Add image optimization to WebP format by mrbiggred · Pull Request #113 · weeklydevchat/weeklydevchat.github.io

mrbiggred · 2026-04-24T16:33:03Z

Created a script (scripts/optimize_all_images.sh) to optimize all the images and ran it on the site. The script uses the scripts/optimize_image.py to convert the image to a wepb format.

The summary of the compression is:

Summary: 91 converted, 0 skipped, 0 failed
Total size: 58.02 MB → 7.28 MB (-87.4%)
Saved: 50.74 MB
