Selective webp conversion

Hello @sooskriszta,

Our Speed Optimizer plugin will create WebP copies of all images on your website which have been uploaded through its Media Library, with the only exception being PNG format images that are over 1MB in size.

Images in JPG, and other not PNG format, which aren’t being generated in WebP format would indicate that they haven’t been uploaded through the website’s Media Libarary, which are usually images carried over with plugins and themes.

With this in mind, please check the source path of the affected images of the website though the Development console of your browser, while previewing the website as a visitor. Images that are not in the website’s uploads/ folders, but are instead in plugins/ and/or wp-themes/ would be the aforementioned carried over images that our Speed Optimizer plugin would not generate as WebP.

If you’re experiencing this issue on a site hosted on a SiteGround server, please submit a ticket in our Help Desk, as this would provide us with a direct hands-on approach to investigate this further.

Best Regards,

Ivaylo Stoyanov

Hello @sooskriszta,

I have located your most recent conversation with our support team from your Client Area with us, and I can see that in it you are referring to the images seen in the screenshot below, which you have provided to our support team.

These images have had WebP versions of them correctly generated by our Speed Optimizer, and they are being served in WebP as expected:

All JPG images on your website’s homepage are being correctly served in WebP format:

And so are the images on the product pages on your website, such as the ones in the screenshot below.

I would like to provide you with more information on our Speed Optimizer plugin and its WebP option, so that any confusion regarding this it can be avoided.

The WebP option of our plugin creates copies of the images on your website in WebP format. The original images are left intact and remain present on your website and its configuration. When your website is visited by a browser that supports WebP, our system detects this and serves the WebP versions. Your website’s will still refer to the original images, which in this case are in JPG format, as it has been originally created with them, hence why these images are visible in the Rendered DOM of the website, as seen in your screenshot. Regardless of this, WebP images will be served instead to any browser that supports this format.

This option functions this way so that if a visitor opens your website on a browser that does not support WebP, the website simply loads the original images in their original format instead of the WebP copies. This ensures that your website remains fully operational both on modern browsers and legacy ones that do not yet support WebP.

In order for the underlying code of your website to explicitly refer to WebP images as the primary source, and so that these images are in the website’s Rendered DOM, you would either need to manually update your database entries of your website, and possibly PHP templates, or replace all images on your website with files natively in WebP format. However, our plugin’s method is preferred as it maintains maximum compatibility without destructive changes to your original media library, and ensures that your website remains fully operational on modern and legacy browsers.

I hope this clears up any uncertainties regarding this situation.

Best Regards,
