Frequently asked questions

How to lighten an image online?
Select your file, drag the lighten slider to increase luminance, then export the brighter image.
When should I use Lighten instead of Exposure Adjust?
Use Lighten for a simple brightness lift. Use Exposure Adjust when you want camera-like stop controls that multiply image light.
Can Lighten bring out shadow detail?
Yes. Lightening can reveal darker areas, though very noisy or crushed shadows may still need contrast or exposure adjustments.
Is this tool free to use?
Yes — completely free, no account needed. Your images are processed entirely in your browser and never uploaded to a server. Downloads have no watermarks.
