Frequently Asked Questions

Common questions about black & white conversion

What is the difference between black & white and grayscale?

Black & white conversion produces only pure black and pure white pixels, creating a high-contrast monochrome look — ideal for documents and bold prints. Grayscale keeps smooth shades of gray in between. We offer both tools; this one is for true black and white.

Can I adjust the threshold?

Yes. Use the threshold slider to control the cutoff point between black and white. A lower threshold makes more of the image black; a higher one makes more white.

Which output formats are supported?

You can download your black and white image as PNG, JPG, or WEBP — whichever fits your needs best.

Is it secure?

Your privacy is our priority. All conversion happens locally in your browser — your images are never uploaded to any server, so they never leave your device.
