Aspose.PDF for Java allows converting PDF to any of different supported formats like Word, HTML, PowerPoint, etc within Java applications is easy with just a few lines of code.
// load the document Document pdoc = new Document(dir + "template.pdf"); // Convert to DOCX, HTML and PPTX pdoc.save(dir + "output.docx", SaveFormat.DocX); pdoc.save(dir + "output.pptx", SaveFormat.Pptx); pdoc.save(dir + "output.html", SaveFormat.Html);
Aspose.PDF for Java API not only creates files from scratch but also manipulates and saves documents to multiple formats including PDF/A compliant documents. Moreover, API also supports PDF generation from XML, PCL or image files.
Few of the files manipulation capabilities of API are table creation, specifying the table width, margin information, padding, row span, column-span, default cell text and much more. Nested tables, as well as the integration of tables with data sources, also supported.
Java PDF library has the ability to align text horizontally as well as vertically. Within horizontal alignment, one can easily change content alignment from left to right with respect to languages such as Arabic, Hebrew, and Urdu and can handle white spaces in the text, set custom tab stops and much more. For vertical alignment, one can adjust text segments such as baseline or topline.
Furthermore, API supports defining text formatting for all segments of a document, changing text foreground and background colors and usage of replaceable symbols which allows changing the corresponding text content at runtime.
API offers the facility to encrypt documents with a verity of encryption algorithms and key sizes. One can also set user and master passwords for more security. Content manipulation like copying, printing, form field completion, annotation modification, degraded printing as well as PDF files assembly can all be restricted via this library.
// load file to be encrypted Document pfile = new Document(dir + "template.pdf"); // encrypt the document pfile.encrypt("userPassword", "ownerPassword", 0, CryptoAlgorithm.AESx256); // save the encrypted one pfile.save(dir + "output.pdf");
Aspose.PDF for Java supports graphs, drawn on any page by specifying coordinates. You may also choose to rotate or scale the existing graphs to suit your requirements.
API allows images insertion, replacement, and deletion, present within files as well as enables to use images as watermark while creating files or manipulating existing documents.
Beyond simple form fields processing like addition & removal of form fields, the library provides advanced features such as converting Dynamic XFA form to Standard AcroForm, getting form fields from a specific region of PDF document, adding tooltips and setting custom fonts for the form fields.
Aspose.PDF for Java APIs are built using managed code that can be installed and deployed without needing Adobe Acrobat installed. It is easier and flexible to use as compared to Adobe Acrobat automation.

The initial benefit was a reduction in licensing fees as Office no longer needed to be installed on each provided server. In addition to those immediate savings we saw an additional benefit in being able to programmatically lock and sign the PDF documents.Paul Allaire | Loryx Systems, USA
