Frequently Asked Questions
Our tool processes your WAV file entirely inside your browser using a fast audio encoding library. The file is never uploaded to any server, ensuring complete privacy and security. You simply select a WAV file, choose your desired MP3 bitrate, and click convert – the compressed MP3 file is then available for download within seconds.
Yes, it is completely free and safe. Because all conversion happens locally on your device, your audio files remain private and are never exposed to third‑party services. There are no hidden costs, ads, or file size limits beyond what your device can handle.
It depends on your needs: 128 kbps offers a good balance between quality and file size, suitable for most music and podcasts. 192–256 kbps provides higher transparency for music lovers, while 320 kbps preserves near‑lossless quality at the expense of larger files. For voice recordings, 64 kbps is usually sufficient.
The tool can handle files up to 200 MB. Since conversion happens locally, performance depends on your device's memory and CPU speed. Very large files may take a moment longer, but they will be processed without any size restrictions imposed by a server.
