About
Patchy is a local image editor for layered PSD and PSB files, with workflows familiar to Photoshop users. It aims to keep text, vector shapes, masks, layer styles, and Smart Objects editable when opening layered projects.
It includes non-destructive adjustment layers and Smart Filters, brushes and retouching tools, path and vector editing, rich text, selections, Camera Raw development, and export to common image formats. Desktop builds are available for Windows, macOS, and Linux, with a browser build for modern browsers. Desktop versions have more memory available and add printing, scanner and camera import, and command-line automation.
Patchy processes images locally. The project says it does not use telemetry, tracking, or upload images. The browser build runs through WebAssembly, and some features and limits differ from desktop.
Patchy is an independent, open-source project released under the MIT license. It is not affiliated with or endorsed by Adobe.
