BLACK AND WHITE IMAGE

Convert an image to grayscale or black and white

Convert PNG, JPEG, or WebP images to grayscale or threshold black and white locally, then inspect contrast before export.

Convert colour pixels to grayscale or strict black and white locally, with an adjustable threshold for the two-colour result.

01

Add the colour image

Choose, drop, or paste a PNG, JPEG, or WebP file and keep the source available for comparison.

02

Choose grayscale or black and white

Use grayscale for continuous tones. Use black and white for a two-colour result and adjust the threshold to decide which pixels become white.

03

Inspect contrast and export

Check faces, shadows, text, and transparent areas before generating the selected output format.

Grayscale keeps tonal steps

Grayscale removes hue while retaining intermediate brightness. It usually preserves photographs better than a strict two-colour conversion.

Threshold creates hard decisions

Black-and-white mode maps each pixel to black or white. Move the threshold when light text, dark faces, or shadow detail disappears.

Common questions

What is the difference between grayscale and black and white?

Grayscale contains many brightness values. Black-and-white mode contains only two tonal outcomes determined by the threshold.

Why did detail disappear in black-and-white mode?

Pixels on the same side of the threshold become identical. Adjust the threshold or use grayscale when continuous detail matters.

Will transparency remain transparent?

PNG and WebP output can keep alpha. JPEG fills transparent pixels with the selected background colour.
