What does increasing contrast do to an image?

Increasing contrast stretches the tonal range so dark areas become darker and light areas become lighter. This makes the image look more vivid and dramatic. Decreasing contrast compresses the range, creating a softer, flatter appearance.

Can contrast adjustments reveal hidden details?

Yes. In flat or hazy images, increasing contrast can reveal texture and detail that was hard to see. However, very high contrast may clip shadow or highlight details irreversibly.

Is my image processed locally?

Yes. All contrast adjustments happen inside your browser. Your image is never uploaded to a server, so your files remain completely private.
