Frequently Asked Questions
Q: What's the difference between grayscale and black & white?

A: Grayscale preserves shades of gray, while black & white conversion creates pure black and white pixels only. This creates a more dramatic, high-contrast effect.

Q: How does the threshold work?

A: The threshold determines the cutoff point: pixels darker than the threshold become black, pixels lighter become white. Lower values (0-127) create more black areas, higher values (128-255) create more white areas.

Q: Can I undo the conversion?

A: No, black & white conversion permanently removes color and gray tone information. We recommend keeping your original image as a backup.
