The Apache PDFBox library is an open source Java tool for working with PDF documents. This project allows creation of new PDF documents, manipulation of existing documents and the ability to extract content from documents. PDFBox also includes several command line utilities. PDFBox is published under the Apache License, Version 2.0.
PDFBox is a project of the Apache Software Foundation http://www.apache.org/.
You can download binary versions for releases currently under development or older releases from our Download Page.
You need Java 7 (or higher) and Maven 3 http://maven.apache.org/ to build PDFBox. The recommended build command is:
mvn clean install
The default build will compile the Java sources and package the binary classes into jar packages. See the Maven documentation for all the other available build options.
There are various ways to help us improve PDFBox.
Please follow the guidelines at our Support Page.
If you have questions about how to use PDFBox do ask on the Users Mailing List. This will get you help from the entire community.
The PDFBox examples and the test code in the sources will also provide additional information.
And there are additional resources available on sites such as Stack Overflow.
If you are sure you have found a bug the please report the issue in our Issue Tracker.
See the issue tracker at https://issues.apache.org/jira/browse/PDFBOX for the full list of known issues and requested features. Some of the more commont issues are:
You get text like “G38G43G36G51G5” instead of what you expect when you are extracting text. This is because the characters are a meaningless internal encoding that point to glyphs that are embedded in the PDF document. The only way to access the text is to use OCR. This may be a future enhancement.
You get an error message like “java.io.IOException: Can't handle font width” this MIGHT be due to the fact that you don't have the org/apache/pdfbox/resources directory in your classpath. The easiest solution is to simply include the apache-pdfbox-x.x.x.jar in your classpath.
You get text that has the correct characters, but in the wrong order. This mght be because you have not enabled sorting. The text in PDF files is stored in chunks and the chunks do not need to be stored in the order that they are displayed on a page. By default, PDFBox does not sort the text.
