Simple Image Sizes

This plugin lets you create custom image sizes for your site. Override your theme sizes directly on the Media settings page, regenerate thumbnails, and copy add_image_size PHP for your theme.

ℹ️ Simple Image Sizes, a Mediapapa product

Simple Image Sizes will always remain free. It is actively maintained by me (Nicolas Juen). I’m also building Mediapapa, a complementary plugin focused on understanding and organizing your media library. More on these changes

Features

• Insert images in posts at the right size using your custom sizes.
