| Consideration | AVIF | JPG |
|---|---|---|
| Best fit | Modern web delivery | Sharing and broad compatibility |
| Transparency | Supported | Not supported |
| Compression | Highly efficient | Widely supported and predictable |
| Older software | May fail | Usually supported |
AVIF is efficient for modern delivery, but older applications and strict upload systems may not accept it. JPG improves compatibility at the cost of transparency and another lossy encoding step.
JPG cannot store transparency. Transparent pixels are flattened onto the background colour selected in the converter.
JPG is lossy, so some information is discarded. Start with a high quality setting and inspect the result.
Current major browsers generally support AVIF, but older browsers may not. The tool reports a clear error when local decoding is unavailable.
