rembg is a popular Python package for automatically removing the background from images using deep learning. It’s fast, easy to use, and runs entirely on your local machine.
Automatic Background Removal
rembg detects the subject of an image and removes the background, making it fully transparent (outputs a PNG with alpha channel).
No Cloud Uploads—Runs Locally All processing happens on your computer. No need to upload images to an external server.
Versatile Works with people, products, animals, objects—almost any image with a clear foreground.
Fast Uses pre-trained ONNX models for efficient, reliable performance (CPU or GPU).
Scriptable and Programmable Use from the command line or directly in your Python scripts.
