Why convert PNG to WebP?

WebP can substantially reduce the size of photographic or complex PNG images, which can make web pages and online portfolios faster to transfer.

WebP supports transparency, so logos and graphics can keep transparent pixels. A lossy quality setting may soften fine text or sharp edges, so inspect the preview.

Transparency, quality, and support

Transparent and partially transparent PNG pixels are retained in WebP output. The quality control affects lossy image detail and file size.

Modern browsers support WebP, but some older desktop applications may still require PNG. The newly encoded file does not copy PNG metadata.
