This script uses pillow to convert all images in a single folder, I'll maybe add recursive support for subfolders at somepoint but I don't need it for now.
The script is able to convert multiple souce extensions to multiple extensions, it also allow you to chose casing of the export, default is snake case.
You can also provide a list of ignores names so the script don't convert those images.
In order to use the script you must setup the LOG_BASE_DIR, which will be the folder where the script will output its logging
you can disable loging in a file by commenting / deleting the FileHandler at line 20 :
log.FileHandler(f"{log_base_dir}/converter.log")
(can also rename the output file there)
converter.py [-h] [-s [SOURCE_EXTENSIONS ...]] [-t [TARGET_EXTENSIONS ...]] [-i [IGNORE_NAMES ...]] [-c CASE] [-o] path_to_exec
You can view all possibilities and options using
converter.py -h
But globally it's kinda easy to use:
python converter.py "path/to/the/folder" -s "png" "jpg" -t "webp" -o -i "mycat" -c "camel"
This will convert all .png and .jpg files in path/to/the/folder to .webp overwriting possibly existing .webp with the same name, it will export the new files in camelCase and ignore the image named "mycat" no matter its extension.
We could have used unshortcuted options as such but it's longer:
python converter.py "path/to/the/folder" --source-extensions "png" "jpg" --target-extensions "webp" --overwrite --ignore-names "mycat" --case "camel"
The script use the default logging lib from Python, it logs all levels from debug to critical, you can change the level of logging at line 16 or add new logs using log.level(message)
