Once you've selected a YouTube video that you'd like to convert to an audio format, it's time to pick the download format and quality. Most people prefer the MP3 format since it's widely used and recognized. However, Viddly also supports downloading YouTube to AAC or Vorbis format.

Most online video downloaders only support MP3 file qualities up to 128 Kbps, but with Viddly you're able to download MP3, AAC, or Vorbis files in up to 320 Kbps quality.

Besides being much faster than online downloaders for MP3 conversion, Viddly allows you to download entire YouTube playlists in MP3 format.

Questions about YouTube to MP3 conversion

What's the best audio format for YouTube music downloads?

The quality of the sound that you hear when playing an audio file depends on several factors. An appropriate audio format is one of them. There are three major categories of audio formats;

  • Uncompressed audio: This is the original sound, as recorded directly from the source in analog form and converted to a digital signal without any modification or compression. Examples of uncompressed audio files include Waveform Audio File Format (WAV) and Audio Interchange File Format (AIFF).
  • Lossless compressed audio: This type of file is compressed using advanced algorithms that do not compromise the subjective quality of the sound. When played, you get the same acoustic experience as the source file. An example of lossless compressed audio is Free Lossless Audio Code (FLAC) which reduces the file size by about half.
  • Lossy compressed audio: These are the most common audio formats because they offer excellent audio quality while reducing the file size significantly. Some acoustic information is lost, but the difference in quality is negligible. Examples of lossy compressed audio formats include MP3, AAC, and OGG.

Viddly supports the following lossy compressed audio formats;

  • MPEG-1 Audio Layer 3 (MP3): This is by far the most commonly used audio format. The file size has been reduced by removing all acoustic information that the human ear cannot pick up. Viddly supports 128, 192, and 320 Kbps encoding, although YouTube does not yet offer streams with a bit rate higher than 165 Kbps for most videos.
  • Advanced Audio Coding (AAC): Originally designed to be the successor of the MP3 format. Even though AAC usually achieves higher sound quality than MP3 at the same bitrate, it never became as popular in comparison.
  • Vorbis: This format is commonly used in conjunction with the OGG container format and is often referred to as Ogg Vorbis. Vorbis streams can also be encapsulated in other media container formats such as Matroska and WebM. Although OGG files are more advanced in terms of sound quality and offer even higher compression ratio when compared with MP3 and AAC, many devices still don’t support the format.

So which format is best? If your audio equipment supports it, we recommend either AAC or Vorbis. However, the difference with MP3 is minimal.

How can I get my MP3 files on my phone?

You can now connect your iPhone or Android phone to your computer and transfer the MP3 file directly, or place it in a cloud storage folder such as Dropbox for wireless transfer. Now you can enjoy your favorite songs anytime and anywhere! Pretty easy, right?

Why is Viddly the best YouTube to MP3 converter?

Viddly is the #1 YouTube to MP3 converter not just because it's easy to use as compared to an online video converter, but also due to it's powerful features. It requires software installation, but the small up-front effort is definitely worth it! Here are some of the top reasons why smart users choose Viddly:

  • Viddly converts YouTube to MP3 faster than any other application or online video downloader.
  • Viddly supports more formats than most online converters, including MP3, AAC, and Vorbis.
  • Viddly allows you to download entire playlists to MP3 with a single click.
  • No more copying and pasting URLs and juggling tabs thanks to the built-in search.
  • An online YouTube to MP3 converter has to make money somehow, and they usually do this by showing obtrusive or dangerous ads or by selling your data. We make money by selling a premium version with additional features so that we don't have to resort to such tactics.
  • You can choose a custom folder for audio, video, and playlist downloads.
  • Did you previously download videos? You can also convert local files to MP3.

Why should I use a YouTube to MP3 downloader?

  • You'll be able to access your music even if you're somewhere remote without an Internet connection, such as on an airplane, or if your Internet connection were to go offline unexpectedly.
  • Streaming music requires a lot of bandwidth. By downloading your most frequently played MP3 files, you'll end up transferring a lot less data, which may lower your bills.
  • If you're a content creator then you might want to convert YouTube videos to files that can be edited and re-used under fair use provisions.

Why are online YouTube to MP3 sites so slow?

Online YouTube to MP3 converters face a major challenge, namely the fact that bandwidth costs money. If you think that anyone will spend time and money to run a server to convert YouTube video to MP3 files as a charity, then think again. The people operating such sites need to make a profit, just like any other business.

Viddly is a desktop-based product that uses your computer's processing power so that we don't face such expenses, but an online YouTube to MP3 product must generate enough profit from you using it to offset the cost of their servers. They do this by deliberately slowing down their YouTube MP3 conversion process so that you spend more time looking at advertisements. Some even resort to showing malicious ads or selling your data!

This is also the reason why an online MP3 converter will force you to copy every YouTube URL individually, rather than letting you copy a playlist video URL. They need to increase your time-on-site to increase the likelihood that you'll click on an ad. Viddly on the other hand is fully automated. You can convert a video or playlist to audio files with a single click.
