How to Adjust Image Brightness
Make a photo lighter or darker in three steps:
Step 2
Move the Brightness Slider
Open Finetune and select Brightness. Move the slider right to brighten the image or left to darken it, watching the preview as you adjust.
Step 3
Preview and Save
Check both bright and dark areas, then click 'Save' to download the edited result as a PNG file.
Brighten Dark Photos
Increase brightness when an image looks too dark overall. Make gradual adjustments so important highlight areas remain visible instead of turning flat or white.
Reduce Excessive Brightness
Lower brightness when a photo feels harsh or overly light. For a camera exposure problem, compare this control with Exposure; brightness is best for a straightforward overall lightness change.

Open the control you need, preview the change, and save the result without navigating a complex desktop editor.
