Convert M2TS Files to H.265 on Your Device
Convert M2TS to H.265 in your browser for efficient modern encoding. The source remains on your device throughout local processing.
HEVC in the browser depends on your FFmpeg.wasm build: encoding is CPU-only (no GPU encoders), can be slow, and some cores omit libx265. If HEVC is unavailable, we use H.264 or MPEG-4 in MP4 instead and show a brief notice.

When your browser supports it, your video appears here. If preview does not load, you can still convert your file normally.

No worries — your video can still be converted. Set your file name and click Convert when you are ready.
Quick use cases
- Adapt disc and camcorder workflows to a workflow built for efficient modern encoding
- Supply H.265 when an editor, player, or delivery form will not accept M2TS
- Create a H.265 copy from M2TS for newer devices and storage-conscious delivery
Workflow
- Add the M2TS media you want to process
- Set the download name for the new H.265
- Process the media into H.265
- Save the H.265 result and inspect playback
Processing notes
- The device processor performs decoding and encoding during the job during this M2TS-to-H.265 job.
- Duration, resolution, and source bitrate affect how quickly M2TS is processed.
- Check picture, sound, and timing in H.265 before removing the source.
Compatibility notes
- H.265 serves newer devices and storage-conscious delivery, whereas M2TS commonly serves Blu-ray and AVCHD editing systems.
- For M2TS-to-H.265 delivery, plan for slow decoding on older hardware.
- After leaving M2TS, the receiving app must support the streams encoded inside H.265, not only its extension.
Troubleshooting
- M2TS to H.265 taking too long? Close other demanding apps, then test a short sample before the full file.
- H.265 converted from M2TS not opening? Test a compatible player and inspect the output streams.
- Use the receiving app’s documented H.265 profile when generic playback succeeds but import fails.
M2TS to H.265 converter FAQ
When does M2TS to H.265 conversion make sense?
It is useful when M2TS media created for disc and camcorder workflows must enter a H.265 system designed for efficient modern encoding.
Where is the M2TS source processed?
The browser prepares H.265 from M2TS on this device instead of sending the source to a remote conversion server.
How can I approve H.265 converted from M2TS?
Test the H.265 file in the receiving app and compare duration, picture, sound and timing with the M2TS source.
