Questions
How do I get the audio from an MP4 video?
Add the MP4 file, keep MP3 selected and click Convert. Haikit saves only the sound as an MP3 file. The same works for MOV, MKV, WebM and other common video files.
Is MP4 to MP3 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.
