Grayscale a PDF to save ink
Print in mono and spare the colour cartridge, without uploading.
Colour ink is expensive, and most documents do not need it. Converting to grayscale before printing means your colour cartridge lasts longer. This tool does it in the browser, so the file is never uploaded.
