M2TS to 3GP Converter
Processing entirely on your device — large files may take a moment.
M2TS is the Blu-ray and AVCHD camcorder transport stream — high-quality footage that most phones, social apps and editors refuse to open directly. Rescuing old phone videos means converting 3GP to MP4 before the memories become unreadable.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the M2TS format
M2TS is the transport stream of Blu-ray discs and AVCHD camcorders: MPEG-2 or H.264 video in fixed 188-byte packets, built for broadcast-style resilience rather than compactness. Copy a camcorder's clips off its card and you are holding M2TS files; so is most of a decrypted Blu-ray folder structure.
The format plays in VLC and a handful of editors, but phones, social platforms and web apps reject it. Converting to MP4 is the standard hand-off: the video re-encodes to H.264 at your chosen quality and the result plays literally everywhere.
+ Strengths
- ✓Broadcast-grade error resilience
- ✓Native to Blu-ray and AVCHD cameras
- ✓Carries high-bitrate, high-quality footage
! Limitations
- −Rejected by phones, web players and social platforms
- −Packet overhead inflates file size
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

Frequently asked questions
Is this M2TS to 3GP 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 M2TS to 3GP?
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.
Does converting M2TS to 3GP 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.
