How to convert PSD to JPEG 2000 with FileFlip
Select the PSD files
In Finder or on the Desktop. One file, or a whole folder with ⌘ A.
Press ⌥ F
FileFlip opens next to the selection and lists the formats it can make from PSD. Type “JPEG 2000” to jump to it.

The JPEG 2000 files appear next to the originals with the same names. The PSD files stay as they are.
PSD and JPEG 2000
Most people and websites can’t open a Photoshop file, so it has to be flattened into a regular image to share. Some archives and professional imaging systems ask for JPEG 2000.
What changes when you convert
- JPEG 2000 can store the image either lossy or lossless.
- The layers are flattened into a single image.

sips -s format jp2 design.psd \
--out design.jp2Built into macOS and good for scripts. Run sips --formats to see what your macOS version can read and write.
