When to convert PNG to WebP
WebP is a modern format supporting both lossless and lossy compression plus transparency, so it typically produces smaller files than PNG at the same visual quality. That makes PNG→WebP ideal for speeding up websites without giving up transparent backgrounds or crisp edges.
The main trade-off is compatibility: every current browser supports WebP, but some older apps and design tools still expect PNG. If you need maximum compatibility or plan to edit in legacy software, keep the PNG.
