Patchy Open-Source Image Editor Focuses on PSD Compatibility and Familiar Workflows

Patchy is a free, open-source image editor designed for Windows, macOS, Linux, and web browsers, with a focus on game art, pixel art, and Adobe Photoshop file compatibility. According to the project documentation, it aims to keep text, vectors, masks, layer styles, and Smart Objects editable in layered PSD files while offering workflows and keyboard shortcuts familiar to Photoshop users.

Core Features and Format Support

• Cross-Platform Availability: Runs on Windows, macOS, Linux, and in local browser sessions via WebAssembly.
• File Compatibility: Opens and handles artwork from formats such as PDF, Affinity, Krita, GIMP, OpenRaster, and Paint.NET.
• Extensibility: Supports classic plug-ins and JavaScript scripting.
• Color and Editing Limits: Editing is performed in RGB at 8, 16, or 32 bits per channel, though the browser build is limited to 16 bits. CMYK is supported for proofing and exporting, while Lab and other color modes convert to RGB upon opening.

Practical Implications and Verification

The software contains no telemetry or tracking by default, with optional update checks and AI tool calls requiring explicit user action or API keys. Independent test results from October 2026 evaluated PSD compatibility using specific benchmark collections, noting perceptual render matches and text preservation scores under test conditions. Users can verify release authenticity through GPG signatures on Linux Flatpak repositories, code-signed Windows builds, and SHA-256 checksums published on GitHub.
