I am seeking Windows OS software that can open a multi page PDF as a raster image (thus treating it like a multi page TIFF) and then export it back out as a PDF (ignoring all the original vector info it may have had; saving what it now considers to be a multi page raster image as a multi page PDF).
It needs to be able to do so at an original PDF-to-raster resolution of at least 300 dpi.
This is not for personal use, so (unusually), instead of freeware being best, it might be better if it were inexpensive but commercial in nature. (But I would still want to know about freeware or shareware that would do the trick, nevertheless).
Mac equivalent would be Graphic Converter. I’ve verified that I can do the stunt with Graphic Converter but they will want to be able to do this on Windows machines.
Depending on what PDF reading software you have, you can export or save as all your pages as bitmapped images. Then reimport them into your pdf reader.
If a program’s license is truly open, you can totally use it for commercial purposes. In your case, ImageMagick will do the job, specifically, the “convert” tool.
This actually did the trick. Not when I exported then reimported as TIFF – for unknown reasons that replicated the same problem for the same exact images (long story, weird stuff); but it worked when I did it with PNG format, specifying 300 dpi.
With the standard Acrobat, you can print directly to an image and save it as a PDF (rasterizing everything, including text, at whatever DPI you choose). It’s simple and one-step, which may save you time if you do this frequently:
It costs $15/mo though, so only worth it if you actually use it often.
