Method 5: Developer Solutions for Website Owners

If you're a website owner or developer serving WebP images to users, you can implement solutions to ensure compatibility across all browsers and devices.

Fallback Techniques:

1. Using the <picture> Element

The HTML5 <picture> element allows you to specify multiple image sources for different browser capabilities.

<picture>
  <source srcset="image.webp" type="image/webp">
  <source srcset="image.jpg" type="image/jpeg">
  <img src="image.jpg" alt="Description">
</picture>

With this approach, browsers that support WebP will load the WebP version, while others will automatically fall back to JPEG.

2. Server-Side Content Negotiation

Configure your server to deliver the appropriate image format based on the browser's Accept header:

• Apache configuration:

  RewriteEngine On
  RewriteCond %{HTTP_ACCEPT} image/webp
  RewriteCond %{DOCUMENT_ROOT}/$1.webp -f
  RewriteRule (.+)\.(jpe?g|png)$ $1.webp [T=image/webp,E=accept:1]

• Nginx configuration:

  location /images {
    if ($http_accept ~* "webp") {
      set $webp_suffix ".webp";
    }
    try_files $uri$webp_suffix $uri =404;
  }

3. JavaScript Detection

Use JavaScript to detect WebP support and serve the appropriate format:

function checkWebP(callback) {
  var webP = new Image();
  webP.onload = webP.onerror = function () {
    callback(webP.height == 2);
  };
  webP.src = 'data:image/webp;base64,UklGRjoAAABXRUJQVlA4IC4AAACyAgCdASoCAAIALmk0mk0iIiIiIgBoSygABc6WWgAA/veff/0PP8bA//LwYAAA';
}

checkWebP(function(support) {
  if (support) {
    // Use WebP images
    document.querySelector('.hero-image').src = 'hero.webp';
  } else {
    // Use fallback format
    document.querySelector('.hero-image').src = 'hero.jpg';
  }
});
