How to split a PDF using Apache PDFBox?

Question

I am using Apache PDFBox to handle PDF files in my Java application. I would like to split a PDF document, for example, on every page.

Is it possible to do this wirth Apache PDFBox? If so, how?

For some advanced splitting, see here: https://stackoverflow.com/questions/32002830/how-to-split-pdf-file-by-result-in-java-pdfbox Btw in the future, consider a google search before asking a one-line question. Searching for "pdfbox split" in google finds just the class from the answer by Tunaki. — Tilman Hausherr, Aug 27 '15 at 22:07

This is possible using a Splitter.

This is a sample code that will split a document on every page:

PDDocument document = PDDocument.load(myPDF);
Splitter splitter = new Splitter();
List<PDDocument> splittedDocuments = splitter.split(document);

You can control the number of pages on every splitted PDF using setSplitAtPage(split).

This is called Generics. You should look at a [tutorial](https://docs.oracle.com/javase/tutorial/extra/generics/index.html) about it. – Tunaki Aug 27 '15 at 21:05

@ShaheedulIslam It means a list of PDDocument elements. – Tilman Hausherr Aug 27 '15 at 22:09
And I am hoping that splitting PDF like this won't cause loss in any internal structure tree (tags to be precise). – Pramesh Bajracharya Aug 26 '19 at 06:04
Do you have to close every instance os splittedDocuments or just close document? I'm doing only the latter and see lots of warnings: Warning: You did not close a PDF Document – maxi Feb 06 '20 at 19:28
