Why convert to WebP?
WebP is a modern image format created by Google that produces significantly smaller files than JPG and PNG at the same visual quality. Smaller images mean faster page loads, better Core Web Vitals (especially Largest Contentful Paint), lower bandwidth costs and better SEO. Google PageSpeed Insights specifically recommends serving images in next-gen formats like WebP.

Choosing a quality setting
- 85% (default): excellent quality and big savings, ideal for websites.
- 90–95%: hero images and photography portfolios.
- 70–80%: thumbnails, blog images and product grids.
Using WebP on your website
With a fallback for very old browsers:
<picture>
<source srcset="photo.webp" type="image/webp">
<img src="photo.jpg" alt="Description" width="800" height="600">
</picture>
WordPress (5.8+), Shopify, Next.js, Webflow and most modern CMSs accept WebP uploads directly.
Tips
- Convert originals, not already-compressed images, for the best quality.
- Always set width and height on
<img>tags to avoid layout shift. - Need it even smaller? Run the WebP through the Image Compressor with a maximum width.
