When to use this conversion

WebP is a good middle ground when broad modern web support matters more than maximum AVIF compression.
The browser decodes AVIF and re-encodes WebP, so compare the preview and final file size.

Compare output formats

JPG

Photos and workflows that require the broadest app and platform support.

JPG removes transparency and uses lossy compression, so another re-encode can soften fine detail.

Convert to JPG

PNG

Screenshots, graphics, transparent images and files that will receive further editing.

PNG preserves detail and alpha, but photographic images can become much larger than JPG, WebP or AVIF.
