A lossy quality setting between 80% and 85% provides near-lossless visual appearance with up to 60% smaller file sizes than standard JPEG assets.

Because no shipping browser can encode AVIF from a canvas, and everything here runs in your browser. Browsers decode AVIF widely but they do not expose an encoder, so a purely client-side tool cannot produce one without shipping a large WebAssembly encoder and spending significantly more time and memory per image. Worse, when a browser is asked for a format it cannot encode it silently returns a PNG instead — so the honest option today is WebP, which every current browser both encodes and decodes.

Match it to the content, not to a preference for quality. Screenshots, logos, diagrams and anything with crisp edges or flat colour belong in lossless, where WebP typically beats PNG by 20-30% with pixel-identical output. Photographs belong in lossy, where it beats JPEG substantially at the same perceived quality. Choosing lossless for a photograph produces a file larger than the JPEG you started with, which is the most common way this setting is used wrongly.

Rarely. As with JPEG, lossy WebP has already discarded the detail that compression targets, so a second pass costs quality for a modest saving. The exception is a file exported at a needlessly high quality — something saved at 95 will drop to 80 with real savings and little visible change. If the file is already modest, resizing to the dimensions you actually display is the better move.
