Download the whole Playlist #

You can download all mp3 files from a playlist in one zip file with one click on Download button. The playlist has to be publicly available. If some of the videos in it are private or unavailable, they will be skipped.

Time required to download a playlist is the same as the time required to download each mp3 from it successively.

Auto select Bitrate #

By default, YTBmp3 will choose the best audio source from YouTube to do the conversion and calculate the highest possible mp3 bitrate. Just leave the Auto bitrate selected bellow the Download button.

Usually, mp3 audio bitrate for YouTube videos is 160kbps.

Select a custom Bitrate #

If you prefer to convert mp3 with a specific bitrate, just select one, in the list below the Download button instead the Auto bitrate option. There is a wide range of options from 64kbps to 320kbps.

Be aware that the higher bitrate then the one available from YouTube will not result the more quality sound.

Trim the Length of audio #

More options… reveals a set of new fields and the two of them, labeled Trim, allow length trimming. The first input box is for start time and the second is for end time. While watching YouTube video, make note which part you want to convert and enter the start and end times before starting the download.

Time can be represented:

  • in seconds (10.5, 1, 0.33)
  • with colon separating hours, minutes and seconds (1:35.2, 16:4, 4:0)
  • with h, m and s suffixes (1h20m1.8s, 3m1s, 1m, 45.4s)

As you can see from the examples, a subsecond precision is possible, if that is important for you.

Change the audio reproduction speed #

The second option in More options… is the Tempo. It allows you to change the audio reproduction speed, just as YouTube allows to change the playback speed. If your player does not have such feature, you can download an mp3 which is already set to a desired reproduction speed.

This option is also available for playlist download to apply the same tempo for all files.

Podcast and presentation listeners will benefit very much as the popularity of YouTube Speed setting is very high for such videos.
