Original's Smart Pixel Cleanup

Smart Pixel Cleanup finds stray/ accidental pixels you didn't mean to leave behind in your pixel art and animations, let's you review each one before deleting them and once you are sure you may delete each one individually!

How it works:
Run a scan, and the tool walks through your sprite looking for pixels that don't fit, fully isolated dots with no neighbors, or tiny disconnected specks of just 1–3 pixels. Each one gets a suspicion score from 0–100, and results are ranked so the most obvious mistakes show up first.

The threshold slider:

controls how strict the scan is:

• High (80–100)  only flags the most obvious garbage: fully isolated single pixels. Very few false positives, good for a quick first pass.
• Default (60)  catches isolated pixels and small 2–3px clusters. A good balance for most cleanup passes.
• Low (0–30)  flags almost anything with limited neighbors, including small intentional details. Useful if you want a thorough sweep and don't mind reviewing a few false positives.
