Supports: 3GP, 3G2
3GP is the small, low-resolution container that 3G phones recorded to in the 2000s; M4V is Apple's MP4 variant, the format iTunes, the Apple TV app, QuickTime, and the iPhone/iPad libraries treat as a first-class movie. Convert 3GP to M4V when you want an old mobile clip to import and play cleanly across Apple software — but be clear up front: M4V is essentially an MP4 with the extension Apple prefers, so if you only need broad playback, our 3GP to MP4 converter produces the same H.264 video under the universal extension.
The video inside both is identical; the difference is the label and where each is treated as a native movie file.
| Property | M4V | MP4 |
|---|---|---|
| Developed by | Apple (with the iTunes video store, October 2005) | MPEG / ISO (ISO/IEC 14496-14, 2003) |
| Container | MPEG-4 Part 14 — structurally an MP4 | MPEG-4 Part 14 |
| Video codec we output | H.264 / AVC | H.264 / AVC |
| Audio codec we output | AAC | AAC |
| Optional DRM | FairPlay, on iTunes-Store purchases only | None |
| Treated as a "movie" by | iTunes, Apple TV app, QuickTime, iPhone/iPad | Most players, but not always Apple's TV app |
| Rename to the other extension | .m4v → .mp4 plays in most non-Apple players |
.mp4 → .m4v imports into Apple apps as a movie |
| Best when | You live in the Apple ecosystem | You need the widest possible playback |
.m4v extension Apple software treats as native..mp4..3gp (or .3g2) clip onto the page, or click "+ Add Files" to browse. Several files can be queued and converted with the same settings.The video stream is the same either way — H.264 inside an MPEG-4 container. Pick .m4v if you live in the Apple ecosystem: iTunes, the Apple TV app, and QuickTime treat M4V as a first-class movie. Pick .mp4 for the widest reach across Android, Windows, browsers, and consoles. Our 3GP to MP4 converter outputs the same H.264 video under the universal extension, and most players will open either file once you rename the extension.
No. A 3GP clip from a 3G phone was captured at low resolution and bitrate, and re-encoding to H.264 cannot recover detail that was never recorded — a tiny phone clip stays small and standard definition, not HD. What you gain is compatibility: the footage lands in a codec and container Apple's apps are built around. In our testing, leaving the Preset on "Very High" keeps the output visually indistinguishable from the source 3GP while making it import cleanly into an Apple library.
It depends on what the 3GP already holds. 3GP and M4V are both built on the MPEG-4 / ISO base media file format, so if the source already uses H.264 video, the stream can often be carried across with little re-encoding. If the 3GP uses older video like H.263 or MPEG-4 Part 2, it is re-encoded to H.264 — a more efficient, more compatible codec. Either way it is a lossy-to-lossy step, so nothing is regained, but quality stays high at the default preset.
No. FairPlay DRM only exists on M4V files bought from the iTunes Store. Files you create here are plain, DRM-free H.264-in-M4V — you can play, copy, and re-encode them freely, and renaming the file to .mp4 works in most non-Apple players.
3GP clips often carry AMR-NB or AMR-WB audio, the narrowband/wideband speech codecs built for 3G calls. M4V expects AAC, so the audio is re-encoded to AAC rather than copied verbatim. For voice-heavy phone clips this keeps the sound clean and Apple-compatible; if the 3GP already used AAC, the re-encode is a light generational step.
Apple devices do not natively open the 3GP container that old 3G phones recorded to, and support for AMR audio and H.263 video has thinned out across current Apple software. Converting to M4V wraps the footage in exactly the H.264-plus-AAC pairing inside the MP4-family container that the Apple TV, Photos, and QuickTime apps are built around, so the clip imports and plays without a third-party player.
Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.
