FAQ

  • Q: Does the conversion process consume my mobile data? A: Since NekoLabTools uses browser-local transcoding technology, apart from the initial page loading, the conversion process does not consume upload data. File processing runs completely offline.
  • Q: Why does the page occasionally lag when converting large files? A: Audio conversion is a computationally intensive task. Converting very long WAV recordings can consume significant CPU resources. We recommend operating in a desktop browser for a smoother experience.
  • Q: Can it extract audio from videos and convert it to MP3? A: This tool supports various audio and video container formats. If you import a video file containing an audio stream, it can also extract and convert it to MP3 format.
