Home › Image Tools › Black and White Image Converter
A proper luminance-based grayscale conversion — the way photographers do it, weighted toward how the eye sees brightness — plus a contrast slider to make the result punchy or soft. Converted in your browser, downloaded at full size.
Simply draining color often leaves a flat, muddy picture, because colors that looked different can share the same brightness (a red shirt and green grass can land on the same gray). Raising contrast separates the tones and is the difference between "gray photo" and "black and white photograph". Try 1.1–1.3 for portraits and documents.
No — once saved, the color information is gone. Keep your original; the conversion only ever produces a new file.
