Comment afficher des images au format WebP dans WordPress

1. The problem with the suggested HTML implementation is that Chrome will make two requests, one for WEBP and another one for JPEG resulting in double requests and increasing the page load time.

   Répondre

   • Hey dear,

     It doesn’t create two requests(as you are saying) instead it automatically serve only one type image format either WebP or JPEG according to HTTP accept type.

     I’d suggest please try one more time and look carefully at Network Timeline in the browser console. If you see there are double requests, please email me your HTML code and timeline screenshot also. I’d love to review it. I believe it should work fine for you too.

     Thanks & Regards,

     • I installed the code into the functions.php. And as you said it did allow me to upload in my WP theme. The problem is that the image doesn’t allow cropping so it won’t allow me to use it on the site.

2. I haven’t added anything except the last code from your post in function.php to support Webp format on all of future media uploads. Do I need to add any thing else ? or will it create any kind of issue for users whose browsers are yet unsupported to this format?
   anyway keep up the good work 😉

   • That’s all. Now you can easily upload webp directly in your WordPress Dashboard. No extra things to do. Just feel free to use it with picture HTML tag. So, it will support for all browsers, without any issues. Thanks

3. Hi Gulshan,

   Even after putting the code snippet in the function.php file.

   I still have the same error message when I try to upload webp format. The message is « sorry this file type is not permitted for security reasons ».

   Can you help fix this?

   Thanks.

10. It works great in Chrome and Firefox on the PC/Laptop. BUT, the webp images are not displayed on iPhone (Chrome and Safari)

    Répondre

    • Safari is not supporting webP. Chrome on iOS is based on Safari, too. So webP won‘t work on iOS at all and you have to serve a fallback image.

      Répondre

11. Why is not wordpress supporting WEBP format by default?Its high time now.

    Répondre

12. I have tried this method to enable WebP format images on my site, but I am encountering some unknown error. My site showing a low score on google page speed insight.

    Répondre

    • May I know please which specific method you have tried? Also, please share the screenshot of error. I will try my best to help you.

17. Hi Gulshan. Any free plugin(totally free) for converting jpg to webp format. God Bless you.

    Répondre

    • First option which is WebP Express.

      Répondre

      • Thank You! Gulshan

        Répondre

18. Hi, this is a good article, but
    It is better to install the plugin or put the code directly for webp
    This way, each image does not create two urls. Does it cause a problem in the SEO site?

    Répondre

    • Dynamic rewriting from Server side doesn’t create two URLs instead it servers same just by changing response as per browser support.

      Répondre

    • A plugin is recommended way.

19. I have a question about ShortPixel method.

    I use Plesk panel with NGINX
    There is a section called Additional nginx directives
    Here you can specify the settings for the nginx reverse proxy server that runs in front of Apache. Your directives will override the server-wide nginx configuration. For example, you may want to change the connection timeout or to pack requests with gzip. Use the same syntax as you use for nginx.conf. For example, if you want to pack all the proxied requests with gzip, add the line: ‘gzip_proxied any;’.

    can i add codes there i dont know?

    map $http_accept $webp_suffix {
    default «  »;
    « ~*webp » « .webp »;
    }

    location ~* ^(/wp-content/.+).(png|jpe?g)$ {
    set $base $1;
    set $webp_uri $base$webp_suffix;
    set $webp_old_uri $base.$2$webp_suffix;
    set $root « <> »;
    root $root;
    add_header Vary Accept;
    if ( !-f $root$webp_uri ) {
    add_header X_WebP_SP_Miss $root$webp_uri;
    }
    try_files $webp_uri $webp_old_uri $uri =404;

    You used these sentences!
    before the server directive and inside directive.
    I read your Installing WordPress at NGINX topic so
    If i try to add these from codes is this right?

    map $http_accept $webp_suffix {
    default «  »;

20. Comment supprimer le lien hypertexte pour le format d’image webp ?

    Répondre

    • Je suppose que vous voulez supprimer l’extension .webp de l’URL. Vous devez essayer l’approche de réécriture.

21. Le format WebP a-t-il déjà posé des problèmes de référencement ? Est-il préférable de l’utiliser en jpg ou de cette manière ?

    Répondre

    • Google recommande officiellement d’utiliser des images au format WebP et JPG comme solution de rechange.
