## Overview

The Image Binary Converter allows you to transform any color or grayscale image into a high-contrast monochrome format. By applying a specific threshold value, you can isolate shapes, simplify complex visuals, or prepare images for OCR and stencil printing.

## Inputs

- **Image File** (file): Select an image file...
- **Threshold Value (0-255)** (number): Pixels with value >= threshold become white, others become black
- **Invert Result** (checkbox): If checked, black and white colors will be inverted

## When to use

- Preparing images for optical character recognition (OCR) to improve text detection accuracy.
- Creating clean, high-contrast stencils or line art from detailed photographs.
- Reducing image file complexity for technical documentation or simplified graphic design assets.

## How it works

- Upload your source image file in JPEG, PNG, WebP, GIF, BMP, or TIFF format.
- Set a threshold value between 0 and 255 to define the cutoff point for black and white pixels.
- Toggle the invert option if you need to swap the resulting black and white areas.
- Process the image to generate and download your new binary file.

## Use cases

- Isolating text from scanned documents for better readability.
- Generating simplified silhouettes for logo or icon design.
- Creating high-contrast masks for image editing workflows.

## Frequently asked questions

### What does the threshold value do?

The threshold determines the brightness cutoff. Pixels with a value equal to or greater than the threshold become white, while those below it become black.

### Can I invert the colors of the output?

Yes, checking the 'Invert Result' box will swap the black and white pixels in your final image.

### What file formats are supported?

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

### Is there a file size limit?

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

### Does this tool support batch processing?

No, this tool is designed to process one image file at a time.
