Audiogram maker — turn audio into a waveform video
Drop in a podcast clip or song and get back an MP4 with a real waveform, colors, background and captions of your choosing — rendered locally in your browser, so the audio never leaves your device.
How it works
- Drop an MP3, WAV, M4A or OGG file. It stays on your device.
- Choose a style, colors, background and caption, and preview it.
- Render and download an MP4 — ready for Instagram, TikTok or YouTube.
Frequently asked questions
Is my audio uploaded to a server?
No. The audio is decoded and the video is rendered and encoded entirely in your browser using WebCodecs — it never leaves your device.
Is the waveform a real picture of my audio?
Yes. Every bar or line is drawn from the actual decoded amplitude of your file, the same way the audio trimmer's waveform works — never a generic animation.
What video format do I get, and will it work on social platforms?
An MP4 with H.264 video and AAC audio — the format Instagram, TikTok, YouTube and X all accept directly.
Can I add my own background image, colors and captions?
Yes. Pick bar or line style, mirror it, set the waveform and background colors, swap in a background image, and add a title and caption — all previewed before you render.
Which aspect ratios are supported?
Square (1:1) for feeds, vertical (9:16) for Reels, TikTok and Shorts, and widescreen (16:9) for YouTube.
