Questions
Can I download videos from YouTube, TikTok or Instagram here?
No. Those sites do not allow it in their terms, so Kitwise only works with files that are already on your device, such as your own recordings.
Why does converting a video take as long as the video?
The browser records the clip while it plays, so a one-minute clip takes about a minute. MP3 and WAV are made in seconds.
Can I make a WhatsApp or Instagram clip?
Yes: trim the video, then compress it if needed.
