Frequently Asked Questions
Is WebP better than PNG?
WebP is typically 25-35% smaller than PNG at the same visual quality, while also supporting transparency (alpha channel). For web use, WebP is almost always a better choice than PNG unless you need maximum browser compatibility.
Do all browsers support WebP?
Yes. All modern browsers support WebP: Chrome (since 2014), Firefox (since 2019), Safari (since 2020), and Edge. Over 97% of global users are on WebP-supported browsers. For legacy IE11 support, keep a JPEG fallback.
Is my image uploaded to a server?
No. All conversion is done using the HTML Canvas API directly in your browser. Your images never leave your device and are never stored on any server.
