Podcasts and music
Musicians post singles and podcasters post episodes this way every day. The video uses a frame rate of 2 frames per second, which is enough for a still image and keeps the file small.
Good to know
The video uses H.264 at 2 frames per second, which is all a still picture needs, with AAC audio at 192 kbps. The result is barely larger than the audio file and plays on every platform. The video ends exactly when the audio ends.
Frequently asked questions
Can I add a waveform animation?
Not yet. This tool makes a still-image video.
Is the Audio to Video Converter free?
Yes, completely free, with no sign-up and no watermark. Files up to 1 GB each can be converted, and there is no daily limit.
Is my file uploaded to a server?
No. The converter runs inside your browser using WebAssembly, so your file is processed on your own device and never sent to us or anyone else.
Does it work on iPhone and Android?
Yes, in Safari, Chrome and other modern mobile browsers. Short files work best on phones; for long or high-resolution videos a computer is faster.
