Convert 3GP to AVI Online

About 3GP (source)

3GP is a mobile multimedia format defined for 3G phones. It uses low resolutions and bitrates suited to MMS and early smartphones. Modern phones record MP4 instead, but 3GP still appears in old phone backups and carrier MMS attachments.

Where 3GP shows up:

• Old mobile phone video clips
• MMS attachments from feature phones
• Legacy surveillance on low-end devices
• Markets where bandwidth was severely limited

About AVI (target)

AVI (Audio Video Interleave) is a legacy Microsoft container from the 1990s. It appears in old camcorder exports, downloaded videos, and industrial capture systems. AVI often contains DivX, Xvid, or uncompressed video with MP3 or PCM audio.

Where AVI is used:

• Legacy security DVR and industrial camera exports
• Old downloads and camcorder archives
• Software that never added MP4 support
• Embedded systems with AVI-only playback

Converting 3GP to AVI

Pros

• Runs on legacy AVI-only software and hardware

Cons

• Obsolete for modern sharing and streaming
• Poor subtitle and multi-track support

Caveats

• AVI is legacy output. Expect MPEG-4 Part 2 or Xvid-style video unless you choose H.264 in settings. Multi-track audio and modern subtitles are poorly supported in AVI.
• Muxara maps the primary video and audio streams. Extra subtitle or audio tracks may not carry over unless you choose subtitle handling in the converter settings.
• Uploads are processed on dedicated workers and deleted within 24 hours. For offline batch work, use the free Muxara Mac app.
