Optimize for your platform
यो कसरी काम गर्छ
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.
- 1FFmpeg.wasm loads onceThe WebAssembly build downloads on first use and is cached afterwards.
- 2You add an audio file and a cover imageBoth are read locally — never uploaded.
- 3FFmpeg renders the videoThe 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.
- 4You download the MP4The 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.
