About this tool
This page opens the photo filter tool with the grayscale effect already selected — drop in your picture, fine-tune the intensity and download the black-and-white version.
The conversion is a real per-pixel operation: each pixel's red, green and blue values are replaced with their luminance-weighted average, so bright and dark tones keep their natural balance. The intensity slider blends the result with the original — at 100% you get a clean monochrome photo, lower values leave a hint of the original color for a faded, vintage look.
The full tool also offers sepia, color inversion and a pencil sketch effect. Everything is processed locally in your browser, so your photos never leave your device.
Example. Grayscale at full intensity rewrites each pixel from its red, green, and blue channels into a single gray level, and the slider blends that result back toward the original.
Limit. The effect list is grayscale, sepia, invert, and pencil sketch only.
