Google or Bing: how to display a color pdf to grey

Grey scale is the normal conversion for color. Black and white are only two colors that do not work well for images, but is OK for line drawings and text only.

I tried that and an online converter made no difference. But that was only one. I'll try harder now. Thanks

Here are a few links:

Converting Color PDF to Greyscale PDF (An Update)

 

From <https://blogs.adobe.com/acrolaw/2009/10/converting-color-pdf-to-greyscale-pdf-an-update/>

 

Can I use snagit to enhance a greyish PDF?

Snagit can print color PDF as Gray!!

From <https://feedback.techsmith.com/techsmith/topics/can-i-use-snagit-to-enhance-a-greyish-pdf>

 

Have you ever had a color PDF file that you needed to convert to grayscale? Acrobat 8 Professional has a simple-but-not-obvious way to accomplish this.

From <http://blog.gilbertconsulting.com/2007/05/convert-color-pdf-to-grayscale.html>

 

Sometimes it can be useful to convert a color PDF to grayscale. If a PDF file contains many color images and file size is essential but color isn’t, the conversion saves space. If a PDF will be printed in B/W then converting it allows you to visually check what the end result will look like.

From <https://www.prepressure.com/pdf/basics/editing/convert-color-to-grayscale>

 

I have SnagIt V-13, and I will try it if you are interested.

Yes please Walt. I've never used the PM service on this forum but I'll give it a try.  Otherwise does Rusty or Danny have your email..? I can send them to send to me if you know what I mean.

I remember snagit  -- such a cool little program. Now there is snipping tool, no where near as powerful but it will do -  until now!

Give this one a try...http://greyscalepdf.com/

If you need to do this frequently you might investigate WIN2PDF at http://www.win2pdf.com/.  There is also a trial version that might be what you need for a one time thing.  WIN2PDF installs as a printer so on my PC, where I have a full copy of WIN2PDF, I just reprint an open PDF and select "convert to greyscale".

Years ago I also used something similar to WIN2PDF.  IT was called PDF995 and can be found at http://www.pdf995.com/.  The basic version is still free.

Vibe-Rater,

I responded to your private message with a grayscale PDF from the color PDF you sent. I used Techsmith SnagIt-13 that I primarily use for screen captures, some annotations and screen video capture for training others. A very good program with low cost and excellent technical support! I did not see or try John-PA suggestions, but looks good as well.

Hi Walt, yes I received, thank you very much. Nice job.  My copy of Snagit is REALLY old and wont run on 64 bit. The "Snipping Tool" cam along with 7 I think it was.  But of course that does not B&W pdfs.  If I need to convvert again will jjust buy snagit. rgds

Hi John, tried the first link but it returned the same colour.  By that time Walt had converted with his Snagit so I didn't try the 2nd link. Very grateful for your help nonetheless. rgds.

Out of curiosity, I tried another method to get gray PDF. I opened the color PDF file with Bluebeam PDF Revu and then selected Print to Bluebeam PDF Revu and selected Printer Properties >Paper Quality >Black& White and then gave a new file name for the gray version of the PDF. Bluebeam has very good Markup tools, for example to add color codes to gray drawing or photo of a machine.
