Brightness and contrast are the two adjustments that fix most everyday photo problems. One controls how light or dark the image is, the other controls the difference between lights and darks.
What each one does
Brightness shifts the whole image lighter or darker. Contrast stretches or compresses the gap between the dark and light areas. A flat, hazy photo usually needs more contrast, while a photo shot in dim light usually needs more brightness.
How to adjust brightness and contrast
- Open the Brightness and Contrast tool.
- Add your photo.
- Nudge brightness and contrast while watching the live preview.
- Download the improved image.

Tips for natural results
- Make small changes. Big jumps look harsh and can clip detail.
- Raise brightness for dim photos, but watch that highlights do not blow out to pure white.
- Add contrast to revive a flat image, but keep shadows from crushing to solid black.
Finish the edit
After adjusting, sharpen as a last step with the Sharpen Image tool, then compress with the Image Compressor before sharing.
