WebP compresses far better than PNG while still supporting transparency, so this conversion often cuts a PNG to a fraction of its size with no visible change.

The saving is especially large on logos, icons and screenshots — exactly the images that tend to be stored as PNG and tend to be unnecessarily heavy.

As always, this is a conversion for the web. Keep a PNG copy of anything you may need to hand to someone else or submit to a portal.
