Frequently asked questions
Is this WAV to MP3 converter free?
Yes — completely free, no account, no watermark. The only limit is your device's memory, since everything runs locally.
Are my files uploaded to a server?
No. Your WAV file is processed entirely in your browser using WebAssembly. It never leaves your device.
Will the quality change?
MP3 is compressed, so you can choose a bitrate (192k is a good balance). Higher bitrate means better quality and larger files.
Can I convert large files?
Yes, but very large media uses a lot of memory. For big files, a desktop browser works best.
