Questions
Which audio formats can Haikit convert?
It reads most common audio and video files, including MP3, WAV, M4A, AAC, OGG, FLAC, Opus, WMA, MP4, MOV, MKV and WebM, and saves as MP3, WAV, OGG, M4A, FLAC or Opus.
Can I extract audio from a video?
Yes. Add a video file such as MP4 or MOV and choose MP3 or another audio format. Haikit saves only the sound.
Why does the first conversion take longer to start?
The converter, about 30 MB, is downloaded the first time you use it. Your browser keeps it afterwards, so later conversions start straight away.
What are the free limits?
Free: one file at a time, up to 50 MB. Paid plans convert up to 20 files at once and handle files up to 300 MB.
