What is PNG?
PNG stores exact pixels with lossless compression and supports alpha transparency. It excels at flat-color graphics, but complex screenshots and photographic images may consume more bandwidth than necessary.
What is WebP?

When should I convert PNG to WebP?

The WebP format supports alpha transparency, and the converter retains decoded alpha data.
