3G2 to H.264 Converter
Processing entirely on your device — large files may take a moment.
Convert a .h264 dump to MP4 to add timestamps and player compatibility, or extract a raw H.264 stream from MP4 for pipeline use. If your files are still in 3G2 format, this page is the shortcut: 3G2 is the CDMA-era mobile video format — tiny, low-resolution clips from old feature phones.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.
How 3G2 compares to H.264
| 3G2 | H.264 | |
|---|---|---|
| Compression | H.263 / baseline H.264 | H.264/AVC (lossy) |
| Best for | Old mobile clips | Pipeline exchange, remuxing into MP4 |

About the 3G2 format
3G2 is the 3GPP2 variant of the mobile video format family, born on CDMA networks (Verizon, KDDI) where 3GP ruled GSM sides. Structurally it is a cousin of MP4 carrying H.263 or H.264 baseline video with QCELP/EVRC or AMR audio.
It shares 3GP's fate: low-resolution clips trapped on old phones. Conversion to MP4 is lossless in spirit — the pixels simply move into a container every modern device accepts.
+Strengths
- ✓Tiny files for its era
- ✓Structurally close to MP4 — clean conversions
!Limitations
- −Low resolution and quality ceiling
- −Obsolete outside old CDMA phones
About the H.264 format
H.264 (also called AVC) is the video codec the entire internet settled on: Blu-ray, YouTube, broadcast TV, every phone camera. A .h264 file is that codec's raw bitstream with no container — no timestamps, no audio, no metadata, just compressed frames back to back. Cameras and capture pipelines emit it because it is the codec's native shape.
Players struggle with raw streams precisely because there is no container to carry timing information. Wrapping H.264 into MP4 or MKV adds timestamps, duration and (optionally) audio tracks — the picture itself is untouched, since remuxing copies the compressed frames as-is.
+Strengths
- ✓The universal codec — plays everywhere once wrapped
- ✓Native output of cameras and capture cards
- ✓Remuxing is lossless (stream copy)
!Limitations
- −No container: no timestamps, no audio, no duration
- −Most players refuse or mis-time raw streams
Why convert 3G2 to H.264?
Converting makes sense where the strengths of H.264 meet what 3G2 cannot give you. The universal codec — plays everywhere once wrapped Meanwhile Low resolution and quality ceiling One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this 3G2 to H.264 converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for 3G2 to H.264?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Why is video conversion slower than image conversion?
Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of H.264, staying in sync with the video. If your 3G2 file has multiple audio tracks, the first one is used.
