Convert PDF to grayscale
Upload your PDF and convert every colour to grayscale (black & white) in one go. Ideal for cheaper printing and crisp black & white output — your fonts stay embedded and the layout stays exactly the same.
The difference
Converting a colour PDF to black & white is a hassle
- In Acrobat or a design app, grayscale conversion is buried in pre-flight menus.
- Print a colour PDF on a black & white printer and the driver decides the conversion — often dull and inconsistent.
- The printer charges for colour while your document is really black & white.
- Converting page by page or image by image by hand takes time and goes wrong.
Pure grayscale in one click
- Upload your PDF and we convert every RGB and CMYK colour to grayscale (DeviceGray).
- A predictable, consistent black & white result on every printer and press.
- Text, vectors and layout stay sharp; fonts stay embedded.
- Multiple files at once — you get a ZIP back.

Frequently asked questions
What does converting a PDF to grayscale mean?
It converts all colours (RGB or CMYK) to shades of grey, so the PDF only contains black, white and grey. The layout, text and page dimensions stay the same.
Will my text stay sharp?
Yes. The conversion only changes the colour space, not the resolution or vector text. Text and lines stay as sharp as in the original.
Are images converted too?
Yes, colour photos and illustrations are converted to grayscale as well. The result is a fully black & white document.
Does it use credits?
Yes, 1 credit per file. New accounts start with free credits so you can try. With multiple files you receive a ZIP.
Which files can I upload?
PDF files and ZIP archives containing PDFs. You can convert up to 200 files at once.
