Background Remover Batch

Python utility for removing image backgrounds in bulk from a single file or an entire folder and exporting transparent PNGs.

Features

• processes one file or a whole directory
• keeps filenames predictable
• writes transparent PNG outputs
• supports nested folders when scanning a directory
• works well for product mockups, icon assets, and quick cutout batches

Requirements

• Python 3.10+
• rembg
• Pillow

Install

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

Usage

Process a folder called input/ and write results into output/:

python remove_background.py input --output output

Process a single file:

python remove_background.py ./input/example.jpg --output ./output

Use a specific rembg model:

python remove_background.py ./input --output ./output --model u2net

Notes

• The repository ignores local input/, output/, and venv/ folders so sample images and generated assets do not bloat Git history.
• Outputs are always saved as PNG so the alpha channel is preserved.
