recording tool for Windows, has officially released version 20.0.2 with significant platform and interface upgrades. The update introduces native ARM64 support through the Microsoft Store and a completely rebuilt image editor powered by Avalonia UI, marking one of the most substantial updates the project has seen in recent memory.

This release positions ShareX to remain competitive in an increasingly crowded productivity tool landscape, where alternatives like Snagit, Greenshot, and built-in Windows Snipping Tool continue to evolve. For the millions of users who rely on ShareX daily for content creation, bug reporting, and workflow automation, these changes represent a meaningful leap forward.

Key Takeaways From ShareX 20.0.2

• Native ARM64 support added via Microsoft Store, enabling full performance on ARM-based Windows devices like Surface Pro X and Snapdragon-powered laptops
• New image editor built on Avalonia UI framework delivers a modernized interface and improved editing experience
• Continued support for 80+ upload destinations including cloud storage, image hosting, and file sharing services
• The update reinforces ShareX's position as the most feature-rich free screenshot tool available on Windows
• Open-source development continues at a steady pace on GitHub, with active community contributions
• Compatibility improvements ensure smoother operation across the latest Windows 11 builds

ARM64 Support Opens the Door to Next-Gen Windows Hardware

The addition of native ARM64 support is arguably the headline feature of ShareX 20.0.2. As Microsoft and Qualcomm push aggressively into the ARM-based PC market with devices powered by the Snapdragon X Elite and Snapdragon X Plus processors, software compatibility has become a critical concern for users making the switch from traditional x86 hardware.

Previously, ShareX could run on ARM devices only through Microsoft's x86 emulation layer, which introduced performance overhead and occasional compatibility issues. With native ARM64 binaries now available through the Microsoft Store, users on devices like the Surface Pro 11, Lenovo Yoga Slim 7x, and Samsung Galaxy Book4 Edge can expect snappier performance, lower battery consumption, and a more reliable experience overall.

This move mirrors a broader industry trend. Major productivity applications including Adobe Photoshop, DaVinci Resolve, and various developer tools have already shipped ARM64 versions. ShareX joining this list signals that even community-driven open-source projects recognize the importance of ARM readiness as the Windows ecosystem transitions toward this architecture.

Avalonia UI Powers a Modernized Image Editor

The second major highlight of this release is the introduction of a completely new image editor built on the Avalonia UI framework. Avalonia is a cross-platform .NET UI framework that has gained significant traction in the developer community for its ability to deliver modern, responsive interfaces across multiple operating systems.

For ShareX, this means the image editor — one of the tool's most frequently used components — now features a cleaner, more contemporary design language. Users who annotate screenshots for bug reports, tutorials, or social media content will benefit from:

• A refreshed visual interface that aligns with modern Windows 11 design principles
• Improved rendering performance, particularly on high-DPI and multi-monitor setups
• Better scalability and responsiveness when working with large images
• A foundation that enables future cross-platform possibilities, though ShareX currently remains Windows-only

The choice of Avalonia UI is particularly interesting from a technical standpoint. Unlike WPF (Windows Presentation Foundation), which ties applications to the Windows platform, Avalonia is designed to work across Windows, macOS, and Linux. While the ShareX team has not announced any plans for a macOS or Linux release, the architectural decision to adopt Avalonia leaves that door open for the future.

Why ShareX Remains the Gold Standard for Free Screen Capture

In a market where Microsoft has steadily improved its built-in Snipping Tool — adding features like screen recording, text extraction via OCR, and annotation capabilities — ShareX continues to differentiate itself through sheer breadth of functionality.

ShareX offers a feature set that rivals and often exceeds paid alternatives costing $50 or more. Its capabilities include full-screen, region, window, and scrolling capture modes, as well as GIF and video recording. The tool supports automated workflows through customizable after-capture tasks, which can automatically add watermarks, resize images, upload to cloud services, and copy shareable links to the clipboard — all without manual intervention.

The upload functionality alone sets ShareX apart. With support for over 80 destination services — including Imgur, Google Drive, Dropbox, Amazon S3, FTP servers, and custom HTTP uploaders — ShareX provides a level of integration flexibility that no other free tool can match. For developers and IT professionals who need to quickly share screenshots in Slack channels, Jira tickets, or documentation platforms, this capability is invaluable.

Compared to Snagit, which costs $62.99 for a perpetual license, ShareX delivers comparable annotation and capture features at zero cost. The tradeoff has traditionally been a steeper learning curve and a less polished interface — a gap that the new Avalonia-based editor aims to narrow significantly.

The Broader Context: Open-Source Productivity Tools Gain Momentum

ShareX's continued development reflects a larger trend in the open-source software ecosystem. Productivity tools that were once considered niche alternatives to commercial products have matured to the point where they serve as primary tools for millions of professionals worldwide.

Projects like OBS Studio for streaming and recording, GIMP for image editing, and Blender for 3D modeling have demonstrated that open-source development can produce software that competes with — and sometimes surpasses — commercial offerings. ShareX fits squarely in this category, offering professional-grade screen capture capabilities backed by an active development community.

The project's GitHub repository remains highly active, with regular commits and community engagement. This sustained development pace gives users confidence that ShareX will continue to evolve alongside the Windows platform, adapting to new hardware architectures, display technologies, and workflow requirements.

What This Means for Users and Content Creators

For everyday users, the practical implications of ShareX 20.0.2 are straightforward. Those running ARM-based Windows devices can now use ShareX without the performance penalties associated with emulation. Content creators and technical writers who rely heavily on the image editor will find their annotation workflows smoother and more visually consistent with the rest of their Windows 11 experience.

For teams and organizations, ShareX's continued free availability and open-source nature make it an attractive option for standardizing screenshot workflows without incurring per-seat licensing costs. Key benefits for professional environments include:

• Zero licensing costs regardless of team size
• Customizable hotkeys and workflows that adapt to specific team needs
• Self-hosted upload destinations for organizations with strict data governance requirements
• Portable mode for use on shared or locked-down workstations
• Extensive automation capabilities that reduce repetitive manual steps

Developers who contribute to documentation, file bug reports with visual evidence, or create tutorial content will find ShareX 20.0.2 a worthwhile upgrade, particularly if they have recently transitioned to ARM hardware.

Looking Ahead: What's Next for ShareX

The adoption of Avalonia UI hints at potentially ambitious plans for ShareX's future. While the development team has not publicly committed to a cross-platform roadmap, the architectural foundation is now in place to explore macOS and Linux support — something the community has requested for years.

Additionally, as AI-powered features become standard in productivity tools — Microsoft's Snipping Tool now includes OCR text extraction, and tools like CleanShot X on macOS offer AI-enhanced editing — it will be interesting to see whether ShareX integrates similar capabilities. The open-source nature of the project means that community contributors could potentially add features like AI-powered redaction, automatic annotation suggestions, or intelligent region detection.

For now, ShareX 20.0.2 is available for download from the official website, GitHub releases page, and the Microsoft Store. Users on ARM64 devices are encouraged to install via the Microsoft Store to take advantage of the native binary. The update is free, as always, and existing users can upgrade through the application's built-in update mechanism.

ShareX 20.0.2 may not be a revolutionary release, but it demonstrates the kind of steady, meaningful progress that keeps open-source tools relevant in an increasingly competitive landscape. With ARM64 support and a modernized editor, ShareX is well-positioned to serve its user base for years to come.
