How to use
- Upload your audio file, such as a podcast episode or music clip.
- Choose the wave color, background color, style and image size.
- Click Draw waveform to see the preview, then download the PNG.
Note: the image shows the full track from start to finish, drawn from real amplitude peaks.
Tips
- Use a strong color contrast between the wave and the background so it stands out in small thumbnails.
- Mirrored bars look best for podcast covers; the smooth line suits calm, minimal designs.
- Pick the square 1080 x 1080 size for feed posts and 1920 x 1080 for video thumbnails or banners.
