WAV, AIFF, AU, RAW, and PCM files can store uncompressed audio data. RAW files contain only the audio data, without even a header on the file. A compressed sound file sacrifices some loss in quality (hence the term “lossy”) as a tradeoff for a smaller footprint or file size. A 20MB wave file can be converted to MP3 format, resulting in a file that’s just a few megabytes in size. Other lossy formats include Ogg Vorbis (.ogg), Advanced Audio Coding (.acc) or MP4 (.mp4), and Windows® Media Audio (.wma). ACC/MP4 files are slightly smaller in size than MP3s with an encoding scheme that purportedly results in higher quality sound than MP3s.

JPG, on the other hand, is a lossy compressed file format. “Lossy” means that there’s a loss of quality from the original, uncompressed image. That said, JPG files can be compressed far more than a PNG. This makes them popular for web use, since they’re fast to download and don’t take up much data.
