Questions
Does converting MP3 to WAV improve the sound?
No. The WAV will sound the same as the MP3, because the detail removed by MP3 cannot be recovered. The file is much larger, but it is easier for editors to work with.
Is MP3 to WAV free?
Yes. You can convert one file at a time, up to 50 MB, for free with no sign-up. Paid plans convert up to 20 files at once and handle files up to 300 MB.
Are my files uploaded?
No. The conversion runs inside your browser, so your file never leaves your device. The converter itself downloads once (about 30 MB) and your browser keeps it for next time.
Do I need to install anything?
No. Haikit works in the browser on Windows, Mac, Linux, iPhone and Android. There is nothing to download or install.
