Seashore is an image editor for Mac OS X that is based on the technology of GIMP, with a clean user interface (using Cocoa). Seashore uses GIMP's native file format, XCF, and has support for a handful of other graphics file formats, including full support for TIFF, PNG, and JPEG, and read-only support for BMP, PDF and GIF. Seashore offers a smaller number of features in comparison with GIMP, but it includes layers and alpha channel support, gradients and transparency effects, anti-aliased brushes, tablet support and plug-in filters.

Seashore version 2.3.2 was released in January 2019 and is considered to be Stable.[1]

The latest release is distributed via the Apple App Store.[2]

It has a smaller feature set than GIMP, but Seashore's purpose is to be an easy-to-use free software graphics editor that runs natively on Mac OS X. Seashore is written using the native Mac toolkit, Cocoa.

  • Full support for the XCF file format

  • Layers and layer merging effects

  • Arbitrary selection regions (i.e. through a lasso tool)
