What IOPaint is
IOPaint is a free, open-source image repair and fill tool built on advanced AI models. It can erase unwanted objects, inpaint new content into a selected area, outpaint beyond the edges to enlarge an image, replace objects with something else, and even generate text inside a picture. There is also a Paint By Example mode where you show the tool a sample and it draws something similar. Because the project is fully self-hosted, everything runs on your own machine, which keeps your images private. The team also ships OptiClean, a native macOS app for quick removal work.
What you can do with it
- Erase unwanted objects, watermarks, or blemishes
- Inpaint new content into a selected region
- Outpaint to extend an image beyond its borders
- Replace an object with an AI-generated one
- Generate text inside an image
Who it is for
- Users who need a free object removal tool
- Anyone who wants private, local image editing
- Creators who need to extend or rebuild images
What to watch out for
Self-hosting means you need to install and configure the software yourself, and the AI model files can be large, so plan for disk space and some setup time. Output quality changes depending on which model you choose and how complex the edit is, so results are not always perfect on the first try. As an open-source project, features and model support can change between releases. If you prefer a simple hosted web editor, this tool may feel more technical than commercial alternatives, but it gives you full control and privacy in return. Free tiers and usage limits can change, so check the current rules on the official page before relying on it long term.
