I have a folder full of images in PDF format, and I would like to merge them all into a single PDF in which there are many images on each page, but still in vector/PDF format. The ImageMagick 'montage' command almost does this, but it actually converts them all to raster images first. I want to be able to create a contact-sheet that's still in vector format, so I could specify 16 PDF files, and it will return a one-page PDF with 16 scaled images on it.

Any ideas?

Ghostscript supports PDF/PS files and should maintain the vector qualities (can also rasterize as well).

gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=newName.pdf {1,2,3,4,5}.pdf

Do you have Acrobat Pro?

  1. Select all the files you want to combine.
  2. Right click and select Combine supported files in Acrobat. Gives you some options in a dialog box, pretty straight forward.
  3. Click Combine Files. This gives you a single pdf.

When you have the combined files in a single pdf, print using the Adobe PDF driver. In the Print Dialog Box:

  1. For Page Scaling, select Multiple pages per sheet.
  2. Then specify the Pages per sheet.
  3. Print. This will give you a single sheet pdf with the number of pages you specified.
