Why Convert PNG to WebP?
WebP offers the best of both worlds: it supports transparency like PNG, but with dramatically better compression. WebP files with transparency are typically 60-80% smaller than equivalent PNGs.
For web developers and designers, this means you can serve transparent images (logos, icons, UI elements) at a fraction of the file size. This directly improves page load speed and Core Web Vitals scores.

Frequently Asked Questions
Does WebP preserve transparency?▾
Yes. Unlike JPG, WebP fully supports alpha channel transparency. Your transparent PNG backgrounds will be preserved in the WebP output.
How much smaller will my files be?▾
WebP files are typically 60-80% smaller than PNG for images with transparency, and 30-50% smaller for opaque images. The exact savings depend on image content.
Are my files uploaded to a server?▾
No. Everything runs in your browser using the Canvas API. Your files never leave your device.
Do all browsers support WebP?▾
Yes. All major browsers — Chrome, Firefox, Safari 14+, Edge, and Opera — support WebP. The only holdouts are very old browser versions that represent less than 3% of traffic.
