Heads up before converting to MKV
What this specific conversion changes about your video.
Lossless when the codecs already fit
If your MOV uses codecs MKV accepts, we remux (rewrap) it losslessly and instantly. A codec change re-encodes, which recompresses slightly.
Best practices for MKV
Small choices that keep your output sounding right.
- Play the MKV result back before deleting your original MOV.
- Pick a preset (Web, Mobile, High quality) to balance size and quality for your MKV.
