3GP to MP4 — No Upload, No Watermark

Why convert 3GP to MP4?

3GP is the format of early phone cameras and MMS clips — heavily compressed, low resolution and increasingly unplayable. Converting to MP4 is usually about rescuing family footage before the format becomes another dead end.

3GP was designed for early mobile networks: heavily compressed video and audio meant for feature phones. Old phone recordings and MMS archives are still full of it.

When 3GP → MP4 is the right move

Recovering old phone recordings from a backup or memory card.
Playing archived mobile clips on a current phone or computer.
Uploading old footage to a platform that rejects 3GP.

Quality, size and what changes

The clip is re-encoded to H.264 with AAC audio for universal playback. The original resolution and bitrate were tiny by modern standards, so the result stays soft — conversion restores access, not detail.

What you gain with MP4: Plays everywhere, streams well and is hardware-accelerated on virtually all devices.

How it works

Drop your 3GP file above and Morphio decodes it locally, then re-encodes it as MP4 using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle. See exactly how in-browser conversion works.

3GP to MP4 — frequently asked questions

How do I convert 3GP to MP4 without uploading the file?

Open the 3GP to MP4 page, drop your video on the drop zone and press convert. Morphio runs an FFmpeg build compiled to WebAssembly that runs inside the page, so the 3GP data never leaves your device and no server ever receives a copy.

Does converting 3GP to MP4 lose quality?

Audio and video tracks are re-encoded together, so the result stays in sync and plays on standard players. Converting 3GP to MP4 only rewrites the container and encoding you asked for — the source file on your disk is never modified.

Is the 3GP to MP4 converter free, and how big can the file be?

Yes. The free plan covers 10 conversions a day with files up to 200 MB and adds no watermark or sign-up. Morphio Pro ($5/month, or $29 once for lifetime access) removes the daily cap and raises the per-file limit to 5 GB.

Can the quality be improved?

No. The detail was never captured; the conversion only makes the existing footage playable everywhere.

Does audio come across?

Yes, the audio track is re-encoded to AAC and stays synchronised.
