Frequently Asked Questions
Can WebP preserve PNG alpha transparency securely?
Absolutely. WebP was engineered to handle complex alpha transparency channels perfectly. You benefit from alpha blending at a fraction of the PNG file size.
Why does my PNG look the same but weigh 60% less in WebP?
Google's WebP codec leverages predictive coding (predicting pixel values based on neighbors) which is far more advanced than PNG's older Deflate algorithm.
Will my confidential design assets be stored anywhere?
Never. Since our architecture relies entirely on Client-Side execution, we don't have databases tracking your assets. Once you close the tab, the data disappears.
Can I convert hundreds of PNG icons to WebP?
Yes, this is an excellent workflow. Simply bulk upload your icon folder and let your browser's threads convert them simultaneously in seconds.
