The Google PageSpeed Insights Tool suggests using next-gen images. This article will explain how to use next-gen images on a Blogger blog.
Blogger offers a strong image server from Google that can handle nearly all types of images based on your needs.
Blogger will automatically change these images into WebP format. Now, let’s see how to ask for the next-gen image from Blogger: just upload an image file to the Blogger dashboard, as illustrated below.
Then, choose HTML mode to change the Blogger image to the webP NextGen format.
You will observe code like the one displayed above. It’s necessary to modify the source link for the image found in the tag.
Using the Google image server, you can provide various image sizes and formats.
To upload the next webp images to Blogger, use the -rw value shown in the image. Just change s320 to s320-rw, or s640 to s640-rw. Make sure to place -rw immediately after the image size for webP.
Blogger changed the way image URLs are organized in 2025.
The previous format for images is no longer in use, but older uploads remain unchanged.
The new URL format includes important details about images, such as their size and type.
Is your theme unable to support webP format?
Every image you convert will be rendered as a webP image. However, can your Blogger theme handle requests for webP images?
This could lead to issues with your theme, such as some gadgets not appearing.
with
('/s72-c','/s680-rw').replace('/s72-rc','/s680-rw')
You should use this to all related codes found in the principal function file. You have to decode the theme file if you're using free Blogger themes.
Not certain about how to accomplish that? For your blog, you can use our WebP image friendly Blogger theme. In webP format, this topic will show all the widget pictures. Follow the rw technique for every picture you upload, however, for the photos inside your posts.
