## Overview

The Image Boolean NOT tool allows you to instantly invert the colors of any image by applying a bitwise NOT operation to every pixel. This process creates a photographic negative effect, effectively reversing the color values to produce a high-contrast, inverted version of your original file.

## Inputs

- **Image File** (file): Image to apply NOT operation (invert all pixels)
- **Output Format** (select): Output format for the result image
- **Quality (1-100)** (number): Output quality for lossy formats

## When to use

- When you need to create a photographic negative effect for artistic or design projects.
- When you want to analyze image features that are more visible in inverted color spaces.
- When you need to quickly reverse color schemes for UI mockups or graphic assets.

## How it works

- Upload your source image in any supported format like PNG, JPEG, or WebP.
- Select your preferred output format and adjust the quality settings if necessary.
- Click the process button to apply the bitwise NOT operation to all pixel data.
- Download your newly inverted image file immediately.

## Use cases

- Generating negative versions of icons or logos for dark-mode design testing.
- Processing scientific or medical imagery to highlight specific contrast-dependent details.
- Creating stylized visual effects for digital art and photography portfolios.

## Frequently asked questions

### What does the Boolean NOT operation do to an image?

It performs a bitwise inversion on each pixel's color value, effectively turning light areas dark and dark areas light, similar to a film negative.

### Which image formats are supported?

You can upload JPEG, PNG, WebP, GIF, BMP, and TIFF files.

### Can I change the file format of the output?

Yes, you can choose to keep the original format or convert the result to PNG, JPEG, or WebP.

### Does this tool affect image quality?

The inversion process is mathematically precise. If you choose a lossy format like JPEG, you can adjust the quality slider to balance file size and visual fidelity.

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

Yes, the tool supports files up to 10MB in size.
