PNG to WebP — Free Online File Size Reducer
Convert PNG to the smaller WebP format — typically smaller at the same quality while preserving transparency, ideal for web performance optimisation. Batch, no upload, no watermark.
Converting PNG to WebP mainly reduces the file size of web images: WebP lossless mode also supports transparency and is typically smaller than PNG, resulting in faster load times. All major modern browsers support WebP; if you target very old environments, keep a PNG fallback. Conversion happens in your browser with no upload.
