Frequently asked questions
Is this WAV to MP3 converter free?
Yes — completely free, with no signup and no watermark. Convert as many files as you like.
Does my file get uploaded to a server?
No. The conversion runs entirely in your browser using WebAssembly, so your WAV file never leaves your device — good for private or sensitive recordings.
Why convert WAV to MP3?
WAV is uncompressed and large; MP3 is compressed and far smaller (often 10× less), which makes it easier to store, email, and upload while sounding nearly identical.
Will I lose audio quality?
MP3 is a lossy format, so there's a small reduction, but at standard bitrates it's hard to hear. Keep the WAV for archival masters; use MP3 for sharing.
What's the largest file I can convert?
Up to 200 MB. Because it runs in your browser, very large files depend on your device's memory — shorter files convert fastest.
