webp_check
A Python script to check if images on a website have a Webp equivalent. If none is found, the script will create one in the same directory as the discovered jpeg/jpg/png with the same filename.
This script is ideally configured to be run on a cron.
In order to actually serve the WebP images to users, you configure a webworker to handle requests. If your site is on Cloudflare, worker.js can be copied and pasted directly into a new Cloudflare worker.
If not, modify the code as needed to work with your application.
