Disable Thumbnail Generation
Prevents WordPress from automatically creating multiple image sizes when you upload images. Saves disk space and speeds up uploads. Existing images keep their thumbnails, but new uploads only keep the original.
Overview
Controls which intermediate image sizes WordPress generates for new uploads. Disable every thumbnail size, or pick specific registered sizes to skip. Existing images keep their current thumbnails; pair with Regenerate Thumbnails only when you intentionally want to rebuild. Ideal when a CDN or external image service handles resizing.
Who is this for?
- Sites using a CDN or image CDN that resizes on the fly
- Teams tired of disk bloat from unused WordPress image sizes
- Developers who only need a few registered sizes and want the rest off
Features

Selective size disable

Works with registered sizes
