How to darken an image online?

Select your file, drag the darken slider to reduce luminance, then export the result.

When should I use Darken instead of Brightness Adjust?

Use Darken when you only need to make an image deeper or moodier. Brightness Adjust is better when you want one slider for both lighter and darker changes.

Can Darken help with overexposed photos?

Yes. Darken can tone down bright images, but severely clipped highlights may not recover lost detail.

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.
