Overview

RMBG is a background removal tool that lets you upload an image via a drag-and-drop web UI and download the result as a transparent PNG. It uses the rembg library powered by U2-Net for high-quality background removal.

Features

  • Web UI -- drag-and-drop image upload with instant background removal and automatic download
  • CLI -- process single images from the command line
  • Dockerized -- single docker build && docker run to get it running anywhere
  • Cloud Run deployment -- live on Google Cloud Run for serverless, on-demand processing

How It Works

  1. Upload an image through the browser (or pass it via CLI)
  2. The Flask server passes it through the U2-Net ONNX model via rembg
  3. Background is removed and the result is returned as a transparent PNG
