How to convert a multi-page PDF file to PNG files, with one PNG file per page of the PDF document?
Using ImageMagick (you'll need Ghostscript installed as well), the command:
convert -density 300 filename.pdf filename.png
will result in a series of files filename-0.png
, filename-1.png
, filename-2.png
, one for each of the pages of the PDF. You'll want to play around with the density setting to get a resolution you like.
You may need to give the full path to convert.exe on Windows; I've only ever done this on Linux, but it should work for Windows too.
Use Ghostscript
-sOutputFile=filename This is a general option telling Ghostscript what to name the output. It can either be a single filename 'tiger.png' or a template 'figure-%03d.jpg' where the %03d is replaced by the page number.
You may find it convenient to use GhostView, the GUI front end.
You can use PDF-XChange. It can export any pages you want to the expected format. Not only PNGs but many other formats are supported too
