 * Hi [@akiraanastasia](https://wordpress.org/support/users/akiraanastasia/)
 * Jetpack’s Photon downloads, optimizes, and serves a cached version of each one
   of your images. However, the size of the final, optimized image still depends
   on how big the original image was; if your original image was very big, the optimized
   image will be smaller, but still too big for Google PageSpeed Insights. To solve
   that issue, we’d recommend that you optimize your images before to upload them
   to your site. No need to upload images that will be larger than 2M, for example.
   Ideally, your images shouldn’t be larger than 1M.
 * Google Pagespeed Insights or other tools like Gmetrix will often return a warning
   if it finds images that include a query string, because it thinks that means 
   that the original image is loaded and then resized in the browser. Photon images
   do include a query string (that’s the ?resize=400×400 you’ll find on most images),
   but we actually cache the resized version of the image on our CDN, so the image
   that’s served on the site is in fact optimized. No need to worry there.

 * Hello, there.
 * I do see that you have Jetpack’s Lazy Loading feature on, which is what Google
   is recommending, there. However, something must be blocking or conflicting it.
 * I see you have a few code crunching plugins (wp-rocket and wp-optimize), a couple
   image manipulating plugins, a few security plugins – there appears to be a lot
   of possible conflicts between similar plugins here, and that could cause items
   like Lazy Loading to not work properly.
 * As a first step here, I would recommend using only one plugin for optimizing 
   your code (or remove what you have now and just use Jetpack’s built-in site accelerator),
   one plugin for security, and only one plugin or feature for images (right now,
   you have Jetpack’s CDN but WP-Smush It is also trying to do the same actions).
 * Once you trim down your plugins to exclude any duplicated features, try giving
   Google another test and see if anything has improved.

 * I stopped Jetpack CDN and loaded images from server. Then this problem was gone.
   Means WP rocket resized images whenever needed. So its only conflict with Jetpack
   and other plugins?

   like to know how you detected all plugins from site?

 * Hi [@akiraanastasia](https://wordpress.org/support/users/akiraanastasia/)
 * If another plugin offers the same functionality as one of Jetpack’s features,
   a conflict is very possible and that sounds like what happened here.
 * What you can do is reactivate Jetpack and disable Lazy Images and / or the Site
   Accelerator options (specifically ‘speed up image load times’):
 * [https://jetpack.com/support/lazy-images/](https://jetpack.com/support/lazy-images/)
   
   [https://jetpack.com/support/site-accelerator/](https://jetpack.com/support/site-accelerator/)
 * If there was a conflict between Jetpack and another plugin that had any of those
   features, then either deactivating the other plugin or disabling those features
   in Jetpack should resolve the issue (and allow you to continue using Jetpack’s
   other features).
 * You also asked how we detected plugins – one of the features of Jetpack is the
   ability to manage plugins, which means the Jetpack plugin (when connected) can
   see what other plugins are active on a site. In order to troubleshoot Jetpack
   connection issues only information directly relevant to the Jetpack connection
   is available to plugin support.
 * If you are able to test the page speed with Jetpack active and disabling those
   specific features, do let us know what you find or if you have any other questions
   around this.

 * Hello there, One more question:
    What is difference between Photon CDN and SMUSH
   CDN? Both provide same service? Does jetpack can convert images to next gen webp
   format?

 * Hi [@akiraanastasia](https://wordpress.org/support/users/akiraanastasia/)
 * I took a look at [their CDN service](https://wpmudev.com/forums/topic/wp-smush-pro-how-to-activate-the-cdn-on-site/)
   and it is much similar but I can’t say anything about how their CDN exactly works
   behind.
 * I can provide you information on our CDN, and you can see how it exactly work
   here: [https://jetpack.com/support/site-accelerator/#how-site-acceleration-works](https://jetpack.com/support/site-accelerator/#how-site-acceleration-works)
 * > Does jetpack can convert images to next gen webp format?
 * If the browser supports the WebP image format, images will be automatically served
   as WebP (note that the extension won’t change).
 * In practice, that means that when you add an image block to a post with an image
   like:
    - [https://example.com/wp-content/uploads/2021/01/image-file.png](https://example.com/wp-content/uploads/2021/01/image-file.png)
 * Jetpack’s CDN will serve a matching image from its CDN instead, like so:
    - [https://i2.wp.com/example.com/wp-content/uploads/2021/01/image-file.png?resize=768%2C769&quality=100&ssl=1](https://i2.wp.com/example.com/wp-content/uploads/2021/01/image-file.png?resize=768%2C769&quality=100&ssl=1)
 * As you can see, WebP is not on the file extension list. That doesn’t mean that
   Jetpack’s CDN doesn’t support the WebP format; it just does things a bit differently.
   Jetpack doesn’t actually require that you upload and store WebP images on your
   server. Instead, it detects when a site visitor browses your site using a browser
   that supports WebP (like Chrome) and serves them images that have been optimized
   to use the WebP format.
 * More info can be found here: [https://jetpack.com/support/site-accelerator](https://jetpack.com/support/site-accelerator)
 * I hope that helps! 🙂
