Frequently Asked Questions

What does brightness adjustment do?

Brightness makes your image lighter (positive values) or darker (negative values) overall.

How does contrast affect my photo?

Contrast increases the difference between light and dark areas, making images more vivid and dramatic.

What is saturation in photo editing?

Saturation controls color intensity - higher values make colors more vibrant, lower values create muted or black-and-white effects.

Can I undo adjustments?

Yes, just click "Change Image" to reset and start over with the original photo.

Will editing reduce image quality?

Our editor preserves original resolution and minimizes quality loss during processing.

What's the best way to enhance dark photos?

Increase brightness (+30 to +50), add some contrast (+10 to +20), and adjust saturation as needed.
