Convert 3G2 to MP4.
3G2 is the video format old CDMA phones (Verizon, Sprint and the like) recorded in. Convert those clips to MP4 so they play on modern phones, browsers and editors.
The CDMA cousin of 3GP
If your old phone was on Verizon, Sprint or another CDMA carrier, its videos likely saved as .3g2 rather than the GSM world's .3gp. Same idea, slightly different wrapper — and the same problem today: those clips often refuse to open on current devices. Converting to MP4 brings them back to life and onto a format that'll keep working.

Moving old phone videos to the cloud? Convert them to MP4 first so they stay playable for years, wherever you open them.

Common questions
What is a 3G2 file?+
3G2 (3GPP2) is the video format used by older CDMA-network phones — the counterpart to 3GP on GSM phones. Both kept files tiny for slow networks, and both now trip up modern players and editors. MP4 holds the same video in a universal container.
Is it free?+
Yes — convert 3G2 to MP4 free, with no signup. Paid plans add larger files and bigger batches.
Is my file private?+
Uploads go to a private bucket, are converted, and auto-delete after 1 hour. Files never touch a third-party converter.
Will low-res clips look worse?+
No — we preserve the original resolution and frame rate. We can't add detail that wasn't captured, but nothing is thrown away.
