Convert PDF to grayscale
Turn a color PDF into grayscale (black and white) for free — ideal for cheaper printing and smaller files, entirely in your browser. Your file is never uploaded to a server.
How to convert a PDF to black and white
- Open the Grayscale tool and add your PDF — drag and drop it, or click “Choose files.”
- Convert. Every page is rendered in grayscale.
- Download. The black-and-white PDF is generated on your device and saved to your Downloads folder.
Grayscale a PDF without uploading it
The document tools process file contents in your browser rather than uploading them for processing. Working files remain in page memory; downloads remain wherever you save them. Informational pages may load ads or analytics; the document-opening page excludes them. Read the privacy policy for details.

Grayscale PDF — FAQ
Is converting PDFs to grayscale free?
Yes — it's completely free, with no sign-up and no watermark.
Are my files uploaded when I convert?
No. The conversion happens entirely in your browser; file contents are not uploaded for processing.
Does grayscale make the file smaller?
Often, yes — removing color usually reduces file size. For the smallest file, run the Compress tool as well.
Will the text still be selectable?
Pages are re-rendered as grayscale images, so text becomes part of the page image. Use OCR afterwards if you need selectable text.
