Frequently asked questions
What files can it read?
Anything your browser can decode, typically WAV, MP3 and M4A. The audio is read locally to draw the waveform.
Is my audio uploaded?
No. Decoding and rendering happen entirely in your browser and nothing is uploaded.
Can I change the size?
The PNG exports at a clean fixed resolution. Scale it in your editor to fit the layout you need.
