By default, WordPress generates multiple image sizes every time you upload an image, which can significantly slow down your site’s loading speed. These different image sizes are created to display images in various sizes across your website.
Generating multiple image sizes can significantly slow down your site’s loading speed as it takes more disk space and server resources. So disabling generating image sizes can help you save valuable resources.
However, there is no option within WordPress to disable image sizes. If you are using the Nexter Extension (Free) plugin, you can easily disable generating image sizes on your WordPress website.
How to Disable Image Sizes with the Nexter Extension?
To disable image sizes with the Nexter theme, from the WordPress Dashboard, go to Appearance > Nexter Settings > Performance.
Then go to the Disable Image Sizes section and click the Settings button.
It will open the Disable Image Sizes popup, here you’ll see all the different image sizes your site is generating.
You can individually disable all the image sizes.
Turn on the toggle for the image sizes you want to disable, then click on the Save button.
