Site Performance Testers

Hi @bgoerzen88,

Thank you for your message.

Can you give me your website URL? I will check it and get back to you with the conclusions. Make sure my plugin is active now.

Best, Mateusz

Hello,

The site is https://tableneeds.com/.

In the Hubspot report it tells me to “SPEED_UP_LARGEST_CONTENTFUL_PAINT” but doesn’t give me the actual score.

Thanks for any help!

Thank you @bgoerzen88,

I ran a test on your website. I simulated browsers with and without WebP support to make sure everything was working. Thanks to this, I can check how much your original images weigh (i.e. what was before installing our plugin) and how much the images converted by our plugin weigh.

Here are the results of my tests (I am also sending screenshots as attachments):

• original images on your homepage weigh 4.7 MB: https://i.snipboard.io/lkIaO4.jpg
• images in WebP format weigh 0.54 MB (545 kB): https://i.snipboard.io/T3kGfU.jpg

This means that the plugin is working properly and all images are displayed in the version converted by the plugin.

Below I have attached the instructions:

• a video showing how the plugin works: https://www.youtube.com/watch?v=Ls2h38avpRw
• a tutorial describing how to test the plugin: https://mattplugins.com/docs/how-to-test-converter-for-media-plugin

If you want to gain even more, you can try the AVIF format. For your site, images converted to AVIF should weigh 50% less than images converted to WebP.

You must remember that image optimization is one of the stages of website optimization. As you can see, the effects are very large and can be even greater. Nevertheless, you need to take care of your entire website to achieve the best results.

Hi Mateusz,

All of that information is really helpful! And I had no doubt the plugin was working as expected. I could see the difference in file size when doing my testing as well.

What I was referring to was more so when you ran the website through a site tester like https://www.webpagetest.org/. If the largest contentful paint is an image, it still shows it as a .png or jpg.

Hubspot tests report a high LCP as well but it doesn’t tell me what the actual LCP score was. I’m assuming it’s scanning the .png instead of .webp? Or something along those lines?

Clients get really hung up on “tests” instead of how the site actually performs and trying to “clean up” a report that shows a high LCP even though the images are compressed and small is kind of hard! lol.

But if there’s not an issue with the site scanners then I’ll use your provided information to show that the site is actually serving webp images and the scanners are wrong :).

Thank you!

@bgoerzen88 Using the webpagetest.org tool in the Request Details section, you can see that the images in the Content Type column have the value “image/webp”. Note that the plugin doesn’t change URLs, so you won’t see “.webp” in the URL.

Ah, I see that. Thank you! You’ve been more than helpful and I will be sure to recommend and use your plugin again in the future!
