JGWS Media Optimizer

Turn your JPG and JPEG images into WebP automatically — directly during upload to the WordPress Media Library.

JGWS Media Optimizer is a lightweight WordPress plugin that handles WebP conversion automatically during Media Library uploads, without requiring an external image optimization service.

Upload a JPG or JPEG and let the plugin handle the conversion automatically.

The FREE version also adds a clear WEBP label to converted images in the Media Library, so you can instantly see which files have been converted.

You can optionally preserve the original JPG/JPEG file as a separate Media Library attachment, giving you access to both the original file and the generated WebP version.

WebP can provide smaller image files while maintaining good image quality, which can help reduce storage usage and improve page loading performance.

The plugin uses WordPress native image processing mechanisms and does not require an external image optimization service.

How It Works

When a JPG or JPEG image is uploaded to the WordPress Media Library, JGWS Media Optimizer uses the WordPress image editor system to process the image and its registered sizes.

The uploaded JPG/JPEG image and its generated image sizes are converted to WebP.

The FREE version uses a fixed WebP quality of 85.

WebP files are clearly marked with a WEBP label in the Media Library.

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.
