How to convert M2TS to MP4
Upload your M2TS file
Drag and drop a M2TS file to turn into MP4, or click to browse. Anything under 1GB, and nothing is installed.
Confirm MP4 as the output
MP4 is already selected, so there is nothing to configure. Switch to another format in the panel if M2TS needs to go somewhere else.
Convert and download

Why convert M2TS to MP4?
M2TS is the Blu-ray flavour of the same transport stream MTS uses. It carries high-bitrate H.264 with multi-channel audio, which is why a few minutes of footage can run to gigabytes.
The practical problem: Browsers, phones and social uploads do not accept M2TS. Multi-channel DTS or AC-3 audio confuses consumer editors. Bitrates are far higher than anything you would ever share online.
MP4 solves that. Plays natively on every phone, browser, TV and editing app with no extra codecs. Every upload form accepts it, from YouTube and LinkedIn to Slack and email. H.264 keeps files small enough to send while still looking sharp at 1080p.
M2TS carries Blu-ray-grade bitrates that make no sense outside a disc: gigabytes for a few minutes, with multi-channel audio nothing on a phone can decode. MP4 with H.264 and stereo AAC keeps the picture and drops the weight.

M2TS to MP4 questions
Is the M2TS to MP4 converter free?
Yes. Convert and preview the result for free, then create a free account to download it. There is no per-file charge and no watermark on the MP4 itself beyond the free-plan badge.
Do I need to install any software?
No. The conversion runs on our servers and you use it from a browser tab, so it works the same on Windows, macOS, Linux, iPhone and Android. Nothing to install at either end. Where M2TS plays: Blu-ray players and VLC. Where the MP4 you get back plays: Every phone, browser, TV and editor.
Does converting M2TS to MP4 reduce the quality?
Converting re-encodes the video, so it is not bit-for-bit identical. We encode at a high quality target, which keeps the result visually indistinguishable from the M2TS on normal viewing. What changes is the container and the codec. MP4 holds: H.264 video, AAC audio. Converting the same file back and forth repeatedly will eventually show, so keep your original.
How large a file can I convert?
Anything under 1GB per upload, which is more footage in some formats than others. M2TS: Very large. MP4 coming back: Small for the quality. For anything bigger, trim or compress it first, both are free tools here.
Is my file kept private?
Your upload is processed and then held only as long as your project needs it. Nothing is published, indexed or shared unless you create a share link yourself.
