Occasionally, the VLC Media Player will generate an error message stating that the .undf multimedia format is not supported. This prompts some users to attempt converting their media files to other format, despite them being absolutely fine. Such error is displayed if the VLC Media Player doesn't have a suitable decoder installed for the video format.
Videos in the .mkv format can occasionally trigger such error messages. No need for a conversion in that case. All you need to do is to look for a newer VLC Media Player version, or its codecs. This issue can occasionally be caused by partially downloaded files; in such case, you should either complete the download process or download the file again.
The .undf file type is not recognized by any file conversion tool.
Simply put, it is impossible to convert UNDF to MKV directly.
Thus, there is no so-called undf to mkv converter or a free online .undf to .mkv conversion tool.

Understanding UNDF and MKV file formats
The UNDF file format is not a specific file type but rather an error message indicating that a media player cannot recognize or decode the file format. This often occurs when the necessary codecs are missing or the file is incomplete. On the other hand, the MKV (Matroska Video) file format is a popular multimedia container format known for its ability to hold an unlimited number of video, audio, picture, or subtitle tracks in one file. MKV is widely used for high-quality video content and is compatible with many media players.
Converting UNDF to MKV
Since UNDF is not a specific format, converting it directly to MKV involves identifying the actual file format and ensuring the correct codecs are installed. Once the file is playable, it can be converted to MKV using a reliable converter.
Best software for converting UNDF to MKV
One of the best software options for converting media files to MKV is VLC Media Player. VLC is a versatile media player that can also convert files. To convert a file using VLC, follow these steps:
- Open VLC Media Player.
- Go to Media → Convert/Save.

- Click Convert/Save at the bottom.
- In the Profile dropdown, select Video - H.264 + MP3 (MP4) or a similar profile that supports MKV.
