When to Convert PNG to WebP
WebP is best when you want smaller site assets while keeping modern browser support.
Use WebP for transparent web assets
WebP supports alpha transparency, so many transparent PNG graphics can become smaller WebP files.
Keep PNG for maximum app support
Some older tools and upload fields still prefer PNG. Keep PNG when the receiving app does not support WebP.
Check visual quality after compression
WebP can use lossy compression. Review fine text, sharp edges, and gradients before replacing production assets.
