Three Classic Looks
Grayscale keeps tonal detail using a perceptual weighting of red, green and blue. Black & White is a hard threshold that turns every pixel pure black or pure white — ideal for scanning line art and printing. Sepia applies a warm brown tone for a vintage feel.
All conversions run per pixel on an HTML canvas in your browser, so the result is instant and private.
