Adjust Image Gamma Online
Gamma correction changes the way midtones are mapped without applying a simple uniform brightness shift. It can reveal darker detail or soften bright midtones while keeping the image dimensions unchanged.
Example
A slightly dark photo adjusted from gamma 1.00 to 1.35 can make midtones easier to see while preserving the original width and height.
Factors That Affect the Result
The best gamma value depends on the source image's tonal range. Extreme settings can make shadows or highlights look flat, while moderate changes usually preserve a more natural balance. Gamma is different from brightness because it applies a nonlinear transformation.
Frequently Asked Questions
Is gamma the same as brightness?
No. Gamma mainly reshapes midtones using a nonlinear correction.
Does gamma adjustment resize the image?
No. Pixel dimensions stay the same.
Is the image processed locally?
Yes. Processing runs in your browser.

Adjusting Gamma
Gamma changes midtone brightness without shifting black and white points in the same way as a simple brightness control. Values should be adjusted gradually because excessive correction can wash out contrast or hide detail. Compare the preview with the original, especially in faces, shadows and textured areas.
Gamma Adjustment Notes
Gamma changes midtone brightness without affecting shadows and highlights exactly like a simple brightness control. Small adjustments can improve visibility in flat images, while extreme values may wash out or crush detail. Compare the edited version with the original before exporting.
Technical Details and Practical Limits
Gamma adjustment changes midtone luminance nonlinearly while leaving black and white endpoints comparatively stable. Excessive correction can wash out contrast or hide shadow detail, and results can differ depending on color space and display gamma.
