# Mask Editor

> Use this tool when you need to create custom masks for image processing by visually selecting areas of an image. The Mask Editor solves problems related to object isolation, image segmentation, and region-of-interest definition by generating black-and-white masks from user-painted selections. It takes image uploads as input and produces saveable masks as output, ideal for use in MCP client workflows.
