ABOUT THIS TOOL
Why use this tool?
WebP images are typically 30% to 70% smaller than legacy JPEGs and PNGs while retaining crisp visual fidelity. Faster loading images directly decrease bounce rates on mobile connections.
Frequently Asked Questions
Are my private photos uploaded to your server during conversion?
No! The conversion runs 100% locally on your machine using your browser’s HTML5 Canvas engine. Not a single pixel is ever uploaded to any cloud server.
Do all modern web browsers support the WebP image format?
Yes. WebP is supported natively by Google Chrome, Apple Safari (iOS & macOS), Mozilla Firefox, Microsoft Edge, and Opera (97%+ global browser coverage).
How much file size reduction can I expect?
Most unoptimized camera photos and banner graphics see between 40% and 80% file size reduction with virtually no noticeable loss in visual clarity.
