How to generate pdf from word using Aspose.Words for Java?

Document is the Aspose.Words object that loads and represents a Word file. To generate a PDF, load an existing Word file with new Document("input.docx") and call doc.save("output.pdf", SaveFormat.PDF). Aspose.Words automatically preserves fonts, tables, images, and complex layouts, delivering a PDF that looks identical to the source document while handling large files efficiently.

How to convert word to pdf java?

Document loads a Word file and provides conversion methods. To convert Word to PDF in Java, open the document with new Document("input.docx") and invoke doc.save("output.pdf", SaveFormat.PDF). For batch conversion, iterate through a folder of .docx files, loading each into a Document and saving as PDF. No external converters or Office installations are required.

How to extract text word java?

Document represents the loaded Word file and provides methods to access its content. To extract plain text, create a Document object with the source file and call doc.getText(), which returns the document’s text without any formatting. The resulting string can be indexed, searched, or fed into NLP pipelines for further processing.
