Use Progressive Enhancement

Always provide JPG fallbacks for browsers that don't support WebP:

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

Batch Processing

For large numbers of images, use batch processing tools or scripts to automate the conversion process. This ensures consistency and saves time.

Test Across Browsers

Always test your WebP images across different browsers and devices to ensure they display correctly and that the file size savings are worth the conversion effort.

Monitor Performance

Use tools like Google PageSpeed Insights, GTmetrix, or WebPageTest to measure the performance improvements after converting your images.

Common Issues and Solutions

Issue: WebP files are larger than JPG

Solution: This usually happens with already highly compressed JPG files or when using lossless WebP compression. Try using lossy compression with quality settings between 75-85.

Issue: Images don't display in older browsers

Solution: Always use the HTML picture element to provide JPG fallbacks for browsers that don't support WebP.

Issue: Quality loss is too noticeable

Solution: Increase the quality setting to 85-90, or use lossless compression for images where quality is critical.

Issue: Conversion process is slow

Solution: Use online converters like WebP2Me for individual images, or command-line tools for batch processing large numbers of files.
