Midjourney deployed a web-based image editor in August 2024 that lets users modify AI-generated or uploaded images using AI-powered tools. Users can repaint specific areas of an image using text prompts (inpainting) or expand an image's canvas beyond its original borders (outpainting).

The Midjourney Image Editor (launched August 16, 2024 on midjourney.com) consolidates inpainting (called 'Vary Region,' which regenerates selected areas of an image guided by a text prompt), outpainting/canvas extension (extending the image boundaries and filling new space with AI-generated visuals), panning, zooming, and remixing into a single interface. A virtual brush tool replaced older square-selector and lasso tools for greater precision. The editor is available to users who have generated at least 10 images and is accessible only on the website, not through Discord. It is included in all subscription plans.
