Other ways on a Mac

For one file now and then you may not need FileFlip. These work with what’s already on your Mac.

Preview

Open the GIF in Preview, choose File → Export, pick JPEG-2000 from the Format menu and click Save. For several files, open them together, select all thumbnails in the sidebar and choose File → Export Selected Images.

Good for a few files now and then.

Terminal

The sips command converts images in place or into a new file.

sips -s format jp2 animation.gif \
  --out animation.jp2

Built into macOS and good for scripts. Run sips --formats to see what your macOS version can read and write.
