Plus WebP or AVIF

It is very useful to replace the URLs of images of existing content as well.

Easy and very useful


I really like this plugin and it's very good in other aspects. However, on both of my websites, when converting in bulk, I was unable to continue the conversion for a certain period of time, indicating an Ajax 500 error. What is the reason?


500 error


This is great plugin to save my server space!



Dear developer, I prefer to donate by paypal, usdt or stripe instead of inputting my credit card elsewhere.


Great plugin
