JP2 vs AVIF: key differences
| JP2 | AVIF | |
|---|---|---|
| File type | lossy/lossless | lossy/lossless |
| Typical use | archival imaging, medical imaging, cinema | modern web, high-efficiency image delivery |
| Compatibility | Limited browser support; convert to JPG/PNG for the web. | Supported in Chrome, Firefox and recent Safari; not in older apps. |
Tips for a clean JP2 to AVIF conversion
- Limited browser support; convert to JPG/PNG for the web.
- Use the highest-quality source JP2 you have — converting a compressed file again cannot restore lost detail.
- If you only need a smaller file, try a lower resolution or bitrate instead of a different format.
- Keep the original JP2 until you have checked the converted AVIF opens the way you expect.
Frequently asked questions
