Gamma correction is a nonlinear operation used to encode and decode luminance values in images. It adjusts the overall brightness of an image by changing the relationship between the numerical pixel values and the actual brightness levels.
Use gamma adjustment when your images appear too dark or too bright, but you want to maintain detail in both shadows and highlights. It's particularly useful for correcting images that look different on various displays or when preparing images for different viewing conditions.
A gamma value of 1.0 means no change. Values less than 1.0 will brighten the image (especially mid-tones), while values greater than 1.0 will darken it. The adjustment follows a power law relationship, preserving more detail than simple brightness adjustments.
Unlike brightness (which shifts all values equally) or contrast (which stretches the range), gamma correction adjusts the mid-tones more than the extremes. This makes it ideal for correcting exposure without losing detail in highlights or shadows.
Start with small adjustments around 1.0. Most images benefit from gamma values between 0.8 and 1.2. For dark images, try values between 0.6-0.9. For overly bright images, try 1.1-1.4. Always check your adjusted image on different devices.
Our gamma adjustment tool supports all major image formats including JPG/JPEG, PNG, WebP, and GIF. The tool processes images locally in your browser, ensuring privacy and maintaining original image quality during export.
