Perfect for profile picture processing for your website or batch work for ID cards, autocrop will output images centered around the biggest face detected.
From the command line:
usage: [-h] [-o OUTPUT] [-i INPUT] [-w WIDTH] [-H HEIGHT] [-v]
Automatically crops faces from batches of pictures
optional arguments:
-h, --help
Show this help message and exit
-o, --output, -p, --path
Folder where cropped images will be placed.
Default: current working directory
-r, --reject
Folder where images without detected faces will be placed.
Default: same as output directory
-i, --input
Folder where images to crop are located.
Default: current working directory
-w, --width
Width of cropped files in px. Default=500
-H, --height
Height of cropped files in px. Default=500
--facePercent
Percentage of Face height to image height (zoom factor)
--padUp
Padding up value compared to padDown. Default=50
--padDown
Padding down value compared to padDown. Default=50
--padLeft
Padding left value compared to padRight. Default=50
--padRight
Padding right value compared to padLeft. Default=50
-v, --version
Show program's version number and exit
- Crop every image in the
pics
folder, resize them to 400 px squares, and output them in thecrop
directory:autocrop -i pics -o crop -w 400 -H 400
.- Images where a face can't be detected will be left in
crop
.
- Same as above, but output the images with undetected faces to the
reject
folder:autocrop -i pics -o crop -r nofaces -w 400 -H 400
.
- Same as the first example, but add more padding at the bottom:
autocrop -i pics -o crop -w 400 -H 400 --facePercent 50 --padUp 20 --padDown 50
.
If no output folder is added, asks for confirmation and destructively crops images in-place.

Simple! In your command line, type:
pip install autocrop
Autocrop uses OpenCV to perform face detection, which is installed through binary wheels. If you already have OpenCV 3+ installed, you may wish to uninstall the additional OpenCV installation: pip uninstall opencv-python
.
In some cases, you may wish the package directly, instead of through PyPI:
cd ~
git clone https://github.com/leblancfg/autocrop
cd autocrop
pip install .
Development of a conda-forge
package for the Anaconda Python distribution is also currently slated for development. Please leave feedback on issue #7 if you are insterested in helping out.
Best practice for your projects is of course to use virtual environments. At the very least, you will need to have pip installed.
Autocrop is currently being tested on:
- Python:
- 2.7
- 3.4
- 3.5
- 3.6
- OS:
- Linux
- macOS
- Windows

Although autocrop is essentially a CLI wrapper around a single OpenCV function, it is actively developed. It has active users throughout the world.
