Convert a PDF to greyscale
This tool converts a colour PDF to true greyscale (black and white) using Ghostscript on our server. Unlike a screenshot, the text stays sharp and selectable — ideal for cheaper black-and-white printing or a cleaner look.
When to use it
- Prepare a PDF for black-and-white printing.
- Remove colour to reduce distraction or ink use.
- Standardise scanned documents to greyscale.
Private & secure
Your file is uploaded over an encrypted HTTPS connection, converted on our server and streamed straight back to your device. Each request runs in its own isolated workspace that is deleted the instant the result is returned, so nothing is ever stored or shared.
Frequently Asked Questions
Will the text stay selectable?
Yes. This is a true greyscale conversion, not a flattened image, so text remains sharp, searchable and selectable.
Are my files uploaded to a server?
Yes. Unlike our browser-based tools, the PDF to Grayscale runs on our secure server because it needs professional desktop-grade software to do the job well. Your file is processed in an isolated workspace and deleted automatically the moment the result is sent back — nothing is stored, logged or shared.
Is it free? Is there a watermark or size limit?
It is completely free with no sign-up and no watermark. Files up to 100 MB are supported per conversion.
