Image Compressor WebP by htmlrunner converts JPEG and PNG images in your media library to WebP format, reducing file sizes without any visible quality loss.
Your Images Never Leave Your Server
This plugin works entirely within your own hosting environment. No image data is ever transmitted to our servers or any third-party service. Every conversion runs through your server’s native PHP GD or Imagick library — the same tools already installed on virtually every hosting plan.
This means:
- Complete data privacy — your images stay on your infrastructure, period.
- No API keys or accounts — there is nothing to sign up for.
- No subscription fees — no usage limits tied to external credits.
- Works offline — no outbound connection is required for processing.
What It Does
- Converts JPEG and PNG images to WebP format directly on your server.
- Supports bulk conversion — process your entire media library in one go, or select specific images.
- Adjustable compression quality via a dedicated settings page, so you control the size-to-quality trade-off.
- Replaces original files with the WebP version to reclaim disk space.
- No configuration beyond activation is required to get started.
