Why Convert PNG to WebP?
PNG files are often large because of their lossless compression. WebP supports both lossless and lossy compression — converting a PNG to WebP lossless typically reduces size by 26%, and lossy WebP can reduce PNG file sizes by 60-80% for photographic content while preserving transparency (alpha channel).
