Tool usage guide
Image Gamma Correction allows you to non-linearly adjust the brightness of your photos, ensuring that mid-tones are balanced correctly for optimal visual perception without washing out highlights or crushing shadows.
Background
A series of landscape photos were taken in low-light conditions, resulting in dark mid-tones.
Problem
The images look too dark, hiding important details in the shadows.
How to use
Upload the image and set the Gamma Value to 1.5 to lift the mid-tones.
gamma: 1.5, format: PNGOutcome
The mid-tones are brightened, revealing hidden details without overexposing the highlights.
Background
A set of PNG icons appears too bright when displayed on a dark website background.
Problem
The icons lack depth and contrast against the dark UI.
How to use
Upload the icons and apply a Gamma Value of 0.8 to darken the mid-tones.
gamma: 0.8, format: WebP, quality: 90Outcome
It is a non-linear operation used to encode and decode luminance in images, effectively adjusting the brightness of mid-tones.
A value of 1.0 is the original. Values below 1.0 make the image darker, and values above 1.0 make the image brighter.
PNG is recommended for maximum quality, though you can choose JPEG or WebP if you need to optimize for file size.
No, this tool only adjusts the brightness levels and does not alter the dimensions or resolution of your file.
Yes, the maximum supported file size for processing is 10 MB.
The icons appear richer and integrate better with the dark theme of the website.
