Frequently asked questions
Exactly how much smaller is WebP compared to PNG?
WebP is often 25–50% smaller than an equivalent PNG at comparable quality, which massively speeds up website page load times.
Do all web browsers support WebP?
Yes, all modern web browsers support it. However, if you are targeting extremely old systems, you may want to keep a PNG fallback.
Is transparency preserved in the new file?
Yes. WebP fully supports an alpha channel just like PNG, so edges remain transparent.
