Why convert PNG to WebP?

PNG is great for the design pipeline — it's lossless, supports transparency, and survives any number of round-trips without quality drift. It's rough once you ship the asset. A 500 KB marketing PNG is often 200 KB as a WebP at the same visual quality, and every modern browser (Chrome, Edge, Safari, Firefox) renders it natively.

Convert when you're shipping the asset to a website, an app, or a CDN. Keep the PNG when you need to hand the file to someone who'll open it in Word, an older imaging tool, or an email-attachment workflow that hasn't caught up with WebP yet. Transparency carries through this tool — your alpha channel is preserved.
