WEBP vs. AVIF: Technical Comparison
Understanding the technical differences between WEBP and AVIF helps you decide when conversion is beneficial and what to expect from the output.
- WEBP: Lossy and Lossless compression | Supports transparency | 25-35% smaller than JPEG at equivalent quality
- AVIF: Lossy and Lossless compression | Supports transparency | 30-50% smaller than JPEG, 20% smaller than WebP
- WEBP introduced: 2010 by Google
- AVIF introduced: 2019 by Alliance for Open Media (AOMedia)
- WEBP best for: web images, page speed optimization, modern web design
- AVIF best for: next-gen web images, maximum compression, HDR content
Both formats use lossy and lossless compression, so the conversion primarily changes the encoding method and compatibility profile.
100% Private: No File Uploads
Your images often contain personal photos, proprietary designs, confidential screenshots, or sensitive visual data. Uploading these to a cloud-based converter exposes them to third-party servers where they might be stored, logged, or accessed by unauthorized personnel. Our tool eliminates this risk entirely. The conversion uses your browser's native Canvas API and FileReader API — everything runs in client-side JavaScript. You can verify this by checking the Network tab in your browser's DevTools during conversion. You will see zero outbound requests. For maximum confidence, you can even disconnect from the internet after loading the page and the conversion will still work perfectly.
