Benefits of converting MOV to MKV
Get support for multiple audio/subtitle tracks and near-lossless quality
Switching from MOV to MKV means your file now offers support for multiple audio/subtitle tracks and near-lossless quality, ideal for archiving.
Wider compatibility
MOV is great for high-quality editing workflows on Apple/Final Cut Pro pipelines, but not every app or device handles it well. Converting to MKV sidesteps that, so the file opens wherever you need it to.
No quality compromise
ConvertFastHub runs FFmpeg at production settings, preserving as much of the original MOV fidelity as the MKV format allows.
Keep your original too
Converting doesn't touch your source file — you get a brand-new MKV file back and can keep both versions.
