PDFcraft converts color PDF documents to grayscale or black and white for free — instantly in your browser. No sign up, no file uploads. Reduce file size and prepare documents for black and white printing.

What does the PDF to Grayscale tool do?

The free PDF grayscale converter removes all color information from your PDF document, converting every page to black, white, and grey tones. This reduces file size since grayscale images contain less data than color images. The conversion preserves all text, layout, and image content — only the color information is removed. Processing runs locally in your browser — your files never get sent anywhere.
