Knowledge Base
Grayscale conversion removes color information, converting each pixel to a shade of gray based on its luminance. The result is a black and white image.
Yes. Grayscale images contain less color data so they compress more efficiently. Run through our compressor after conversion for maximum size savings.
The spatial resolution is fully preserved. Grayscale only removes hue and saturation. The output has the same sharpness and detail as the original.
All formats are supported: PNG, JPEG, WebP and AVIF. PNG and WebP produce the best grayscale results due to lossless or near-lossless compression.
