Is there any free way to split PDF pages down the middle?

[r4z0r84]

Understanding that this is an old thread, but as i do for all that have PDF issues with changing their scanned books or images or downloaded ebooks in pdf format.

I use the following programs, i have written a full guide to using them including pictures in docx format, i am unable to upload here so i'll just be pasting plain text.

PDF Scissors (PDF cropping program)
http://www.pdfscissors.com/
Click start PDF scissors, Java 6 window will pop up automatically downloading the application.
Click open select what PDF file you wish to crop or edit, by default the program will stack all pages together, if you wish to edit each page individually( good for minor changes) or every second page(useful for book scans to remove middle spine of book line)
Click OK, Wait for the program to do its thing.
You will now see all the pages stacked on top of each other if selected “all pages together”
Click and drag around the part of the document you wish to keep, if you are unable to select the entire portion you want, click and drag the dot points at the corners of the selection box.
When happy with your selection click save
The program has now successfully cropped your PDF
There are multiple other ways to use this tool, To sort PDF’s by showing pages individually and selecting the order one by one, Skip pages to delete them, Select multiple places on a single page to split them into multiple pages, Of course this tool is still best suited for cropping as it will take quite a long time to do all of the above, I suggest using the other programs below to do the above.

PDF Arrange (sort pages or move unwanted pages to the end so PDF Split can remove multiple)
http://www.softpedia.com/get/Office-tools/PDF/PDF-Arrange.shtml
Click Download, Either US or UK mirror. Click Save
Go to download location (default C:\Users\Your Username \Downloads)
Right click and extract then run PDFArrange.exe
Click Open, Select the PDF you wish to modify.
The page numbers will show in the left pane of the program, click and drag pages into the right order
You will have a preview in the right pane of the program these may not be accurate if you have used other modifying programs such as PDF rotate, The final result will not change the orientation from the original the previews are just a guide.
When happy with the order click save.

Enter page numbers from 1-10 for pages 1-10 in a single PDF (if there are 20 pages it will remove the last 10)
To select more than one section, Click +More
More than likely you will want to tick the “Merge the selected pages into a single file” this option will give you a single PDF with all the selected pages
If you want single pages tick the “Extract all pages into separate files” this option will extract all pages individually to give multiple outputs.

My 2-step solution

Thanks to everybody across the years who helped me find my solution. I do the cropping and cutting in PDF Scissors and some final trimming in PDF Rider.

It's kind of crazy to me that there isn't some open source suite that includes this type of operation.

If you really believe what you preach, just learn enough to create one and put it in the public domain yourself.

Otherwise, maybe what you really mean is "I think everybody else should give me stuff for free, but I'm not giving anything back in return".
