3GP 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 3GP format, this page is the shortcut: 3GP is the ultra-compressed video format old feature phones used. Modern players often cannot open these recordings.
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 3GP compares to H.264
| 3GP | H.264 | |
|---|---|---|
| Compression | H.263 / baseline H.264 + AMR | H.264/AVC (lossy) |
| Best for | Old mobile footage | Pipeline exchange, remuxing into MP4 |

About the 3GP format
3GP is the 3GPP mobile video format from the pre-smartphone era, designed for 2G/3G bandwidth: low resolution (typically 176×144 to 640×480), H.263 or baseline H.264 video, and AMR audio. Every early camera phone recorded in it, and MMS messaging depended on its small footprint.
It is strictly a conversion source today: pull the videos off an old phone, convert to MP4, and enjoy a resolution upgrade from better scaling alone. Quality expectations should stay low — the pixels were never there.
+Strengths
- ✓Tiny files for its era
- ✓Plays on old feature phones
!Limitations
- −Very low resolution and quality ceiling
- −Obsolete; no modern platform wants it
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

Frequently asked questions
Is this 3GP 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 3GP 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.
Does converting 3GP to H.264 re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
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 3GP file has multiple audio tracks, the first one is used.
