Installing and Using the Python Rembg Library for Image Background Removal

The Rembg library for Python can automatically remove backgrounds from images using AI models, as demonstrated by the example image shown at the beginning of the article.

Installation

For the CPU version, run:

pip install rembg

For the GPU‑accelerated version, run:

pip install rembg[gpu]

Quick start

Command‑line usage

To process a single image:

rembg i path/to/input.png path/to/output.png

To process multiple images in a folder (batch mode):

rembg p path/to/input path/to/output

Using Rembg in Python

Read the image as binary data, call remove , and write the result:

from rembg import remove # Path of the image to process input_path = 'input.png' # Path where the result will be saved output_path = 'output.png' with open(input_path, 'rb') as i: with open(output_path, 'wb') as o: input_data = i.read() output_data = remove(input_data) o.write(output_data)
