Did the job with a minimum of effort
Although I am using a Cloudflare Worker with Cloudlare Transformations for image delivery, Google Pagespeed was still complaining about using unoptimised formats on my home page featured image. A quick run of this plugin completely solved the issue with a minimum of fuss.
The only webp / avif plugin you’ll ever need
I registered so I can write the review, the plugin works absolutely flawlessly. If you are trying to decide between all the plugins for webp / avif support you can stop, I did it for you and this is the one you need.
Much love, thanks for your work <3
Very useful and practical
Easy to use and verify, images are actually getting converted to webp which is a good sight, thank you for this wonderful plugin
Great and simply
Simple to use, no difficulty in settings, does its job well. Compresses images to webp and avif, and also creates the whole series of thumbnails.
Remarkable work
This plugin does the job it advertises and does it well. The site’s pages use reduced images and it’s very effective. The reduction work takes time if you have a large stock but then it’s done as you go along.
Well done to the developers
Give A Try!
