Usage Java to convert PDF version to 1.4 for FPDI PDF-Parser (free license) without Ghostscript

PDFConvert14

Introduction

By default FPDI can "only" handle PDF documents up to PDF version 1.4. Beginning with PDF version 1.5 there were new compression features introduced which involve internal structure changes how a PDF document can be created.

With this seperate parser, as a commercial addon, you're up to date and FPDI will be able to handle PDF documents with a version higher than 1.4 without problems. [More Information](https://www.setasign.com/products/fpdi-pdf-parser/details/)
