down-webp

Batch download images from url and convert to webp. Don't use services like TinyPNG, CloudConvert or Convertio with accounts and payments -> do it on your machine!

Caution! Does not download and compress CSS background images (yet)

Also performs compression by default.

Install

pip install -r requirements.txt

It's recommended to use venv

Execute

See full parameter documentation like this:

python3 down-webp.py

Saves the images in the folder (url)-images-75-down (default quality level is 75)

python3 down-webp.py --url URL

The quality can be specified as an additional parameter (1-95), then it will be saved in a different folder. Example:

python3 down-webp.py --url URL --quality 50
# saves downloaded images in (url)-images-50-down
# saves compressed images in (url)-images-50-compressed

The images can have a prefix (order of the image) if you need this. In that case, call the script as follows:

python3 down-webp.py --url URL --add_prefix True

If the files should not be converted to webp, also add this parameter:

--no_webp True

Single file mode

Use this to convert and compress a local file

python3 down-webp.py --file FILENAME
