What exactly do I get back?

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.

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.

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.

Encrypted in transit

Encrypted in transit over TLS 1.2+, and stored in access-controlled, encrypted object storage. Files are protected the moment they leave your browser.

auto_delete

Deleted, not stored

Files are deleted after processing. Everything runs on our own hardware and is never sent to an outside AI service, so your data is never used to train models.
