Why convert WAV to MP3?
WAV is uncompressed, so files are huge — often around ten times the size of an MP3. Converting to MP3 makes recordings, samples and voiceovers small enough to email, upload or store, with barely any audible difference at a good bitrate.
Frequently asked questions
Why are WAV files so large?
WAV stores raw, uncompressed audio, so even a few minutes can run to tens of megabytes. MP3 compresses that dramatically.
How much smaller will the MP3 be?
Typically around a tenth of the WAV size, depending on length — while staying clear and clean at our high-quality VBR setting.
Is any quality lost?
MP3 is lossy, so there's a small change, but at our quality setting it's inaudible for most music and speech.
Can I convert several at once?
Yes — add up to 25 WAV files and download them together as a ZIP.
