Audiogram Maker

Turn a podcast or voice clip into a shareable video with a moving waveform, cover art and a title.

Free, no uploads, no sign-up. Runs 100% in your browser.

How Audiogram Maker works

Everything is drawn or encoded on your device, so drafts stay private until you post them. The background is drawn on a canvas and FFmpeg (WebAssembly) renders the waveform and encodes H.264 video with AAC sound.

Input: MP3, WAV, M4A, OGG, FLAC. Output: MP4.

How to use Audiogram Maker

1. Drop an audio file.
2. Add a title, subtitle and optional cover art.
3. Pick the size, waveform style and the part of the audio.
4. Press Make audiogram and download the MP4.

Tips

• Video tools encode on your device, so short clips finish much faster.
• Square and 4:5 sizes take the most space in feeds. 9:16 is for stories, reels and shorts.

Audiogram Maker FAQ

Are my files uploaded?

No. This tool runs entirely in your browser tab. Files are read from your disk into memory and the result is generated locally.

Is it free? Are there limits or watermarks?

Free and open source (MIT). There are no file-size caps, daily quotas, accounts or watermarks.

Does it work offline?

Yes, once the page (and any engine it needs) has loaded, it keeps working without a connection thanks to the service worker cache.
