Add audio to start.

How it works

Step 1
Add the audio
MP3, WAV or M4A, up to 250 MB and 10 minutes.
Step 2
Add an image and pick a style
A cover or photo with a waveform over it, the image alone, or just the waveform with no image at all.
Step 3
Choose a shape and download
9:16 for Reels and Shorts, 1:1 for feeds, 16:9 for YouTube. The video is made on your device.

Which style for which post

Style	Looks like	Good for
Image and waveform	Your image with a moving waveform near the bottom	Podcast clips and song previews
Image only	A still image for the length of the audio	Full episodes and uploads where motion is not needed
Waveform only	A white waveform on black	Quick audiograms with no artwork

Want a person speaking instead of a waveform?

A waveform shows sound; a face speaking holds attention differently. Audio driven lip sync animates a photo of the host to the same audio file, which is a different tool: see the call to action below.

Use it from an AI assistant or a script

Every setting is a URL parameter, so an assistant can send a link with the options already chosen. The tool still runs on the person's own device.

Parameter	Values	Default	Meaning
`style`	`both, image, wave`	`both`	Picture
`shape`	`9:16, 1:1, 16:9`	`9:16`	Shape

Frequently asked questions

Everything you need to know before you start.

Add the audio file, optionally an image, choose image and waveform, image only or waveform only, pick a shape, and download the MP4. It runs in your browser with no upload.

Yes. Choose Waveform only and the video shows a moving white waveform on black for the length of the audio.

Choose 9:16 for Reels, Shorts and TikTok, 1:1 for square feed posts, and 16:9 for YouTube. The tool outputs 720 by 1280, 720 by 720 or 1280 by 720.

Image only videos are quick. Waveforms are drawn frame by frame, so a few minutes of audio can take a few minutes in the browser; keep the tab open.

No. It is processed on your device with FFmpeg running in WebAssembly.
