GUIDE

How to clean up a marked part of an image locally

This tool is for small, manual cleanups on simple backgrounds. It runs in your browser, so you can work without creating an account or sending the selected image to this website.

Use the tool in four steps

1. Choose an image. Select a JPG, PNG, or WebP file. The current limits are 8 MiB per file and a longest side of 4096 pixels.

2. Mark the area. Paint over only the text, label, or small visual mark you want to clean. Keep the painted area slightly larger than the mark, but avoid covering nearby details you want to preserve.

3. Repair and review. The tool samples pixels outside the painted area to create a local fill. Review the result before downloading; use Clear marks and try a tighter selection if necessary.

4. Download PNG. The exported filename is local-watermark-cleanup.png.

When it works best

Local repair works best when the marked area sits on a simple surface, such as a sky, wall, paper background, or a broad area with similar colour. It can remove the visible mark, but the repaired patch may look smoother than the surrounding texture.

What it does not do

This is not an automatic AI watermark detector. It does not identify marks for you, reconstruct complex objects behind a mark, or guarantee a natural result on detailed patterns, faces, text, or dense textures.

Privacy note
