JP2 vs PNG: What Is the Difference?
JP2 (JPEG 2000) and PNG differ in compression and software support. Both formats can include transparency.
| Feature | JP2 | PNG |
|---|---|---|
| Compatibility | Less widely supported by everyday apps and browsers | Widely supported by browsers and image editors |
| Compression | Supports lossy and lossless compression | Uses lossless compression |
| Transparency | Can include transparency | Supports transparency |
PNG uses lossless compression, but conversion does not restore detail already missing from a JP2 image. Keep the original JP2 if its metadata or specialist image features matter.
