About the Image Contrast Adjuster
Contrast controls the difference between light and dark areas. Increasing it makes washed-out photos and scanned documents crisper; reducing it creates a soft, faded look. The adjustment pivots around mid-gray, the same curve the CSS contrast() filter uses.
How to use it
- Set the contrast change with the slider.
- Choose the output format.
- Drop images and download the adjusted versions.
Good to know
- Strong increases clip shadows to black and highlights to white.
- For scanned text, +30% to +60% often improves legibility.
