Convert 3GP to MP4.
3GP is the tiny video format old phones recorded in. Convert those clips to MP4 so they play in modern browsers, editors and players — and survive the next device you move them to.
Small files, big nostalgia
If you've ever pulled old videos off a feature phone or an early Android, you've met .3gp. It was designed for an era of slow networks and a few megabytes of storage, so it squeezes video and audio down hard. That made sense in 2007 — but today those clips often refuse to open in editors or browsers, and they're exactly the footage you don't want to lose.
Future-proofing
Converting to MP4 (H.264) does two things: it makes the clip play on everything now, and it moves it onto a format that'll still be supported in a decade. A good move before you back the memories up to the cloud or a new phone.
There's audio in there too
If the clip has speech worth keeping, hand the MP4 to TranscriptAI for a transcript.

Common questions
What is a 3GP file?+
3GP (and the CDMA-network variant 3G2) was the standard capture format for feature phones and early smartphones — built to keep files small for slow networks and tiny storage. It still plays on some devices but trips up modern editors and browsers.
Is it free?+
Yes — convert 3GP 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 old low-res clips look worse?+
No — we preserve the original resolution and frame rate. We can't add detail that was never captured, but nothing is thrown away.
