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.

3GP to MP4: transcode
3GP and MP4 are container/codec formats, so this re-encodes the video (a lossy step. Start from the best source you have). MP4 is broadly compatible, which helps when a player, editor or site won't accept 3GP.

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. No signup, no watermark, no daily cap.
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.
