WebPio: WebP Converter and Image Optimizer for WordPress9.3.3
Overview
WebPio is a WordPress plugin that converts JPEG and PNG images to WebP format without visible quality loss. WebP files are typically about half the size of the originals, so pages load faster, Core Web Vitals improve and hosting bandwidth drops — with unlimited conversions included.
Key Features
Unlimited bulk conversion
Convert your entire media library to WebP in bulk, with no conversion cap.
Automatic conversion on upload
New JPEG and PNG uploads are converted to WebP automatically going forward.
Quality control slider
Set the compression level yourself so you can balance file size against visual quality.
Original-file fallback
Keeps the original image and serves it automatically to any browser that can't display WebP.
Works with WooCommerce product images
Converts product galleries and thumbnails the same way it handles the rest of your media library.
Frequently Asked Questions
Does converting to WebP reduce image quality?
You control the compression level with the quality slider, so you can keep quality visually identical to the original while still cutting file size.
What happens in browsers that don't support WebP?
WebPio keeps the original JPEG or PNG file and serves it automatically as a fallback, so nothing ever breaks for visitors on older browsers.
Can I bulk convert my existing media library?
Yes — bulk conversion runs across your entire existing media library, not just new uploads.
