Convert 3GP to WebM 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 WebM (target)

WebM is a web-focused container designed for HTML5 video. It usually holds VP8 or VP9 video with Opus or Vorbis audio. Chrome, Firefox, and Edge play WebM natively; Safari support improved in recent versions. Screen recorders and web apps often export WebM.

Where WebM is used:

• HTML5 <video> players on websites
• Chrome and OBS screen recordings
• Discord and web app exports
• Open, royalty-free web delivery

Converting 3GP to WebM

Pros

• Often smaller than 3GP at similar quality for web use
• Royalty-free and native in Chrome and Firefox

Cons

• Weaker support on Apple devices and older TVs
• Requires transcoding from most 3GP sources

Caveats

• WebM output typically uses VP9 and Opus for efficient web delivery. Safari and older smart TVs may need an MP4 fallback alongside WebM.
• 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.
