Convert MTS Files to HEVC on Your Device
Make a HEVC copy of MTS in your browser for modern high-efficiency delivery. On-device processing keeps the original media local from selection to download.
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.

Preview (optional)
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 modern high-efficiency delivery
- Supply HEVC when an editor, player, or delivery form will not accept MTS
- Create a HEVC copy from MTS for HEVC-capable hardware and modern services
Workflow
- Choose a MTS file from your device
- Set the download name for the new HEVC
- Create the HEVC version
- Open the downloaded HEVC in its intended workflow
Processing notes
- Processing demand varies with the codecs found in the source during this MTS-to-HEVC job.
- Long MTS files consume more memory and take longer to decode.
- Confirm the HEVC output meets the receiving system’s technical limits.
Compatibility notes
- HEVC serves HEVC-capable hardware and modern services, whereas MTS commonly serves AVCHD cameras, editors, and archives.
- For MTS-to-HEVC delivery, plan for platform and licensing-dependent playback.
- After leaving MTS, the receiving app must support the streams encoded inside HEVC, not only its extension.
Troubleshooting
- MTS to HEVC taking too long? Close other demanding apps, then test a short sample before the full file.
- HEVC converted from MTS not opening? Test a compatible player and inspect the output streams.
- Inspect the generated streams when an app recognizes HEVC but refuses playback.
MTS to HEVC converter FAQ
When does MTS to HEVC conversion make sense?
It is useful when MTS media created for camera-media workflows must enter a HEVC system designed for modern high-efficiency delivery.
Where is the MTS source processed?
The browser prepares HEVC from MTS on this device instead of sending the source to a remote conversion server.
How can I approve HEVC converted from MTS?
Test the HEVC file in the receiving app and compare duration, picture, sound and timing with the MTS source.
