Can I export a waveform image?

Not yet. Use a screenshot for now — the canvas renders at native resolution.

Why is the waveform a dense block?

At full-track zoom, peaks overlap into a silhouette. Zoom in to see individual cycles.

Does this upload my file?

No. Rendering is done locally with canvas and the Web Audio API.
