Frequently asked questions
+Can I convert MP3 to WAV for free?
Yes — MP3, WAV, OGG and M4A in any direction. No upload limits beyond the free file cap, no watermark in the audio.
+Is this safe for lecture recordings and interviews?
Yes. Audio is decoded and re-encoded in your browser — nothing is sent to our servers, so confidential recordings stay private.
+What bitrate should I pick?
192 kbps (Balanced) is great for music and lectures. Pro unlocks 320 kbps for highest-fidelity exports.
+Can I batch-convert a whole folder?
Drop multiple files at once. Free converts 3 in parallel; Pro queues dozens with pause/resume.
+Does it work on phones?
Yes — full mobile support in modern browsers. Files stay on the device.
