Why Convert JPG to WebP?
Converting JPG to WebP is one of the fastest wins you can make for your website's performance. WebP is a modern image format developed by Google that delivers significantly smaller file sizes — typically up to 80% smaller than JPG — with the same visual quality.
If you run a Shopify store, a blog, or any website with images, switching to WebP directly improves your page load time and Google Core Web Vitals — which are part of Google's page experience signals.
The good news: converting JPG to WebP takes seconds with the right tool — and it's completely free. If you just want to convert a file right now, the free JPG to WebP converter does it in your browser, no signup.

WebP is the right choice for almost all web use cases. However, there are a few situations where you might keep JPG or PNG:
- Print production — WebP is web-only; use TIFF or high-quality JPG for print
- Email clients — some older email clients don't render WebP; use JPG for email
- Software with limited format support — some tools don't read WebP natively
- Transparent backgrounds — use WebP (it supports transparency), but PNG is also fine
WebP Browser Support in 2026
WebP is supported by 97%+ of browsers globally as of 2026. This includes Chrome, Firefox, Safari (since version 14), Edge, Opera, and all major mobile browsers. You don't need to worry about fallbacks for modern websites.
