The Portable Document Format (PDF) is a document format from Adobe Inc. It is widely available on the web. Originally developed as a propriety format, it was released as an open standard in 2008. The standard is published as ISO/IEC 32000-1:2008.


Each file begins with the string %PDF. Each block ends with the letters EOF, but there can be multiple EOF's in a single file (this often confuses programs like foremost that search for footers).


The metadata (or parts of it) can be extracted with pdfinfo, a utility which is part of the xpdf package.

Embedded Objects

You can use pdfimages, part of the xpdf, to extract all of the images out of a PDF file and put each in its own file.
