PDF to grayscale: what it is and when to use it
Converting to grayscale removes the color from every page of the PDF. It helps you print in black and white with better contrast and less ink.
Printing a color PDF uses ink, sometimes unnecessarily. Converting it to grayscale removes the color from every page, improves contrast in black and white, and cuts printer costs.
Truly private
Your files are processed on your device and never uploaded to a server.
Rayo PDF GO regenerates each page in grayscale and saves the result as a new PDF. Because each page becomes an image, the text can no longer be selected; if you need it searchable, run the result through OCR.
The process runs on your device: the document is never sent to a server.
Common uses
Print reports and notes without using color ink.
Prepare a document for black-and-white photocopying.
Unify the look of a PDF with elements in many colors.
Send a clean, uniform-contrast version to the printer.
Tips for better results
- Check the preview before converting.
- To also reduce the size, run the result through Compress PDF.
- Keep the original in color in case you need it later.

Are my files uploaded?
No. Everything happens on your device.
Is it free?
