MPEG2 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 MPEG2 format, this page is the shortcut: MPEG2 names the DVD/broadcast generation of MPEG streams — the same program stream container MPG files use.
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 MPEG2 compares to H.264
| MPEG2 | H.264 | |
|---|---|---|
| Compression | MPEG-1 / MPEG-2 | H.264/AVC (lossy) |
| Best for | Legacy disc and capture video | Pipeline exchange, remuxing into MP4 |

About the MPEG2 format
MPG (MPEG program stream) usually means MPEG-1 or MPEG-2 video — the codecs of VCD, SVCD and DVD, and of countless home video captures in the 1990s and 2000s. MPEG-1 tops out around VHS-grade 352×288; MPEG-2 delivers proper standard definition and still runs inside broadcast and DVD infrastructure.
Playback compatibility is its superpower: MPEG-1/2 decode paths exist in every player and hardware made this century. Quality-to-bitrate efficiency, however, is a generation behind H.264 — converting old MPG files to MP4 typically halves their size.
+Strengths
- ✓Decodes on essentially every player and device
- ✓Simple, battle-tested standard
!Limitations
- −Inefficient codecs by modern standards
- −MPEG-1 is VHS-grade at best
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 MPEG2 to H.264?
Converting makes sense where the strengths of H.264 meet what MPEG2 cannot give you. The universal codec — plays everywhere once wrapped Meanwhile Inefficient codecs by modern standards One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this MPEG2 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 MPEG2 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 MPEG2 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 MPEG2 file has multiple audio tracks, the first one is used.
