The Photopea Editor plugin integrates the online image editor Photopea into Obsidian, enabling users to edit PNG and JPG images directly within the app. By replacing the default image viewer with an embedded Photopea interface, it streamlines the image editing process without disrupting the Obsidian workspace. Users can make edits, save changes, and re-import images into their vault manually. The plugin supports seamless editing for PNG, JPG, and JPEG formats, and plans to expand its capabilities with automated saving and additional format support in the future.
