Why convert WAV to MP3?
MP3 uses lossy compression, so expect a noticeably smaller file than the uncompressed WAV original, at some cost to quality. The main reason to convert WAV to MP3 is compatibility: MP3 plays on virtually any device or app without an extra codec, while WAV doesn't always. If you're sharing a file with someone else, sending it to a tool that expects a specific format, or archiving it for the long term, MP3 is usually the safer target.

Frequently asked questions
Is converting WAV to MP3 free?
Yes — the first 50 conversions every month are free on any plan, including WAV to MP3.
Will I lose quality converting WAV to MP3?
MP3 is universally supported lossy audio format. We use the highest-quality encoder settings by default so visual or data loss is minimized.
Do you keep a copy of my file?
No, not by default. You choose a retention window at upload — immediate, 1 hour, 24 hours or 7 days — and the file is permanently deleted after that.
What is WAV?
Uncompressed PCM audio, the studio standard.
What happens if a conversion fails?
You get a clear error message and the job is marked failed in your history — we never silently drop a file. Retry is one click, and nothing is charged against your quota for a failed job.
