Adjust Image Gamma Correction

Gamma Correction Image Tool

Drop an image into the tool and change the Gamma Correction percentage to increase the luma intensity, then preview the improved image. Download the pictures once the required gamma encoding level is obtained.

How to Adjust Image Exposure

1. Upload your photo and wait for the upload to complete.
2. Move the slider to the desired level of the image gamma you need.
3. Click the ''Convert' button to process the image.
4. After editing, you can easily download the new photo file to your device.

Drag the slider to change the gamma correction of an image. Increasing gamma makes images darker. Decreasing gamma lightens the highlights and lightens the shadows.
