Best Practices for WebP Optimization

• Use lossy compression for photos and lossless for graphics

• Test image quality side-by-side before deployment

• Keep original JPGs for backup or fallbacks

• Optimize images using tools like ImageOptim, Squoosh, or TinyPNG

• Implement lazy loading and responsive image techniques

SEO Considerations for Using WebP Images

• Add correct type="image/webp" in HTML <source> tags

• Use <picture> elements for fallback compatibility:

html
<picture>
  <source srcset="image.webp" type="image/webp">
  <img src="image.jpg" alt="Descriptive Alt Text">
</picture>

• Leverage CDNs like Cloudflare or Bunny.net to serve WebP automatically

• Validate WebP delivery using Chrome DevTools or PageSpeed Insights

Troubleshooting Common Conversion Issues

Issue	Solution
WebP file size is larger than JPG	Lower the quality setting or switch to lossy mode
Browser doesn’t support WebP	Use <picture> element for fallback
Image appears distorted	Recheck compression settings and source quality
Plugin not converting in WordPress	Clear cache, recheck plugin settings
