Images in avif

In order to make copies of images in a modern format to serve alongside with usual ones:

find ./static/images -type f -name '*.png' -exec sh -c 'avifenc --min 10 --max 30 $1 "${1%.png}.avif"' _ {} \;

Easier alternative than harden-than-I-thought task of getting avifenc working is converting images to avif using https://avif.io/.

Reduce PNG and JPG image size before publishing

It's easy to reduce the images size without altering their content:

find . -type f -iname "*.png" -exec optipng -o7 -preserve {} \;
find . -type f -iname "*.png" -exec advpng -z4 {} \;
find . -type f \( -iname "*.jpg" -o -iname "*.jpeg" \) -exec jpegoptim --strip-none {} \;
