About PNG to WebP Converter
Convert PNG images to WebP to get the best of both worlds: smaller file sizes and full transparency support. WebP lossless compression typically produces files 26% smaller than PNG, while lossy WebP at high quality is 25–34% smaller than JPEG. For web developers, PNG-to-WebP is one of the highest-impact performance optimisations available. WebP supports an alpha channel just like PNG, so transparent backgrounds are preserved perfectly in the output. Your browser handles the conversion — no upload, no server, full privacy. Batch convert your entire design asset library at once and download as a ZIP. Supported in all major browsers since 2020. For web developers, switching from PNG to WebP for image assets is one of the most straightforward performance improvements available — this tool makes the conversion instant, free, and private with no files sent to any external server. You can also use the quality slider to find the optimal balance between file size and visual fidelity for your specific use case.
