FAQ

common questions

Is the WAV to MP3 converter free?

Yes. Every conversion on this site is free, with no signup, watermark or file count limit.

Are my files uploaded to a server?

No. Conversion runs entirely in your browser using ffmpeg.wasm / lamejs. Your files never leave your device, so we cannot see them even if we wanted to.

Is there a file size limit for WAV to MP3?

Files up to about 500 MB work reliably. Larger files may run out of memory depending on your device.

Does it work offline?

Once this page has loaded, yes. You can disconnect from the internet and the converter will still work. Reloading the page does require connectivity.

Will my WAV file lose quality when converted to MP3?

It depends on the formats involved. Converting between lossy formats (JPG, MP3) re-encodes data and slightly reduces quality. Lossless formats (PNG, WAV, FLAC) preserve everything. Pixel dimensions and color depth are preserved for image conversions.
