Using PdfBox, how do I retrieve contents of PDDocument as a byte array?

Question

I am currently using PdfBox as the driver for a pdf-file editor application. I need the contents of the PdfBox representation of a pdf file (PDDocument) as a byte array. Does anyone know how to do this?

did you ever find out? I'd like to know too... – Martin Charlesworth Dec 06 '12 at 22:02 — Martin Charlesworth, Dec 06 '12 at 22:02

I hope it's not too late...

ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
document.save(byteArrayOutputStream);
document.close();
InputStream inputStream = new ByteArrayInputStream(byteArrayOutputStream.toByteArray());

And voila! You've got both input streams!

sorry for the late response. – Gabriel Ruiu Feb 06 '14 at 08:58
The answer is correct, at least for the version of PDFBox that I checked (1.8.4) – Gabriel Ruiu Feb 06 '14 at 08:58
Working fine in org.apache.pdfbox:pdfbox:2.0.4 – vinS Jun 06 '18 at 07:15

Works also fine in the latest available version (2.0.23) – Gianmarco F. Apr 23 '21 at 09:54
You saved me. The PDFMergeUtility is an effin' mess in the 2.0.* and was unable to merge PDDocuments with Type0 Fonts. So I saved both files in a stream and then could merge them later as inputstreams. – ak.leimrey Jun 06 '21 at 21:57
@ak.leimrey - Do you mind sharing the bits you used for merging? Thanks – yardie Oct 22 '21 at 13:17
