Shrinkwell Image Optimizer
Optimize images locally, find possibly unused media, and reduce WordPress backup size safely. Shrinkwell helps you compress images, generate WebP/AVIF, and review possibly unused media before it bloats your backups. Images are processed on your own server, with no external compression API and no account required. Run a safe 5-image test first, review the results, then optimize your media library with more confidence. Built for agencies, freelancers and site owners Shrinkwell is designed for WordPress maintenance, handoff and cleanup work where you need to show what was optimized, what was skipped, and which media may need review.

Modern Image Formats
This plugin adds WebP and AVIF support for media uploads within the WordPress application. By default, AVIF images will be generated if supported on the hosting server, otherwise WebP will be used as the output format. When both formats are available, the output format can be selected under Settings > Media. Modern images will be generated only for new uploads, pre-existing images will only converted to a modern format if images are regenerated. Images can be regenerated with a plugin like Regenerate Thumbnails or via WP-CLI with the wp media regenerate command. By default, only modern image format sub-sizes will be generated for JPEG or PNG uploads – only the original uploaded file will still exist as a JPEG/PNG image, generated image sizes will be WebP or AVIF files. To change this behavior, there is a checkbox in Settings > Media “Output fallback images” that – when checked – will result in the plugin generating both the original format as well as WebP or AVIF images for every sub-size (noting again that this will only affect newly uploaded images, i.e. after making said change). This plugin was formerly known as WebP Uploads.
