Convert PDF files to images with PDFBox

Question

Can someone give me an example on how to use Apache PDFBox to convert a PDF file in different images (one for each page of the PDF)?

Accepted Answer

Solution for 1.8.* versions:

```
PDDocument document = PDDocument.loadNonSeq(new File(pdfFilename), null);
List<PDPage> pdPages = document.getDocumentCatalog().getAllPages();
int page = 0;
for (PDPage pdPage : pdPages)
{ 
    ++page;
    BufferedImage bim = pdPage.convertToImage(BufferedImage.TYPE_INT_RGB, 300);
    ImageIOUtil.writeImage(bim, pdfFilename + "-" + page + ".png", 300);
}
document.close();
```

Don't forget to read the 1.8 dependencies page before doing your build.

Solution for the 2.0 version:

```
PDDocument document = PDDocument.load(new File(pdfFilename));
PDFRenderer pdfRenderer = new PDFRenderer(document);
for (int page = 0; page < document.getNumberOfPages(); ++page)
{ 
    BufferedImage bim = pdfRenderer.renderImageWithDPI(page, 300, ImageType.RGB);

// suffix in filename will be used as the file format
    ImageIOUtil.writeImage(bim, pdfFilename + "-" + (page+1) + ".png", 300);
}
document.close();
```

Solution for the 3.0 versions:

```
PDDocument document = Loader.loadPDF(new File(pdfFilename));
```

(the rest is like in 2.0)

The ImageIOUtil class is in a separate download / artifact (pdf-tools). Read the 2.0 dependencies page before doing your build, you'll need extra jar files for PDFs with jbig2 images, for saving to tiff images, and reading of encrypted files.

Make sure you have logging enabled and are using the latest version of whatever JDK version prefer, i.e. if you are using jdk8, then don't use version 1.8.0_5, use 1.8.0_391 or whatever is the latest at the time you're reading this text. Early jdk versions were very slow.
