AVIF vs JPG: modern compression or classic photos?
JPG is the default photo format everywhere. AVIF uses the AV1 codec to shrink images further while keeping excellent quality, but support is newer.
| AVIF | JPG | |
|---|---|---|
| Compression | Very efficient (AV1) | Lossy JPEG |
| File size | Often smallest | Baseline |
| Transparency | Yes | No |
| Browser support | Good, growing | Universal |
| Best for | Performance-focused sites | Sharing and printing anywhere |
Verdict
Use AVIF when every kilobyte counts on modern browsers. Keep JPG for email, print and apps that still expect classic JPEG files.
