Audio to Video
Combine an audio file with a static image to create a video file (MP4/WebM) entirely in this tab. Your files never leave your device.

How this works
This tool uses ffmpeg.wasm, a WebAssembly port of FFmpeg, to run the command -i audio_input -i image_output -c:v libx264 -pix_fmt yuv420p -r 30 -shortest output.mp4 (for MP4) or similar for WebM directly in your browser. The audio and image are loaded into memory, processed, and the resulting video is offered as a download. Nothing is uploaded to a server.
Common uses
Turning podcasts or audio clips into videos for YouTube, Instagram, or other platforms that require video; creating simple music visualizers with a static image; sharing audio lectures on video platforms.
