Disadvantages of Online YouTube to FLAC Converter

  • Can't directly convert YouTube video to FLAC format
  • Unable to make conversions in batch
  • The Converting speed would be slow if you are going to convert large files
  • The potential risk of losing the quality of the FLAC audios

Extended Knowledge: FLAC VS MP3

FLAC (Free Lossless Audio Codec) and MP3 (MPEG Audio Layer-3) both work as a popular audio format to play music on different devices. But they are different in 4 ways:

  1. FLAC uses lossless compression to keep all the audio information of the original file, nothing is sacrificed; while MP3 uses lossy compression to shave off some parts of the music to make it smaller;
  2. FLAC is relatively large in size since it needs to store all the information as the original, while MP3 is smaller in size;
  3. FLAC is a perfect format for CDs, to contain all the details for a professional and pleasant music playing, while MP3 is a standard format to be played on all kinds of players;
  4. Virtually all media players support MP3 file, but not all of them can support playing FLAC files;

So, it is hard to tell if FLAC is better than MP3, it depends on what’s your priority and which device you are using to play the audios.

Does YouTube support lossless audio? What is the highest audio quality on YouTube?

The short answer is No. When you upload video to YouTube, it will automatically compress the audio, and quality will reduced during the peocess. often they will compress the audio to 192kbps. in other words, lossy. If you convert the lossy YouTube audio to FLAC, the audio quality will not be improved. and converting to FLAC is not worthy, it will just get a larger size file with the same lossy quality.

As for the highest YouTube audio quality, AAC is the default audio format for streaming services like YouTube. The best quality will come it you save the video as AAC.

Conclusion

Although free YouTube to FLAC converters can bring some conveniences to us, its limitation can’t be erased. To solve the issue once and for all, you’d better use a professional software- Cisdem Video Converter for Mac. With this all-in-one Mac YouTube to FLAC converter, everything will get brighter and easier. and it is the only app that also supports downloading YouTube videos in it's origianl format and quality.
