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.

Convert HEIC images to JPEG format when upload to the Media Library.
HEIC is the file format name Apple has chosen for the “High Efficiency Image Format” (HEIF) standard. HEIF offers better compression than JPEG, so it takes up less storage space, while maintaining the same visual quality. The format has been used by default since iOS 11, i.e. for images sent through the Messages app or when exporting.
This plugin adds HEIC/HEIF support to WordPress by transparently converting the uploaded image to JPEG.
Note: ImageMagick 7.0.8-46 or above is required to be installed on the server.
