Why Convert Images to WebP?
1. Upload your image
Upload any JPG, PNG, or GIF image. The tool shows the original file size so you can compare the size reduction after conversion.
2. Set quality level
Adjust quality between 1–100. For most web images, 80–85% is the sweet spot — visually identical to the original but significantly smaller.
3. Download the WebP
Download the converted WebP file and replace the original on your website. All conversion happens in your browser — your images are never uploaded to any server.

Impact on Core Web Vitals & SEO
Largest Contentful Paint (LCP)
WebP images load 25–35% faster than JPG equivalents, directly improving your LCP score — one of Google's three Core Web Vitals used for ranking.
Total Page Weight
Switching all images from JPG to WebP reduces your page's total transfer size, improving load times especially on mobile and slow connections.
Bandwidth Cost
For high-traffic sites, WebP reduces CDN bandwidth consumption significantly, lowering hosting costs at scale.
Google PageSpeed Insights
PageSpeed Insights specifically flags "Serve images in next-gen formats" as an opportunity — converting to WebP resolves this recommendation.
