Only a few images are served as webp

Hi @rom174,

Thank you for your message.

1. Can you provide a link to your site? It doesn’t matter how often you load files. Their exchange is managed by the server using the rules saved in the .htaccess file.

2. This is about CDN, when you store image files on another server. Then we don’t have access to it and we can’t do anything. Probably all your site is on CDN, right? Then it will work.

Hello @mateuszgbiorczyk

Thank you very much for your reply !

Where can I contact you to send you the link ?

1/ Just to be sure, what I meant is at each loading/reloading page, I only have 1, 2 or 3 webp images over 23 (for instance) images. All the others are served as jpg, jpeg or png while their webp version well exists. So, what I don’t understand is that the rules are exactly the same for each images but only 1, 2 or 3 of them seems to be affected in each pages.

2/ Yes all the site should be on a CDN, I was trying to check it but it is kindly hard because I don’t manage CDN propagation, it is manage by the hoster. I tried to CURL a random file and I saw it is hosted in Canada, so if the first random file is there, I guess it is ok for the whole site.

On my profile at www.ads-software.com you will find a link to my website. And there is an e-mail address.

1. Do you use something to compress your images? Remember that if the converted photo is larger than the original one, the original one will be used.

Yes I have used a software to compress it.
It decreased the size from 1400mo to 400mo, so I can say almost for sure every pictures have been optimized.
I have send you an email.

Thanks again

I checked it out. On the main page you have 4 photos uploaded from the /wp-content/uploads/ directory. They are loaded in WebP format, although it also happened to me that they showed up as JPEG (only once).

However, this looks like some server error. Some built-in cache – it’s hard to say. Please contact your server administrator.

Hello @mateuszgbiorczyk

Well, very interesting that you say it because for me that was the fact there is an “implicite” rewritted URL due to the rewrite rule in htaccess. This is how I was thinking it works, let me know where I am wrong : when the original url is requested, the server first checks if the equivalent webp format exists if it exists, it serves the webp image BUT WITHOUT adding a ressource line to the waterfall, so the original URL of the original image is displayed.
From my side, I always see images coming from /wp-content/uploads/ with .jpg/.png extensions but the type let me know if it is webp or jpg. The weird thing is that 2.5 days later, there are still jpg/png type instead only webp type in the images served by CDN.

However, this looks like some server error. Some built-in cache – it’s hard to say. Please contact your server administrator.

Do you mean the fact the images come from the /wp-content/uploads/ directory instead of /wp-content/uploads-webpc/ directory is a server error ?
Should I really see the images coming from /wp-content/uploads-webpc/ ?

URLs are rewritten implicitly. The only thing you see in Dev Tools is Content-Type – it’s changed to image/webp. That’s the whole “magic” of this plugin, that the URLs remain unchanged and you don’t have any 301 redirects.

You should see images loaded from the /wp-content/uploads/ directory, but they will actually be implicitly loaded from /wp-content/uploads-webpc/. Content-Type will differ.

We agree.
Thank you for the support
