## Overview

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.

## Inputs

- **Image File** (file): Upload any image file (JPEG, PNG, WebP, GIF, BMP, TIFF) for gamma correction
- **Gamma Value** (range): Gamma correction (0.1 = darker, 1.0 = original, 3.0 = brighter)
- **Output Format** (select): Choose output format or keep original. PNG recommended for maximum quality
- **Quality (1-100)** (number): Output quality for lossy formats (JPEG, WebP). Higher = better quality but larger file size

## When to use

- Correcting images that appear too dark or washed out due to improper exposure settings.
- Adjusting the luminance of mid-tones to improve detail visibility in shadows.
- Preparing images for display on different monitors to ensure consistent brightness levels.

## How it works

- Upload your image file (JPEG, PNG, WebP, GIF, BMP, or TIFF).
- Adjust the Gamma Value slider: values below 1.0 darken the image, while values above 1.0 brighten it.
- Select your preferred output format and quality settings.
- Process the image and download the corrected version.

## Use cases

- Restoring detail in underexposed photographs.
- Balancing image brightness for consistent web design assets.
- Fine-tuning image contrast for better print output.

## Frequently asked questions

### What is gamma correction?

It is a non-linear operation used to encode and decode luminance in images, effectively adjusting the brightness of mid-tones.

### How does the gamma value affect my image?

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.

### Which output format should I choose?

PNG is recommended for maximum quality, though you can choose JPEG or WebP if you need to optimize for file size.

### Does this tool change the resolution of my image?

No, this tool only adjusts the brightness levels and does not alter the dimensions or resolution of your file.

### Is there a limit to the file size I can upload?

Yes, the maximum supported file size for processing is 10 MB.
