How to brighten a dark image

Increase brightness until the important parts of the photo are easier to see, then compare the preview before exporting. If very bright areas start to look washed out, reduce the brightness amount or use the full Adjust Image tool for more control over exposure, highlights, and shadows.

Brightness vs exposure

Brightness is the simpler choice when the whole image only needs to look lighter. Exposure is a stronger light adjustment and is available in the broader adjustment tool when a single brightness slider is not enough.

Limitations

  • Brightness is an overall adjustment. If only highlights or shadows need work, use the broader Adjust Image tool.

Questions

How can I brighten a dark image?

Choose the image and increase the Brightness control until the important details are easier to see, then export the result.

What is the difference between brightness and exposure?

Brightness is a direct overall lightness adjustment. Exposure is a stronger light adjustment available in the broader Adjust Image tool.

Why can a brightened image look washed out?

Increasing brightness too far can make already-bright areas lose visible separation. Reduce the amount or use highlights and exposure controls in Adjust Image for more control.

Can I reset the brightness change?

Yes. Move Brightness back to zero or use Reset before downloading the image.

Which formats can I download after brightening?

You can export the brighter image as PNG, JPG, or WebP.

Is the image uploaded when I brighten it?

No. The selected image and brightness preview are processed locally in your browser.
