Why Convert M2TS to HEVC?
M2TS (MPEG-2 Transport Stream) is the Blu-ray disc container format, also used by AVCHD camcorders. These files are typically encoded with MPEG-2 or H.264 and are very large — a single Blu-ray movie can be 20–40 GB.
Converting to HEVC (H.265) reduces file size by roughly 50% compared to H.264 at the same visual quality, and even more compared to MPEG-2. This makes it practical to archive Blu-ray rips, camcorder footage, or broadcast recordings at a fraction of the original size while preserving HD/4K quality.
Audio defaults to AAC, preserving the soundtrack.

| File size (1 hr 1080p) | 5–20 GB | 1–4 GB |
| 4K/HDR support | Limited | ✅ Native |
| Device support | Blu-ray players, VLC | Modern devices (2017+) |
| Audio | AC3/DTS/PCM | AAC (default) |
Frequently Asked Questions
How much smaller will the HEVC file be?
Typically 50–80% smaller than the M2TS source, depending on whether the source uses MPEG-2 (bigger reduction) or H.264 (smaller reduction).
What CRF should I use for Blu-ray archival?
CRF 18 for visually lossless archival. CRF 23 (default) for a good balance. CRF 28 for maximum compression with some visible quality loss.
Can I batch convert?
Yes. Upload multiple M2TS files and download HEVC results individually or as a ZIP archive.
