IOPaint is a free, open-source and fully self-hostable inpainting/outpainting tool powered by state-of-the-art AI models. You can employ a variety of models within IOPaint to alter images, encompassing modifications such as:

Erase: Remove any unwanted object, defect, watermarks, people. I have also developed a macOS native app called OptiClean (opens in a new tab) that provides this feature. Inpainting: Make modifications to specific parts of the image, add new objects, or replace anything on your pictures. Outpainting: Generate new pixels around your images to make it larger.
