AI Image Inpainting

Despite the name, it does not use machine learning. It runs diffusion inpainting, a classic image-processing method. The painted area is filled from its edge inward: each missing pixel takes a distance-weighted average of the known pixels around it, layer by layer, until the hole is closed. Then repeated neighbor averaging smooths the fill so it blends into the surroundings without visible seams. The result continues the colors and tones that border the area you painted.

Click the file area and choose an image. The photo appears with a note asking you to paint over what you want to remove. Drag across the object with a mouse, finger or pen, and your strokes show as translucent red. Click Clear Mask to start the painting again. When the object is covered, click Perform Inpainting. The area is filled, the photo updates on the page and a PNG downloads, named with -inpainted after your file name.

It does best with small objects on smooth or even backgrounds: dust spots and sensor specks, thin wires and power lines against the sky, skin blemishes, stray hairs on a studio backdrop, and small signs or marks on plain walls. Because it blends the colors at the edges of the hole, it cannot invent detailed texture. Large areas, or objects in front of grass, brick, foliage, faces or patterned fabric, come out as a smooth, soft patch, so use a clone or healing tool in your editor for those.

Cover the whole object, including its soft edge or shadow, with a small margin of background around it, so no fringe is left behind. Do not paint more than you need, because the larger the hole, the softer the fill. Several small passes work better than one big one: paint one object, click Perform Inpainting, check the result, then paint the next. The brush is a fixed size of about 30 pixels on screen, so thin lines need only one stroke.

Only the pixels you paint are changed; everything outside the mask stays exactly as it was. Each time you click Perform Inpainting, the tool saves the whole photo as a lossless PNG at its original pixel dimensions. You can open JPG, PNG, WebP or any other image your browser can display. PNG files from large camera images are big, so convert the result to JPEG afterward if you need a lighter file, and keep your original as a backup.

Yes. It is free, adds no watermark and needs no software installation. The painting and filling happen in your browser on your own device, so your photo never leaves it. The first time, you answer that you're a photographer and create or log into a free Imagen account, and from then on this tool and every other one on the site is unlocked for you.
