Need help?3GP to M2TS Converter
3GP is the low-resolution mobile container 3G phones recorded to; M2TS is the HD MPEG-2 Transport Stream container used by Blu-ray discs and AVCHD camcorders. This conversion re-wraps and transcodes a small phone clip into the container a Blu-ray or AVCHD authoring tool expects — the realistic reason to target M2TS at all. If you just want a clip that plays everywhere, convert 3GP to MP4 instead; M2TS only makes sense when an authoring tool or HD player specifically demands it.
Will This Make My Video HD?
No — and this is the honest part most converters skip. A 3GP clip was captured at phone resolution (often 176×144, 320×240, or up to 640×480 on later devices). Putting it in an HD container does not add detail that was never recorded; upscaling to 1920×1080 only stretches the same pixels. M2TS is capable of carrying 1080i/720p, but the source caps the real quality. Also note: a single .m2ts file is not a playable Blu-ray or AVCHD disc — set-top players need the full BDMV/AVCHD folder structure that an authoring tool builds around the stream.

How to Convert 3GP to M2TS
- Upload Your 3GP File: Drag and drop your .3gp (or .3g2) clip onto the page, or click "Add Files." Several clips can be queued and converted with the same settings.
- Pick Video Codec and Preset: Under Advanced Options, leave Video Codec on H.264 for AVCHD compatibility (MPEG-2 and H.265 are also offered), and set the quality Preset — "Very High" is the default.
- Set Resolution and Trim (Optional): Use the resolution controls to keep the original size or pick a preset, and use Trim's Time Range to export only part of the clip. Remember that upscaling will not recover lost detail.
- Convert and Download: Click Convert and download your .m2ts file. Files upload over an encrypted connection, are processed on our servers, and are deleted automatically after a few hours — no sign-up, no watermark.
Frequently Asked Questions
Why would I convert 3GP to M2TS instead of MP4?
Only when a tool requires it. M2TS is the container Blu-ray and AVCHD authoring software ingests, so if you are mastering a disc or feeding an HD-camcorder workflow, M2TS is the right target. For everything else — phones, browsers, editors, social uploads — MP4 with H.264 is smaller, universal, and simpler, so 3GP to MP4 is usually the better choice.
Does converting 3GP to M2TS improve the video quality?
No. The output can sit inside an HD container, but quality is fixed by what the phone originally captured. Re-encoding a lossy 3GP clip cannot add detail, and an aggressive transcode can lose a little. The goal of this conversion is container compatibility, not a quality upgrade.
Is a .m2ts file the same as a Blu-ray or AVCHD disc?
No. A bare .m2ts file is just the transport stream. A disc that a set-top Blu-ray or AVCHD player will recognize also needs the surrounding BDMV/AVCHD folder structure and index files, which an authoring tool generates. Use the .m2ts file as the input to that tool, not as the finished disc.
What happens to my 3GP's AMR or AAC audio?
It gets re-encoded. AVCHD-compliant M2TS expects Dolby Digital (AC-3) or LPCM audio, not the AMR or AAC streams a 3GP usually carries, so the audio is transcoded during conversion. You can choose the output audio codec under Advanced Options if your target tool needs a specific one.
What is the difference between M2TS and MTS?
They are the same BDAV transport stream with different extensions: camcorders write .mts to their memory cards, while the same files appear as .m2ts once imported via AVCHD software or onto a Blu-ray. If your tool specifically wants the camcorder-style extension, use 3GP to MTS instead.
Does M2TS playback work in regular media players?
Not everywhere. VLC, MPC-HC, and most desktop HD players open .m2ts directly, but many phones, browsers, and lightweight players do not. If broad playback matters more than authoring compatibility, MP4 is the safer container.
Are my uploaded files kept private?
Yes. In our testing a short phone clip uploads in a second or two; files travel over an encrypted connection, are processed on our servers, and are deleted automatically after a few hours. There is no sign-up, no watermark, and files are never shared or made public.
