Threshold Image Converter

Turn a photo or graphic into pure black and white pixels with an adjustable luminance threshold and optional inversion.

Upload an image to create a two-color black and white threshold result.

Pure black and white

Every visible pixel becomes either zero or 255 instead of grayscale.

Adjustable cutoff

Control which luminance values become white with a 0 to 255 threshold.

One-click inversion

Swap black and white without changing the source image.

Choosing a threshold level

Start near 128, then lower the threshold to make more pixels white or raise it to make more pixels black. High-contrast source images give clearer silhouettes, logos, and stencil-style results.
