How to convert a PDF to grayscale
- Upload one or more PDFs.
- Choose the quality: draft, normal or high.
- Click Convert and download the grayscale PDF.
Color cartridges are expensive and many documents don't need color at all: course notes, slides to proofread, invoices, plans. This tool converts every page to grayscale so your printer uses black ink only. It also helps when an office or print shop asks for a black-and-white file.
Pick the quality for the job: “Draft” for a light file to read on screen, “Normal” for most printing, “High” for small print or detailed diagrams.
Good to know: to get a reliable result, each page is turned into a grayscale image, so the text is no longer selectable or searchable. If you need that, run the file through the OCR tool afterwards. Files are deleted after 30 minutes.
Frequently asked questions
Will the text still be selectable?
No, pages become grayscale images. Run the OCR tool afterwards if you need to search or copy the text.
Which quality should I choose?
“Normal” suits most documents. Use “High” for small print or drawings and “Draft” for a lightweight file.
Will the file get bigger?
It depends: at high quality a mostly-text PDF may grow. You can compress it afterwards.
Can I convert several PDFs at once?
Yes, up to 50 files in one go.
Is it free?
Yes, free with no sign-up.
