MIFF at a glance
MIFF
Convert to MIFF when ImageMagick or a related processing stack is the main consumer and you want a tool-native working format.
It is useful as an intermediate in automated imaging pipelines.
DOCM at a glance
DOCM
Convert to DOCM when the output must retain or deliver Word macro functionality, such as automated forms, button-driven templates, mail-merge helpers, or internal workflow documents with embedded VBA.
It is appropriate only when the recipient environment expects macro-enabled Word files and can handle the associated trust model.
If macros are not needed, DOCX is the safer and more portable choice.
