Kif Taħdem

Video platforms like YouTube need a video file, not just audio. The standard trick is to show a single cover image for the whole track. This builds that MP4 with FFmpeg in your browser.

  1. 1
    FFmpeg.wasm loads once
    The WebAssembly build downloads on first use and is cached afterwards.
  2. 2
    You add an audio file and a cover image
    Both are read locally — never uploaded.
  3. 3
    FFmpeg renders the video
    The still image is looped for the full length of the audio (-shortest) and encoded to H.264 MP4 with the audio as an AAC track.
  4. 4
    You download the MP4
    The result is ready to upload to YouTube, Instagram, or anywhere that needs video.

Turn a song, DJ mix, or podcast episode into an uploadable video without sending your audio to a server — everything runs on your device.
