Need Audio from Old 3G2 Videos?

3G2 files are video recordings from older CDMA mobile phones. If you have voice memos, recorded calls, or video clips with audio you want to keep, extracting to M4A gives you a modern, high-quality audio format.

M4A uses AAC encoding, delivering better quality than MP3 at similar file sizes. It plays natively on iPhones, iTunes, and most modern devices.

How to Convert 3G2 to M4A

Upload your 3G2 file - Select your mobile video file
Confirm M4A output - Extracts audio with AAC encoding
Download your file - Ready for any modern player

Conversion happens in your browser. Fast, private, no installation required.

Why Choose M4A Format?

Better quality - AAC encoding outperforms MP3 at same bitrates
Smaller files - Efficient compression saves storage space
Apple compatible - Native support on iPhone, iPad, iTunes
Modern standard - Widely supported across devices

Common Uses for 3G2 Audio Extraction

Preserve Voice Recordings

Old phone videos often contain irreplaceable voice recordings. Extract them to M4A before the original files become inaccessible.

Create Audio Archives

Strip away the video when you only need the sound. A 50MB video might become a 5MB audio file.

Need Other Formats?

We support multiple output options from 3G2 files:

3G2 to MP3 - Maximum compatibility
3G2 to MP4 - Keep video, modern format

Works on Any Device

Browser-based conversion with no software to install:

Windows, Mac, Linux
Chrome, Firefox, Safari, Edge
iPhone, iPad, Android

Pro Tip

If you have many old 3G2 files, batch convert them now. Finding software that plays 3G2 natively is becoming difficult as the format fades from use.

Common Mistake

Expecting high-fidelity audio from old phone recordings. 3G2 files from the 2000s used aggressive compression. The extracted M4A reflects this source limitation.

Best For

Extracting voice recordings, memos, or audio content from archived CDMA phone videos. Ideal when you need Apple-compatible output.

Not Recommended

Not ideal if you need maximum compatibility with older devices. Use MP3 instead for vintage hardware or car stereos that do not support M4A.

Frequently Asked Questions

3G2 is a multimedia format from CDMA mobile phones (Verizon, Sprint era). It contains video and audio optimized for 3G networks. Most modern devices cannot play 3G2 directly.

M4A uses AAC encoding which sounds better than MP3 at the same file size. A 128kbps M4A equals roughly 192kbps MP3 in quality. M4A also works natively with Apple devices.

Output quality depends on your source 3G2. Old phone recordings typically used low bitrates for bandwidth. We extract at original quality without degradation.

Yes. Android supports M4A playback. Most music apps and the default player handle M4A files without issues.

Most 3G2 files convert in seconds. Larger files may take slightly longer. Audio extraction is faster than full video conversion.
