Convert AVI to 3GP Online

About AVI (source)

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 shows up:

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

About 3GP (target)

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 is used:

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

Converting AVI to 3GP

Pros

• Plays on very old phones and MMS clients

Cons

• Low resolution and bitrate caps
• Irrelevant for modern HD workflows

Caveats

• 3GP enforces mobile-era limits on resolution and bitrate. HD AVI sources will be downscaled. Use 3GP only when a target device explicitly requires it.
• 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.
