Tool for PDF conversion to black and white [closed]
Is there a freely available (preferably open source) tool or library for PDF conversion to black and white?
Some customers want to print generated PDF documents in B&W to save toner. Unfortunately I cannot generate PDF in B&W directly, since we are merging two PDF pages together, one being official not available in B&W.
Update: To be more specific, I am looking for automatic solution, i.e. tool that is callable from a program.

With PrimoPDF (http://www.primopdf.com/index.aspx) you should be able to set to generate a "Black & White" pdf.
"Printing Preferences" -> "Paper/Quality" tab, then you can choose between "Black & White" and "Color.
Having seen Viliam's insisting on wanting "Black and White", not "Grayscale" I'm still offering this solution to convert PDF files to grayscale. Because I think that would perfectly fullfil the requirement to "save color toner" and make use of black toner only.
Use Ghostscript (the most recently released version is 9.05) with this command:
On Windows, use gswin32c.exe or gswin64c.exe instead of gs . Ghostscript meets Viliam's request for:
and it does the job.
If color conversion does not work as desired and if you see a message like "Unable to convert color space to Gray, reverting strategy to LeaveColorUnchanged" then.
- your Ghostscript probably is a newer release from the 9.x version series, and
- your source PDF likely uses an embedded ICC color profile
In this case add -dOverrideICC to the command line and see if it changes the result as desired.
