What is AVIF? Why Do You Need to Convert It?
AVIF (AV1 Image File Format) is a next-generation image format developed by the Alliance for Open Media. It offers outstanding compression — often 50% smaller file sizes compared to JPEG — with excellent visual quality. However, AVIF compatibility is still limited. Many older browsers, Windows applications, email clients, and social media platforms still do not support AVIF files natively.
That's why converting AVIF to a widely-supported format like JPG, PNG, or WebP is often necessary. JPG works everywhere and is ideal for photos. PNG preserves transparency for logos and graphics. WebP is a modern format supported by all major browsers with excellent compression.
AVIF vs JPG vs PNG vs WebP — Which Format Should You Use?
| Format | Best For | Transparency | Compatibility |
|---|---|---|---|
| AVIF | Modern web, tiny files | ✅ Yes | Limited (newer browsers) |
| JPG | Photos, universal sharing | ❌ No | Universal |
| PNG | Logos, graphics, icons | ✅ Yes | Universal |
| WebP | Web images, balancing quality & size | ✅ Yes | All modern browsers |
