Black and White Image Converter

About This Tool

This tool converts a color image into a grayscale or binary black-and-white version, enabling consistent mono assets for design, publication, and accessibility workflows. It applies perceptual luminance weights to recreate tonal relationships, preserving structure while removing color. For binary output, you can set a threshold to determine which pixels become black or white, facilitating high-contrast silhouettes and masks. Gamma correction ensures midtones are retained according to perceptual expectations. The tool supports optional Floyd–Steinberg dithering to improve texture in low-contrast areas while maintaining a mono result. Input flexibility includes common image formats (JPEG, PNG, TIFF) and a PNG/JPEG output by default. The workflow is suitable for automated pipelines and manual edits, allowing batch-friendly integration through repeated single-file runs. Users benefit from predictable mono representations that fit branding guidelines, archival standards, and accessibility compliance where color information is not required.
