How do Cloudinary Edge Functions optimize images at Vercel Edge?

Automatic WebP/AVIF conversion based on Accept header reduces image size 70%. Real-time transformations (resize/crop) without origin server load. Global CDN caching eliminates rebuilds. Node.js middleware applies optimizations transparently.

‍Example:-

Code

app.use((req, res, next) => {
  if (req.path.match(/\.(jpg|png)$/)) {
    res.redirect(`https://res.cloudinary.com/demo/image/fetch/w_800,q_auto,f_auto/${req.path}`);
  } else next();
});
