This is the portable version of 4K YouTube to MP3, a straightforward piece of software that downloads clips from YouTube, extracts the audio content and saves it to MP3 format, as the name implies.

The application includes a standard configuration set, suitable for all types of users, even the ones with little or no experience in conversion software.

Since installation is not a prerequisite, you can drop the program files to a custom location on the hard disk and just click the executable to run.

It is also possible to save 4K YouTube to MP3 to a USB flash disk or similar storage unit, in order to run it on any machine with minimum effort and without prior installers.

An important aspect to take into account is that the Windows registry does not get updated with new entries, and no extra files are created on the HDD without the user's consent.

The interface is based on a regular window with a minimalistic layout, where you can paste a YouTube URL right in the main frame, in order for the downloading and conversion procedure to automatically start. The list shows the title, downloading speed and estimated time remaining for each item.

It is possible to download individual clips or entire playlists. There is no limit to the number of downloading tasks, so you can add as many videos as you want.

As far as program preferences are concerned, you can select the output format between MP3, M4A and OGG, adjust the quality (low, medium, high), alter the default saving directory, as well as ask 4K YouTube to MP3 to add numeration to file names in playlists and to insert the resulting tracks into the iTunes library automatically.

4K YouTube to MP3 has a very good response time and uses pretty low CPU and RAM, so it does not affect the overall performance of the computer or interrupt normal user activity, since it can be minimized to the taskbar.

The tool delivers quality audio tracks. Unfortunately, it frequently stops midway downloading tasks and does not resume the job. Nevertheless, 4K YouTube to MP3 contains a comfortable interface and intuitive options for any user who wants to download YouTube clips and create MP3 tracks seamlessly.
