When to move from PNG to WebP

WebP is useful when a PNG is large because of photographic detail or complex transparency. Simple icons and flat graphics may already compress efficiently as PNG, so compare the result rather than assuming.

Straight answers

Frequently asked questions

Does WebP support transparent backgrounds?

Yes. WebP supports alpha transparency and the converter retains transparent pixels when supported.

Should I replace every PNG with WebP?

No. Compare file size and visual output. Small flat-colour PNGs can already be efficient.

Are design files stored on the server?

No. Selected image bytes are not intentionally transmitted to an image-processing server.
