Convert Images to WebP & AVIF Online — Free

WebP and AVIF are modern image formats that deliver the same visual quality as JPEG and PNG at dramatically smaller file sizes. Smaller images mean faster page load times, better Google PageSpeed scores, and improved Core Web Vitals — all without any visible quality loss for your visitors.

Why Convert Images to WebP or AVIF?

25–80% Smaller Files

WebP and AVIF compress images significantly better than JPEG or PNG with no perceptible quality difference.

Better Core Web Vitals

Faster image loading directly improves your Largest Contentful Paint (LCP) score and Google PageSpeed ranking.

97%+ Browser Support

WebP is supported by virtually all modern browsers. AVIF support has reached 90%+ and is growing fast.

How It Works

  1. Step 1: Upload your images — drag and drop or click to select. PNG, JPG, JPEG, GIF, WebP, AVIF and more are supported.
  2. Step 2: Choose WebP or AVIF as the output format and set your quality level. We recommend 75–85 for most use cases.
  3. Step 3: Click Convert. Your browser processes everything locally using WebAssembly — then download files individually or as a ZIP.
