SimpleJPEGQuality is a plugin that adds a JPEG quality setting to the WordPress media settings page, which is used to determine the image quality of thumbnails, post images, headers, and other images which have been uploaded and then resized by WordPress. It will have no effect on the quality of the original uploaded images, or that of any images that were resized before this plugin was installed.
This plugin will also affect the quality level of JPEGs resized by plugins that use the image functions of WordPress (such as Auto Post Thumbnail). Image plugins that use their own code (such as Lazyest Gallery, Ungallery, and Post Thumbnail Editor) will not be affected.
The plugin has no extra requirements and has been tested with the twentyten through twentyfourteen themes.
Development on this plugin has halted. Other developers should feel free to use the Apache-licensed code for their own projects.

URBAN BASE

In WordPress 6.1, a WebP version is generated by default when an image is uploaded and displayed in the frontend.
The WebP format generally compresses the images well.
But in certain cases the WebP version can be larger than the original image.
If WebP causes problems on your website, you can disable this function here.

Disable WebP

A small plugin to disable the new WebP standard in the settings.
