Is this a video or an animated waveform?

No. The output is a static PNG image — a still you can place in a promo graphic, an episode page, or a social post. It does not move and there is no video file.

Which audio formats can I upload?

MP3, M4A, WAV, AAC, FLAC, OGG, OPUS, and WMA, up to 500 MB each. You can mix formats in one batch and every file comes back as its own PNG.

No. No AI model touches your audio — the waveform is rendered deterministically from the audio samples, so the same file and theme always produce the same image.

How is pricing calculated?

1 credit per image, with a 2-credit minimum per job. Rendering one file is 2 credits; rendering ten files is 10 credits.

Yes. Rendering runs on our own servers, your files are never sent to a third party or used to train a model, and everything is auto-deleted 7 days after the job finishes.

How it works

1Upload your audioDrop in any mix of MP3, M4A, WAV, AAC, FLAC, OGG, OPUS, and WMA files — one clip or a whole season — and pick a dark or light theme.

2Each waveform is renderedEvery file is decoded and its full waveform drawn into a 1200×300 PNG on the background you picked. No AI model touches your audio — the rendering is fully deterministic.

3Download the imagesOne PNG per upload, named after the original — episode-12.mp3 → episode-12-waveform.png. A single file downloads on its own; a batch comes back as one zip.

Who uses this tool

PODCASTING

Promo stills for every episode

Render a waveform of each episode and layer it under the title in your promo template — the whole season in one batch.

SOCIAL MEDIA

Audiogram-style stills

A waveform PNG gives an audio quote post something to look at — drop it behind the pull quote as a static audiogram frame.

MUSIC & AUDIO

Track art for releases and demos

Turn a mix or demo into a waveform image for the Bandcamp page, the private link, or the cover of a works-in-progress folder.

VOICE & NARRATION

Portfolio embeds that show the work

Voice actors and narrators can pair each demo reel with its waveform so the portfolio page shows the audio, not just a list of links.

MARKETING

Landing pages with audio sections

A waveform image marks the audio block on a landing page without embedding a heavyweight player above the fold.

EDUCATION

Course pages for audio lessons

Give each recorded lesson a waveform thumbnail so students can tell the long lectures from the short recaps at a glance.

SECURITY

Built for sensitive documents

Bank statements, medical files, case records. Security isn't a feature we added — it's the foundation.

Questions

One 1200×300 PNG per uploaded file, showing the full waveform of the recording drawn edge to edge on a dark or light background. Each image is named after its original file — episode-12.mp3 becomes episode-12-waveform.png.
