Text to PDF Converter

The TextToPDFConverter program is able to convert a text file to a PDF file. It is easy to use. When the program runs, it displays a file dialog that you can select one or multiple text files to convert. Click OK to accept the selection. The result PDF files are stored in your current working folder where you place the TextToPDFConverter program.

This program uses the iText library to create a PDF file from a text file. Each line of text in the text file is read by using the BufferedReader class of Java. The line of text is added to the Document object of iText. The PdfWriter writes the document to the PDF output file.
