How Color Values Become Grayscale

Each pixel is converted using weighted RGB brightness: 0.299R + 0.587G + 0.114B. Different source colors can therefore become different gray values.

RedRGB 255, 0, 0 Gray level 76
GreenRGB 0, 255, 0 Gray level 150
BlueRGB 0, 0, 255 Gray level 29
YellowRGB 255, 255, 0 Gray level 226

These are example single-pixel conversions. The filter does not add a contrast curve, film grain, or local adjustments.

How to Apply the Black-and-White Filter

  1. Upload a color photo. Choose the image you want to convert to grayscale.
  2. Apply the weighted grayscale filter. Select Apply Black & White to convert the full canvas using each pixel's RGB brightness.
  3. Review and download. Check tonal separation in the result, then download it from the editor.

What Changes in the Image

The filter calculates gray as 0.299R + 0.587G + 0.114B, then writes that value to all three color channels. It applies to the whole image in one step, keeps the canvas dimensions, and has no mask or contrast slider.

Brightness-weighted values
Red, green, and blue contribute different amounts to each pixel's gray level.
Full-canvas effect
This tool converts every pixel; it does not offer a selective region or brush mask.
Dimensions stay the same
The filter changes color values but leaves the canvas width and height unchanged.
A grayscale base for tinting
Color Tint can add one warm hue across the full image for a sepia-like wash.

Frequently Asked Questions

Can I convert only part of the photo?

No. Apply Black & White converts the full canvas. It does not include a selection or local mask.

Can I adjust contrast on this page?

No. This is a one-step grayscale conversion without a contrast slider or film-grain control.

Does it resize the image?

No. The width and height remain unchanged; the filter changes pixel color values.
