123 Convert YouTube to MP3

123 Convert YouTube To MP3 is a simple-to-use software application that, as the name implies, lets you download YouTube clips, extract the audio stream and save it to MP3 format.
It also offers support for M4A, WMA and FLAC format. It comes packed with its own web browser for locating and downloading YouTube videos, and does not include complex options.

Ad-supported application

The installation itself does not take a long time to finish. However, since it is ad-supported, 123 Convert YouTube To MP3 is filled with third-party tools that it tries to install, so you should be careful when going through the setup steps. All offers can be declined.

Intuitive interface and options

The main application window is divided into multiple panels dedicated to navigating YouTube links, monitoring downloads and modifying app preferences.
The web browser has a search function, home button, as well as back and forward buttons. Each link is accompanied by a download button. Clicking it immediately sends the respective video to the download manager, where you can view its name, progress, speed, remaining time, and status. It is possible to download multiple clips at the same time, as well as to open the output directory without leaving the tool's interface.
As far as program preferences are concerned, you can turn the default saving location into something else, as well as pick a preferred output format. There are no other notable options available here.

Evaluation and conclusion

The app takes little time to finish download and conversion jobs, delivering quality audio tracks. However, it uses a pretty high amount of memory during this time, and it failed in its attempt to download several clips during our evaluation, although it did not indicate any errors. Unfortunately, the fact that it is filled with adware makes 123 Convert YouTube To MP3 difficult to work with.
