How to Convert Images to WebP — Faster Websites & Core Web Vitals

How to Convert Images to WebP in 3 Steps

1. 1

   Upload your images

   Upload JPG, PNG, or GIF images. Batch convert up to 20 files at once.

2. 2

   Set WebP quality

   Choose quality level (default: 80%). WebP at 80% typically looks identical to JPEG at 90% while being significantly smaller.

3. 3

   Download WebP files

   Download individual WebP files or all as a ZIP archive.

For a website with 20 page images, switching to WebP typically saves 1–3 MB per page load — a massive speed improvement.

Browser Support — Is WebP Safe to Use?

WebP browser support as of 2025:

- Chrome (all versions) ✓ - Firefox (since 2019) ✓ - Safari (since iOS 14/macOS Big Sur, 2020) ✓ - Edge (all modern versions) ✓ - Samsung Internet ✓

This covers 97%+ of global web users. For the 3% on very old browsers, provide a JPEG fallback using the HTML `<picture>` element:

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

  Convert before uploading to your CMS — most platforms store the file as-is, so upload WebP directly.
