Is there a way to serve webp AND jpeg with this plugin?

I use Converter for Media plugin. Their free version gives you unlimited free conversion [done on their servers even] to WebP.

I pay for their pro upgrade a ridiculously low $50/y [for so many credits I never finish even with many websites!] to get AVIF which is blazing fast compared to WebP even. And AVIF is super sharp.

These 2 plugins are the best combo I ever tested and use it with out any additional caching plugins, works best so. I just add gzip code to my .htaccess file on the server. In root of each site.

A CloudFlare Pro subscription makes it possible to cache the WebP and AVIF on CF edge and serve it from there for a further amazing speed boost if you need/ get a lot of traffic.

Note, I use Elementor Pro, which has many built in speed/performance options. Other ThemeForest themes like JupiterX also have that. Hence I need no further opt’ plugins than these 2.

And typically I never could use CF Rocket Loader (in speed settings) with any WP site but now it seems to work very well.

IMPORTANT NOTE:
When using the Converter for Media alongside this wonderful plugin you need to set in the Cache settings tab > “Overwrite the cache-control header for WordPress’s pages using web server rules” to “YES”, as the CFM plugin has it’s htaccess and if this is not set to YES then CF caches the jpeg and serves it [Public cache] instead of AVIF as private cache. Faster page load with AVIF from your server than Jpeg from CF!

When using CF Pro and or the Rocket Loader, you must in this plugin Cache tab you must set it to NO.

Hi @snipsnip,
No, this is a pure page caching plugin. If you want to do image optimization, I would personally suggest you to opt for on-the-fly image optimization services.

If you have a high traffic site, you can get Cloudflare Pro plan and use Polish feature of Cloudflare to do unlimited image optimization & servicing images in WebP format.

Alternatively, you can also use services like Optimole, Imagekit.io etc.
