How to Adjust Image Contrast
Refine tonal separation in three steps:
Step 2
Adjust the Contrast Slider
Open Finetune and select Contrast. Move the slider right for stronger light-dark separation or left for a flatter appearance.
Step 3
Review and Save
Check highlight and shadow detail in the preview, then click 'Save' to download the result as PNG.
Add Definition to Flat Images
Increase contrast when highlights and shadows look too similar. A moderate adjustment can give shapes and tones more separation without changing the image dimensions.
Soften Harsh Highlights and Shadows
Reduce contrast for a gentler tonal transition or a deliberately faded look. Avoid extreme settings that hide detail in the darkest and brightest areas.
Focused Image Editing Controls
Open the control you need, preview the change, and save the result without navigating a complex desktop editor.
Crop, Resize, Rotate, and Adjust
Use focused tools for dimensions, orientation, tone, color, annotations, text, frames, and selective blur.
