Audio & video
Audio to Video
One image + one audio file = an MP4 ready to publish.
The image stays still for the full duration of the audio.
YouTube won't take a bare audio file — but it will happily take this. Drop in your MP3, WAV or any recording, add a still image (cover art, logo, episode artwork), and the tool builds a 1280×720 MP4 right in your browser, with a progress bar so you know exactly where it's at. Your files are never uploaded to a server, and the audio track comes through untouched. It's the fastest way to get a podcast episode, interview, demo track or guided meditation onto YouTube and other video-only platforms. Free, with no account, no watermark and no length limit beyond what your device can handle.
How does it work?
- Drop your audio file (MP3, WAV…).
- Add the image to use as the backdrop (cover art, logo, artwork).
- Click "Create video" and watch the progress.
- Download the MP4 — ready for YouTube and social platforms.
Frequently asked questions
What image works best?
A 16:9 image of at least 1280×720 pixels gives the cleanest result. Square cover art works too — it's fitted neatly inside the video frame.
Is the audio quality preserved?
Yes. The audio is encoded to AAC at a high bitrate with no trimming or processing — the difference from the original is inaudible in virtually all cases.
How long does the conversion take?
Because the image is static, rendering is fast: usually under a minute for a full podcast episode on a recent computer, depending on audio length and your hardware.
Can I upload the result to YouTube?
Absolutely — the output is an H.264/AAC MP4 at 1280×720, the format YouTube recommends, and it's accepted by most other platforms and social networks too.
