What is the MMF file format used for?

MMF is a mobile audio format used for storing synthetic music commands and small embedded audio samples, commonly for ringtones and alerts on legacy feature phones.

Can I use MMF files on modern smartphones?

MMF files require a SMAF/MMF-compatible decoder or device and are generally not supported on most modern smartphones or platforms.

Will the video and metadata from my MOV file be preserved after conversion to MMF?

No, the conversion only extracts audio content. Multi-track video, metadata, and timecode information from MOV files cannot be preserved in the MMF format.

Select MMF as the output audio format for your conversion.
Optionally trim or downmix audio if the tool supports editing features.
Click the convert button to start transformation into the MMF format.
Download the converted MMF file for use on SMAF/MMF compatible devices.

Key Features

Converts audio from MOV multimedia video container files to MMF mobile audio format.
Produces very small file sizes optimized for low-memory legacy mobile phones.
Supports sequenced synthesis commands and embedded low-bitrate samples in MMF.
Suitable for creating ringtones, alerts, and short sound effects from video audio tracks.
Browser-based and easy to use without requiring special software installation.

Examples

Extract a short music hook from a MOV file exported by a video editor and convert it to MMF for use as a ringtone on legacy phones.
Convert a brief user interface sound effect embedded in a MOV project into an MMF file for deployment in an early mobile game.
Archive legacy ringtone collections originally created from MOV audio tracks for compatibility and preservation.

Common Use Cases

Creating ringtones and short alert tones from MOV audio tracks for legacy feature phones.
Converting short game or app sound effects from post-production MOV files into compact MMF format for older mobile platforms.
Archiving or testing legacy mobile ringtone collections made from video or audio assets.

Tips & Best Practices

Use this tool to produce audio clips that are brief and optimized for low-memory devices.
Be aware that MMF format supports limited audio fidelity and simple synthesized or embedded sampled audio.
Ensure your MOV files do not contain unsupported codecs that may prevent proper decoding before conversion.
Understand that multi-track audio and metadata from MOV will not be preserved in the MMF output.
Test converted MMF files on actual target devices or compatible emulators to verify playback.

Limitations

Converted MMF files have significantly reduced audio quality compared to original MOV due to low-fidelity format constraints.
MMF format requires SMAF-compatible decoders or devices and is not widely supported on modern platforms.
MOV source files with proprietary or high-bitrate codecs may need proper handling before conversion.
Multi-track audio, metadata, and timecode information present in MOV containers are lost during conversion.
MMF's restricted instrument sets and channel capabilities limit reproduction of complex or multi-channel audio.
