About the MP3 format
MP3 (MPEG-1 Audio Layer III) is the most widely supported audio format there is: every phone, car stereo, browser and player reads it. It is lossy, storing music at a fraction of the size of the original by removing detail the ear is least likely to notice. At 192 kbps or more it is transparent for most listeners.
About the WAV format
WAV (Waveform Audio) stores audio uncompressed as raw PCM samples, exactly as it was recorded or decoded. It is the standard for recording, editing and mastering because nothing is lost, and it plays everywhere. The price is size: a minute of CD-quality stereo takes about 10 MB.

Does converting MP3 to WAV lose quality?
No. WAV is a lossless format, so every sample of the decoded MP3 audio is stored exactly. The file is usually larger than the original.

Yes. Add up to 5 files of up to 200 MB each, convert them in one go and download the results one by one or as a ZIP.
