Merge, concatenate, extract, convert, and play video and audio files.

 

 
Internet Download Manager (IDM) is the most popular way to download videos from the internet.
IDM Video Download Helper
is a simple and easy-to-use Windows app to merge, concatenate, extract, convert, and play video and audio files that downloaded by IDM (Internet Download Manager).
 
Merge separate video and audio files into a single file.
  If IDM downloads video and audio separately, our program can help you merge the separate video and audio files into a single file.
   
Convert M3U8 to MP4.
  If you use IDM to download HLS (M3U8), and IDM downloads a .m3u8 file and a series of .ts files, our program can help you convert them to a single MP4 file.
   
Concatenate segment files into a single file.
  If you only have segment files - a series of .ts files,  and don't have a .m3u8 file, our program can also help you concatenate these .ts files into a single file.
   
Extract audio stream from video file and save as MP3.
  If you want only audio but IDM downloads the entire video file, our program can help you extract audio stream from the video file, and save in MP3 or any other audio format.
   
Convert video/audio files between different formats.
  If your media player or device doesn't recognize downloaded video/audio files, our program can help you convert them to any format that is supported by your media player or device.
   
Play video and audio files that your media player cannot play.
  If your media player cannot play downloaded video/audio files, you can try our Universal Video Player. It supports almost all video and audio formats.
