Frequently Asked Questions
- How much smaller is WebP than JPG?
- WebP typically saves 25–35% file size compared to JPG at similar quality. For a 200 KB JPG, WebP might be 130–150 KB. The savings add up across many images. All modern browsers support WebP; use JPG fallback for older ones.
- How do I add WebP with JPG fallback?
- Use the HTML picture element. Put the WebP source first, then the JPG as fallback. Browsers that support WebP will use it; others get JPG. No JavaScript needed. Pngtm.com can convert your images to WebP for free.
- Does WebP support transparency?
- Yes. WebP supports transparency like PNG, with smaller file size. Use WebP for images that need transparent backgrounds. Not all older programs support WebP—convert to PNG or JPG when sharing outside the web.
