How to remove an image background without uploading it

Background removal here is a foreground mask computed on your machine, then an export from that mask. The tool is https://msh.zone/image/cutout. It does not submit the photo to a cutout API.

The model download is not the photo

The first time you select a preset, the browser downloads that model's weights and keeps them in its cache. Later cutouts in the same browser use the cache. They do not send the photo to a server. Clearing site data, switching browsers, or picking a preset whose weights are not cached yet downloads the weights again. The progress indicator is the model file, not your picture.

That is the only network behavior to know before you cut out: one model download, no photo upload. Compress and convert do not even download a model. See compress without uploading.

Presets and the edge

The three presets trade speed against edge detail:

• Fast is for a product or a simple portrait on a plain background. A clean edge does not need the heavier model.
• Balanced is the start when you have no special reason to pick another.
• Quality is for hair, fur, lace, glass, and translucent edges. It is slower, and those pictures are why it exists.

Fix the mask after it appears. The keep brush restores subject that was cut off. The erase brush clears background that remained. Feathering softens a hard edge. A slight contract removes a fringe of the old background color. Then decide whether the background stays transparent, becomes a flat color, or sits on another image.

Export and batches

Use PNG or WebP for a transparent result. JPG turns transparency into an opaque fill. If the next step must be JPG, export the transparent file here and then convert it onto the background color you choose, so the fill is yours rather than a leftover fringe.

The list can hold many photos. Preset, feather, and contract can be shared. Brush strokes stay on the image you are looking at. For a batch, lock the preset on one representative photo, check the edge, then run the rest, and repair by hand only where it is needed. The general pattern for a folder is in a folder of photos.

What it will not do

An automatic mask misses on busy backgrounds, fine hair, and translucent objects. The brushes are how you correct that, not an optional extra. Cutout also does not increase resolution or retouch a portrait. It answers one question: how to separate the subject from the background, on this device.
