What the brighten tool does

It lifts the exposure and the shadows so faces and details are clearly visible, with natural colors and white balance, as if the photo had been taken in better light.

The people, the faces, the clothes, and the scene stay the same.

Photos that work well

A photo that is too dark but still shows the faces and the main shapes.

Good light on the photo you already have

One upload, no curves or sliders.

  1. 01

    Faces first

    Shadows on faces are lifted so people are easy to see.

  2. 02

    Natural colors

    White balance is corrected without washing out the bright parts.

  3. 03

    No watermark

    Free runs export a JPG up to 2048 px. Runs paid with credits keep the model's full size.

What it does not do

  • It redraws the photo rather than moving a slider, so very small details can shift. For an exact edit, your phone's photo editor is still the right tool.
  • It cannot recover a photo that is almost black, and it does not remove blur or noise; for that, use the Photo Enhancer.
  • Our example photos were darkened by us to simulate underexposure. The brightened versions are real runs.
  • Uploads and results are deleted after 24 hours (7 days if you're signed in). The photo is sent to the model provider so the edit can run.

Need further adjustments?

If you're happy with the result, it's ready to save. If you also want to upscale, extend the edges, or refine other details, you can continue with:
