Convert DJVU to PDF via Java
Transform DJVU into PDF using native Java APIs without needing any image editor or 3rd-party libraries.
How to Convert DJVU to PDF Using Java
Converting file formats may seem like a routine task encountered by graphic designers. Yet, underestimating its significance would be a mistake. The evaluation of your work might depend on how swiftly and effectively you tackle this task. Typically, original images need conversion into formats better suited for printing or online publication. If the original image originates from a graphic editor, it might be in vector format. In this scenario, it must be rasterized and converted to a raster format for publishing purposes. You have the choice to save the image in an uncompressed format for optimal quality or convert it to a lossless compressed format to reduce file size. In certain contexts, like web publishing, you can opt for lossy compressed formats. Specially designed algorithms for image data compression permit a significant reduction in file size while preserving acceptable image quality. This facilitates fast image file downloads from the internet. In order to convert DJVU to PDF, we’ll use Aspose.Imaging for Java API which is a feature-rich, powerful and easy to use image manipulation and conversion API for Java platform. You can download its latest version directly from Maven and install it within your Maven-based project by adding the following configurations to the pom.xml.
<name>Aspose Java API</name>
<version>version of aspose-imaging API</version>
Steps to Convert DJVU to PDF via Java
Developers can easily load & convert DJVU files to PDF in just a few lines of code.
- Load DJVU file with Image.load method
- Create & set the instance of required subclass of ImageOptionsBase (e.g. BmpOptions, PngOptions, etc.)
- Call the Image.save method
- Pass file path with PDF extension & object of ImageOptionsBase class
Before running the conversion example code, make sure that you have the following prerequisites:
- JDK 1.6 or higher is installed.

DJVU What is DJVU File Format
DjVu, pronounced as “déjà vu”, is a graphics file format intended for scanned documents and books especially those which contain the combination of text, drawings, images and photographs. It was developed by AT&T Labs. It uses multiple techniques like image layer separation of text and background images, progressive loading, arithmetic coding and lossy compression for bitonal images. Since DJVU file can contain compressed yet high-quality colour images, photographs, text, and drawings and can be saved in less space therefore, it's used on web as eBooks, manuals, newspapers, ancient documents, etc.Read More | DJVU
PDF What is PDF File Format
Portable Document Format (PDF) is a type of document created by Adobe back in 1990s. The purpose of this file format was to introduce a standard for representation of documents and other reference material in a format that is independent of application software, hardware as well as Operating System. The PDF file format has full capability to contain information like text, images, hyperlinks, form-fields, rich media, digital signatures, attachments, metadata, Geospatial features and 3D objects in it that can become as part of source document.Read More | PDF
