Tips
- All processing happens locally in your browser — images are never uploaded.
- PNG preserves transparency; JPG produces smaller files with adjustable quality.
- Very large images may be auto‑downscaled to avoid browser memory limits.
- For strict black/white (no grays), apply thresholding in a future update.
