From URL: Paste the image link and click Load URL. If it fails, the host blocks cross-origin requests — try a different host.

2. Controls & What They Do

Posterize levels: Number of color steps — lower values create stronger, flat-color regions.
Blur passes: Smooths the image before posterizing. More passes = smoother, larger color areas.
Edge threshold: Determines how strong an edge must be to produce a black outline.
