Convert a 3GP File to MP4
3GP to MP4 converter takes a video recorded on an old feature phone or early smartphone and gives it back as an MP4 you can play, edit, or upload anywhere. Upload the file and download the converted copy, no software or account setup beyond signing in.
What you get:
- A 3GP file converted to MP4, original resolution and framerate kept
- Files up to 2 GB in the free online tool on this page, with no set file size limit in the app
- bulk upload of multiple files, so several 3GP files convert in one batch
- A transcript of the audio, with speaker labels, in 100+ languages
- AI chat with any recording, so you can ask the converted video a question instead of watching it back
- Export the transcript as PDF, DOCX, TXT, SRT and VTT
- Free plan: 3 uploads, lifetime, each with the transcript and AI chat included
How to Convert 3GP to MP4
- Upload your 3GP file: from a computer, phone, or tablet. The free online tool on this page takes files up to 2 GB; the ScreenApp app has no set file size limit.
- Let it process: the file converts to MP4 and the audio transcribes at the same time. Both are ready in your library once processing finishes.
- Download the MP4: open the file and download it. The transcript, speaker labels, and AI chat are attached to the same recording.
The MP4 keeps the source file’s resolution and framerate, so a low-resolution feature phone video stays low-resolution: converting the container does not add detail that was never recorded. Transcript quality follows the audio: clear narration transcribes cleanly, and an old recording with wind noise or a tinny phone microphone will have more gaps. See how we measure accuracy.

Who Converts 3GP to MP4
Family historians dig up old feature phone footage, a child’s first steps or a grandparent’s birthday, recorded in 3GP because that was the only format the phone could save to. Converting to MP4 keeps the memory playable on current devices.
Mobile phone users carry old recordings from a Nokia, Sony Ericsson, or early Android phone that no modern app or editor opens. Converting to MP4 makes those clips playable again.
Video archivists and collectors work through boxes of old memory cards and phone backups. Converting a batch of 3GP files to MP4 turns an unplayable archive into something a browser or media player opens without a plugin.
Content creators pull an old mobile clip into a project for its nostalgic or low-fidelity look. Converting to MP4 first means it drops into Premiere Pro or Final Cut Pro without a format error.
Social media managers convert an old 3GP clip to MP4 before posting a throwback video, since Instagram, Facebook, TikTok, and YouTube all expect MP4 uploads.
