Frequently asked questions

Why convert MKV to MP4 instead of just renaming the file?

MKV and MP4 are different container formats with different internal structures, so simply renaming a file's extension doesn't work. Most players and phones will fail to open it. A real conversion re-packages (and often re-encodes) the video so it plays correctly as MP4.

Does converting reduce video quality?

The conversion aims to preserve the original video's resolution and quality as closely as possible, though some re-encoding is involved to fit the MP4 container's requirements. For most everyday videos, the difference isn't noticeable.

How long does conversion take?

Short clips typically finish in under a minute. Larger files, higher resolutions, or longer runtimes take proportionally longer, since video conversion is more processing-intensive than simple file operations.
