How to convert part to mp4 file

Converting Partially Downloaded Files directly to MPEG-4 Videos (.part to .mp4 conversion) is not possible.

You can try renaming the file's suffix from PART to MP4, and see whether the file is playable via any media player. In most cases, however, the file will be corrupted.

Your only option is to download the file again. Ideally, the system will allow you to resume downloading the already partially downloaded PART file.

Simply put, it is impossible to convert PART to MP4 directly.
Thus, there is no so-called part to mp4 converter or a free online .part to .mp4 converter to be found.
