Should You Choose Lossless Or Lossy?

The first step in reducing the size of audio files is to determine if your audio is “lossless” or “lossy”.

  • Lossless formats have all the original data intact and therefore are much larger files.
  • Lossy formats use a lower bit rate, removing much of the data from an audio file. This reduces the overall sound quality but also makes it a much smaller and therefore easier file on your hard drive.

Lossy formats are suitable in most situations. As long as you don’t set the bit rate too low, it is unlikely that you will be able to tell the difference between lossy and lossy audio, especially if you are listening on your phone through headphones.

That said, if storage space isn’t an issue and you have high-quality speakers or headphones, a lossless format might be the way to go.

Lossless formats also allow you to “perpetuate” your audio, should you ever acquire better listening equipment. You can still convert lossless audio to a lossy format, but you cannot convert lossy audio back to higher quality lossless formats.
