Convert PNG to WebP Online Free
WebP usually saves 25–35% over PNG at the same visual quality, which is why it's the format of choice for fast-loading websites. This page opens the converter already set to WebP output — drop in your PNG (or a batch of them) and download smaller files in seconds.
WebP keeps PNG's transparency, so logos and UI assets convert cleanly. Every image is converted in your browser, so nothing is ever uploaded to a server.
Your file never leaves your browser. All processing happens on your device. Nothing is uploaded to any server.
What you can use it for
- Shrinking site images for better Core Web Vitals / PageSpeed
- Converting PNG logos and icons while keeping transparency
- Cutting bandwidth on image-heavy pages and galleries
