First image loads the AI model (~15 MB) — cached after that.

How it works

ConvertCabin runs a small open-source segmentation model (U²-Net) with onnxruntime-web inside this browser tab. It predicts which pixels are the subject, turns the rest transparent, and hands the cutout straight back to you. Nothing is uploaded.

The first image downloads the model and runtime (about 15 MB), which your browser caches, so later images are quicker and even work offline.

Keeping or replacing the background

Once the subject is cut out you have three choices, and switching between them is instant because it doesn't re-run the model: Transparent exports a PNG with a see-through background, Colour fills a solid backdrop, and Image places your own photo behind the subject. It's an automatic, lightweight model, so fine edges like hair won't be pixel-perfect — clear subjects on a contrasting background work best.

Frequently asked questions

How do I remove an image background?
Drop an image and wait for the model to load on the first run. The subject is cut out automatically; then keep the background transparent, fill a colour, or replace it with your own image, and download.
Can I replace the background, not just delete it?
Yes. After the cutout, choose Colour to fill a solid background, or Image to drop in your own photo behind the subject. Switching is instant and doesn't re-run the model.
Is my image uploaded?
No. It runs entirely on your device using a local AI model; your image is never sent to a server.
Why aren't the edges perfect?
This uses a lightweight automatic model, so fine details like hair or thin objects can be imperfect. Clear subjects on a contrasting background give the best results.
