Turn uncompressed WAV recordings into compact MP3 files that play everywhere and are easy to share. Everything runs right inside your browser, so your audio is not uploaded by default.
In “Local” mode your file never leaves your device. No uploads, no server – ideal for sensitive recordings.
Pick “Local” for full privacy or “Server” for very large files and every format.
No sign-up, no queue, no watermark. Choose a file, convert, download.
MP3 is a lossy format, so a little detail is discarded during conversion. At bitrates of 256 kbps and above, most listeners won't notice any difference.
A WAV file usually shrinks to roughly a tenth of its size, depending on the bitrate you pick. That makes MP3 perfect for email and messaging apps.
No. Conversion happens locally in your browser by default. An optional server mode exists for very large files, but you have to choose it explicitly.
Yes. You can pick a bitrate from 128 up to 320 kbps and decide for yourself whether smaller files or higher quality matters more to you.
