The plugin uses WordPress image processing mechanisms instead of replacing the standard Media Library workflow. WebP images can reduce file size while maintaining good image quality, which can help reduce storage usage and improve page loading performance. The FREE version is designed to work automatically after installation, without requiring an external image optimization service. ### Features * Automatic conversion of newly uploaded JPG and JPEG images to WebP. * WordPress-generated image sizes are also created in WebP format. * Default WebP quality of 85. * Optional preservation of the original JPG/JPEG file. * Preserved original JPG/JPEG files are added as separate attachments to the Media Library. * Preserved original JPG/JPEG files remain available independently from the WebP attachment. * PDF preview images generated by WordPress are not converted to WebP. * Uses WordPress native image processing APIs. * No external image optimization service is required. ### FREE and PRO The FREE version provides automatic JPG/JPEG to WebP conversion with a fixed WebP quality of 85. JGWS Media Optimizer PRO extends the FREE version with additional formats, greater control over the conversion process, and additional Media Library features. The PRO version includes: * Configurable WebP and AVIF quality from 1 to 100. * PNG to WebP and AVIF conversion. * Separate conversion settings for JPG/JPEG and PNG. * Lossless PNG to WebP conversion. * Optional preservation of original PNG files. * Clear file format labels in the Media Library, making it easier to identify formats and work with media files.

The uploaded JPG/JPEG image and its generated image sizes are converted to WebP through the WordPress image editor system. The FREE version uses a fixed WebP quality of 85. By default, the original JPG/JPEG file is removed after a successful conversion. If the option to preserve the original file is enabled, the JPG/JPEG file is kept as a separate attachment in the Media Library. ### Settings The FREE version provides the following setting: * Keep original JPG/JPEG files – keeps the original JPG/JPEG file as a separate Media Library attachment. WebP quality is fixed at 85 in the FREE version. ### External Services This plugin uses Freemius, a third-party service, to provide plugin account, licensing, premium version, and update-related functionality.
