About This Operation

What to Expect

WebP can be a practical delivery format for PNG graphics and images when the destination supports modern web formats.

The current WebP output uses lossy encoding, so flat colors, text edges and fine graphics may change. Supported PNG transparency can be represented in WebP.

Supported input

Accepts valid, single-frame PNG content whose file type matches the selected source format.

Output

Produces a still WebP and retains supported alpha rather than forcing a background.
