About the Image Brightness Adjuster
Quickly fix underexposed photos or tone down images that are too bright. The adjustment works like the CSS brightness() filter: every color channel is multiplied by the same factor, so hues stay true while the overall exposure changes.
How to use it
- Move the slider: positive values brighten, negative values darken.
- Choose the output format.
- Drop your images and download.
Good to know
- Highlights that are already pure white cannot be recovered by darkening.
- For flat-looking photos, combine a small brightness boost with the Contrast tool.
