Format referenceWhy convert DNG to PNG?
- A separate copy makes it easier to compare the old and new behavior.
- Conversion is useful when the destination has a strict format requirement.
- A converted copy keeps the original file intact for comparison and future edits.
- The output can be tested in the destination workflow before the original is archived.
Will quality change?
Lossless PNG output protects the decoded image from further compression damage. Keep the source if you need the original encoding. Review the file in the application where it will be used.
