About the Black and White Image Converter
The Img Stop Black and White Image Converter turns colour photos into monochrome the way photographers do it, not just by throwing the colour away. Choose how the grays are calculated (luminosity, average or desaturate), or simulate the red, orange, yellow, green and blue glass filters used with black-and-white film to control how skies, skin and leaves turn out.
Six ready-made looks get you started, from a clean classic grayscale to a grainy, high-contrast noir with dark corners and a warm sepia print. For logos, signatures and stencils, the threshold mode makes every pixel pure black or pure white, with a manual level or an automatic one. Everything runs in your browser, even for a whole batch.

Frequently asked questions
How do I convert a picture to black and white?
Add the picture to the Img Stop Black and White Image Converter, keep the Classic look or choose another one, and click Convert to black and white. Download the result as JPG, PNG or WebP.
What is the difference between luminosity, average and desaturate?
Luminosity weights red, green and blue the way our eyes see brightness, so it looks most natural. Average treats all three equally, and Desaturate uses the midpoint of the brightest and darkest channel, which often looks flatter.
What do the colour filters do?
They copy the coloured glass filters used on black-and-white film cameras. A red filter makes red and orange areas lighter and blue skies darker; a green filter lightens foliage; a blue filter darkens warm tones for a moody look.
Can I make an image pure black and white with no gray?
Yes. Choose Pure B&W or set Result to “Only black & white”. Move the threshold slider or tick Automatic level to let the tool find the best split for that image.
Can I convert many photos at once?
Yes. Add as many photos as you like; the same settings are applied to all of them and you can download everything as a ZIP.
Are my photos uploaded?
No. The conversion happens on your device in the browser.
