Best Image Format for Websites

For most website photos, WebP or a high-quality JPEG is a solid choice. WebP typically reduces file size by 25–35% compared to JPEG at similar quality, which speeds up page loads and improves user experience.

Use PNG for images that need transparency (e.g., logos, icons). Prefer WebP with a PNG fallback when you want both transparency and smaller files. AVIF is gaining support and can offer even better compression but is not yet universal.

Serve images in the format the browser supports (e.g., via picture or conditional delivery) and always optimize file size. Hosting your images on a fast, reliable service like Image Store helps ensure they load quickly when embedded on your site.
