About the WebP Format
WebP is a modern image format developed by Google that provides superior lossless and lossy compression for images on the web. WebP images are typically 25–34% smaller than comparable JPEG files and 26% smaller than PNG files, while maintaining equivalent visual quality. The format supports transparency (alpha channel), animation, and both lossy and lossless compression modes. WebP is supported by all major browsers and is increasingly adopted across the web for its excellent balance of quality and file size.
Features
Near-Zero CO₂
Server-based converters upload your file, process it remotely, and send it back — consuming network and data-centre energy on every request. WebConverter runs entirely on your device, so the only energy used is your local CPU. No data transfer, no server electricity.
Install for Offline Use
WebConverter works offline as a Progressive Web App. Click "Add to Home Screen" on mobile or the install button in your browser's address bar. Once installed, you can convert files without any internet connection.
