Why convert a PNG file to WebP?
A PNG is heavy for a photo, and some online forms refuse it.
WebP makes website images lighter with no visible loss, and supports transparency.
What about quality?
WebP is a lossy format. Morfile uses a high quality by default: the difference isn’t visible to the naked eye. You can adjust it in the app.
