Java developers can easily load & merge PDF files to JPEG in just a few lines of code.
- Initialize a new Document, and run a loop for merging files
- In loop: add a new page to JPEG document
- In loop: add PDF file to new page
- After the loop save the result
Here is an example that demonstrates how to merge PDF to JPEG in Java. Combine multiple documents into a single file with ease. If you are developing code in Java, this task can be simpler than it sounds. You can use fully qualified filenames for both PDF reading and JPEG writing. Check out this Java example that show how to merge multiple documents of either the same or different file types into one file using Java
Merge PDF files using Java and save as JPEG
Example Java: this sample code shows PDF to JPEG concatenation
Input file:
File not added
File not added
Output format:
Output file:
String inputFile1 = DATA_DIR.resolve("1.pdf").toString();
String inputFile2 = DATA_DIR.resolve("2.pdf").toString();
String outputFilePattern = DATA_DIR.resolve("merger_pdf_jpeg_%d.jpg").toString();
// Load documents
Document pdfDocument1 = new Document(inputFile1);
Document pdfDocument2 = new Document(inputFile2);
// Merge documents
pdfDocument1.getPages().add(pdfDocument2.getPages());
// Convert pages to JPEG
for (int i = 1; i <= pdfDocument1.getPages().size(); i++) {
JpegDevice image = new JpegDevice();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
image.process(pdfDocument1.getPages().get_Item(i), stream);
try (FileOutputStream fileStream = new FileOutputStream(String.format(outputFilePattern, i))) {
stream.writeTo(fileStream);
} catch (Exception e) {
System.err.println(e.getMessage());
}
}
// Close documents
pdfDocument1.close();
pdfDocument2.close();
