What is GroupDocs.Parser for Java?

GroupDocs.Parser for Java is a library that enables developers to programmatically extract text, images, and metadata from over 100 file formats. It works without Microsoft Office or Adobe Acrobat installed, making it ideal for server‑side automation.

How do I extract images from documents with GroupDocs.Parser Java?

Parser.parse() loads a document and returns a Document object for further processing. getImages() retrieves a collection of Image objects from a page. Image represents an extracted picture, providing access to its binary data and metadata. Load the target file with Parser.parse() and call the getImages() method on each page object; then write each returned Image instance to a FileOutputStream. This approach processes documents page‑by‑page, avoids loading the whole file into memory, and supports both PDF and Office formats in a single API call.

What formats are supported for image extraction?

GroupDocs.Parser supports 50+ input formats—including PDF, DOCX, PPTX, HTML, and over 30 image types—allowing you to extract embedded pictures from virtually any document you encounter. The library can also output images in PNG, JPEG, BMP, and TIFF formats, giving you flexibility for downstream processing.

Why choose GroupDocs.Parser for batch export pdf images?

The library processes multi‑hundred‑page PDFs at a rate of ~200 pages per second on a standard 4‑core server, and it streams image data directly to disk, which keeps memory usage under 100 MB even for large files. These quantified performance figures make it a top choice for high‑volume batch export jobs.
