Black and White Image Converter
Quick Start

Convert photos and images to black and white.

Black and White Image Converter lets you upload photos or other images, choose grayscale or true black and white, fine tune the look, and download the finished files together in one ZIP folder.

How To Use

  1. Add images by browsing, choosing a folder, or dragging files into the upload area.
  2. Choose Grayscale for smooth black and white tones or True Black and White for a hard threshold effect.
  3. Use the sliders to adjust brightness, contrast, threshold, blur, sharpen, invert, and transparency handling.
  4. Review the first-image preview.
  5. Select PNG, JPG, or WebP as the output format.
  6. Click Download ZIP to process and download the finished files.

Slider Notes

  • Brightness makes the final result lighter or darker.
  • Contrast increases or reduces the difference between light and dark areas.
  • Threshold controls where pixels become black or white in True Black and White mode.
  • Blur softens the image before conversion.
  • Sharpen adds more edge definition after conversion.
  • Invert blends the result toward an inverted black and white version.
  • Transparency handling controls how much transparent areas are flattened onto white.
