What is the MMF format used for?

MMF is a mobile audio format designed for ringtones and short alerts, primarily on legacy feature phones, storing sequenced synthesis and small sampled audio.

Can I convert full-length audio or video to MMF?

No, MMF is optimized for short, low-fidelity audio clips and does not support long or complex audio content.
