M1V to 3G2 Converter
Processing entirely on your device — large files may take a moment.
MPEG-1 Video Stream and 3GPP2 Mobile Video exist for different jobs: M1V is a raw MPEG-1 video elementary stream — VCD-era video without a container. Converting 3G2 to MP4 rescues old phone videos for modern screens.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the M1V format
M1V is a bare MPEG-1 video elementary stream — the video of Video-CDs without any container. MPEG-1's 352x288 VCD resolution looks prehistoric now, but the decoder is built into literally everything, which is why the format refuses to die.
Elementary streams confuse modern players (no timestamps container), so the fix is wrapping into MP4 — the video decodes through ffmpeg and gains proper seeking.
+ Strengths
- ✓Plays on literally any hardware
- ✓Simple to decode — zero surprises
- ✓Common on old CD rips
! Limitations
- −VCD-grade resolution only
- −No timestamps without a container
- −No audio track inside M1V
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
Why convert M1V to 3G2?
Converting makes sense where the strengths of 3G2 meet what M1V cannot give you. Tiny files for its era Meanwhile VCD-grade resolution only One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this M1V to 3G2 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 M1V to 3G2?
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 M1V to 3G2 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.
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.
