About the WebP format
A quick primer on what WebP is and how this tool works.
What is WebP?
WebP is a modern image format developed by Google. At equivalent visual quality, it typically produces smaller files than JPG or PNG, especially for photos and complex graphics.
Why it helps performance
Smaller image files mean faster page loads, better Core Web Vitals scores (particularly Largest Contentful Paint), and less bandwidth for visitors on mobile connections.
Everything happens locally
This tool decodes and re-encodes your images entirely in your browser using the Canvas API. Your files are never uploaded, so they never leave your device.
When to keep JPG or PNG
Keep the original format when you need maximum compatibility with older software, lossless editing later, or print production. For most websites, WebP is a safe, effective upgrade.
