A simple Python script that converts a batch of images of various formats into WebP format.

Current list of image formats:

• .png
• .jpg

Note: I recommend virtual environments (venv) unless you know what you're doing of course

See the folks here for a very good primer on venvs and how to create your own: RealPython - Python Virtual Environments: A Primer

First, clone this repo (or download the file itself: main.py)

Afterwards, install the necessary library (Pillow for image manipulation) with your package manager (ie. pip).

$ pip install -r requirements.txt

This relies on reading all images within an input folder within the same directory as the script.

If you do not have an input folder, the script will throw an exception to remind you to create an input folder.

Place all images that requires converting into the input folder. Your working directory should look something like this:

py-image-to-webp/
├── input/
  ├── image1.png
  ├── image2.png
  ├── ...
  ├── imageX.jpg
├── requirements.txt
├── main.py         <--- main script!
├── ...

Once you have loaded the input folder with your images, run the script. I use wsl to run my python script so your method / operating system will vary:

$ python3 main.py
$
$ Converting image1.jpg
$ Converting image2.jpg
$ ...
$ Converting imageX.png

The script will generator an output folder within the same directory as the script so you should see that folder. Within the output folder, you should see your batch of .webp files and that should be it!
