Professional Threshold Tool for Everyone
The Threshold tool is essential for technical image prep and artistic binarization. It converts any image into a high-contrast 'binary' output (pure black and pure white). By adjusting the threshold value, you control exactly which brightness levels become black and which become white. This is perfect for cleaning up scanned documents, preparing stencils for CNC/Laser cutters, or creating bold graphic art.
