In the article of convert PDF to SVG by Spire.PDF, each page on the PDF file has been saved as a single SVG file. For example, if the PDF contains 10 pages, we will get 10 SVG files separately. From version 2.7.6, Spire.PDF for Java supports to convert a multipage PDF to one single SVG file in Java.
import com.spire.pdf.*;
public class PDFtoSVG {
public static void main(String[] args) throws Exception {
String inputPath = "Sample.pdf";
PdfDocument document = new PdfDocument();
document.loadFromFile(inputPath);
document.getConvertOptions().setOutputToOneSvg(true);
document.saveToFile("output.svg", FileFormat.SVG);
document.close();
}
}
