Background image
A cover, photo or poster: PNG, JPG or WebP. Without an image, the background is the colour from the settings. You can also drop it onto the page together with the audio.
Turn a podcast clip, a song or a voice message into a video for Instagram, TikTok, YouTube Shorts or X: the sound plays over your cover or a solid colour, with an animated waveform or spectrum. Square 1:1, vertical 9:16 or horizontal 16:9 — the audio is never uploaded.
How it works
- Choose an audio file — MP3, M4A, WAV, OGG, FLAC, Opus or AAC — and, if you like, a background image; you can drop both at once.
- Pick the format, a waveform, a spectrum or no visualization, its colour and the background colour.
- Click “Make video” and download the MP4 (H.264 + AAC), ready to post.
Frequently asked questions
What happens if the image does not match the format?
The image is shown whole, without cropping, and the empty space around it is filled with a blurred, darker copy of the same image — the way vertical videos are made from landscape photos.
How long can the audio be?
Up to 10 minutes: the video is encoded right in your browser at 720p and 25 frames per second, and longer files would take too long. For a social post, cut the best fragment with the “Trim audio/video” tool first.
Is it free?
Yes. All tools are free, with no sign-up and no watermarks.
Are my files uploaded to a server?
No. Everything runs in your browser, so your files never leave your device.
