💡 Combine an audio track with a still image to make a simple MP4 — the standard way to put a song, mix, or podcast episode on a video platform. Files stay in your browser; nothing is uploaded. (Keep total size under ~2 GB on this device.)

ມັນເຮັດວຽກແນວໃດ

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
FFmpeg.wasm loads once
The WebAssembly build downloads on first use and is cached afterwards.
2
You add an audio file and a cover image
Both are read locally — never uploaded.
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
You download the MP4
The result is ready to upload to YouTube, Instagram, or anywhere that needs video.
