Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

split a multi-page PDF into separate files

Have to do this once per output file, because if device is 'pdfwrite', even if 'gs' sees '%d' in the OutputFile it still only creates one single output file. Embed it into a simple shell script if you want to split a document out into one file for every page.

Simple alternative to the previous submitted one

Know a better way?

If you can do better, submit your command here.

What others think

using ghostscript (gs) for pdf management is convenient and will work fine, but just remember it converts to postscript and back to work which can mangle some things, but more importantly will re-compress any embedded images inside the PDF, use pdftk or stapler instead for lossless pdf cat and burst.

I needed just such a PDF file splitter tool, last week. i downloaded and used the free PDF Split and merge Tools at [http://exchangerecovery.hubpages.com/hub/mergepdf] and it worked. Try it.....!
