How to convert PNG to WebP
Upload one or more PNG files, choose a quality level, and download the WebP results. Everything runs locally, so your images stay private.
WebP is a modern image format that compresses better than both PNG and JPG while still supporting transparency. Switching site images to WebP is one of the easiest ways to speed up load times.
Frequently asked questions
Why convert PNG to WebP?
WebP typically produces significantly smaller files than PNG at similar quality, while still supporting transparency. Smaller images mean faster page loads and better Core Web Vitals scores.
Does WebP keep transparency?
Yes. Unlike JPG, WebP supports an alpha channel, so transparent areas in your PNG are preserved.
Do all browsers support WebP?
All modern browsers (Chrome, Firefox, Edge, Safari) support WebP. For very old browsers you may want to keep a PNG or JPG fallback.
Are my images uploaded anywhere?
No. Conversion happens locally in your browser using the HTML canvas — your files never leave your device.
