Convert MTS Files to H.265 on Your Device
Convert MTS 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 camera-media workflows to a workflow built for efficient modern encoding
- Supply H.265 when an editor, player, or delivery form will not accept MTS
- Create a H.265 copy from MTS for newer devices and storage-conscious delivery
Workflow
- Open the MTS source in the converter
- Set the download name for the new H.265
- Create the H.265 version
- Save the H.265 result and inspect playback
Processing notes
- Processing demand varies with the codecs found in the source during this MTS-to-H.265 job.
- Long MTS files consume more memory and take longer to decode.
- Compare the H.265 duration with the source before publishing.
Compatibility notes
- H.265 serves newer devices and storage-conscious delivery, whereas MTS commonly serves AVCHD cameras, editors, and archives.
- For MTS-to-H.265 delivery, plan for slow decoding on older hardware.
- After leaving MTS, the receiving app must support the streams encoded inside H.265, not only its extension.
Troubleshooting
- MTS to H.265 taking too long? Close other demanding apps, then test a short sample before the full file.
- H.265 converted from MTS not opening? Test a compatible player and inspect the output streams.
- A H.265 extension alone may not be enough; verify the required internal codec.
MTS to H.265 converter FAQ
When does MTS to H.265 conversion make sense?
It is useful when MTS media created for camera-media workflows must enter a H.265 system designed for efficient modern encoding.
Where is the MTS source processed?
The browser prepares H.265 from MTS on this device instead of sending the source to a remote conversion server.
How can I approve H.265 converted from MTS?
Test the H.265 file in the receiving app and compare duration, picture, sound and timing with the MTS source.
