Convert pdf to png
December 9, 2012 12:04 AM   Subscribe

I have a 1200 page pdf file that I'd like to convert to png image files. I would like each page of the pdf to be converted to a separate png file. What's the easiest way to achieve this? I'm using Windows.

1. Just a quick google gave me the following (assuming, and this is a big if, that your PDF is under 25 MB): http://pdf2jpg.net/ to convert the pdf to jpg.

2. Use 'convert' http://www.imagemagick.org/script/convert.php (these tools are magic, and awesomesauce) in a command line as follows:

for %I in (*.jpg) do convert "%~nI.jpg" "%~nI.png"

If your PDF is larger than 25MB (note: I haven't tried the service in step #1) you'll have to find a different solution for step #1, but step #2 will work for other image types as well.

I was about to abuse the edit window to add a reference to this tool for offline conversion of the pdf to jpg: http://sourceforge.net/projects/pdf-to-jpg/.

I haven't used the tool and can't vouch for it. (but I'll give another shout out to the utility of imagemagick).

PDFcreator is a (free) virtual print driver, and this page says it'll save one PNG per printed page.

Imagemagick is great, it's the swiss army chainsaw of image manipulation - see here for the one-shot solution.

I used imagemagic on a job like this a few years back. Was an easy answer - I also use PDF creator. Both are good solutions.

PDF-Xchange Viewer will do this for you very easily as well.

If you have access to Adobe Acrobat, this is incredibly easy to do. With this many pages, I'd split the document into 4 parts. Then export to PNG by going through the menus: File > Export > Image > PNG

OOOH I just did this, although not on Windows. ImageMagick would normally be the go-to answer, but I had some severe resolution degradation when I used it for this purpose. Instead I went with pdftoppm which can also output PNG. The usage is command-line, but extremely simple:

pdftoppm -png YourFile.pdf Output

This will result in a sequential series of PNG files starting with the word Output.

Here's the software to download that includes the pdftoppm utility.

Download a free trial of Acrobat XI Pro (30 day trial). Do the basic signup if need be. There will be no need to give any financial info, just an email at most.

Get the file into a folder and open in AcroPro.
Use the following menu choices.

FILE>>SAVE AS OTHER>>IMAGE>>PNG

Give the initial page a name, the rest will be sequentially named and exported as separate files.

Go get some coffee while it grinds through. Repeat as necessary.
