How to make a waveform image
- Choose an audio file (or a video: its sound is used).
- Pick the style, size and colors; the preview updates as you go.
- Download a PNG, or an SVG that stays sharp at any size.
Styles
- Bars: the familiar podcast-player look, with adjustable bar width, spacing and rounded ends.
- Wave: a filled, mirrored shape of the sound.
- Line: a single line following the peaks.
Good to know
- The whole file is drawn, from start to end. To show a part, cut it first with the Audio Trimmer.
- "Fill the height" scales the loudest moment to the top, so quiet recordings still make a full picture.
- A transparent background lets you place the waveform on any design.

よくある質問
Can I use the image commercially?
The picture is made from your own file on your device, so it is yours to use like the sound it comes from.
Is my audio uploaded?
No. The sound is read in your browser and never sent anywhere.
