Converting tif to pdf

Hi There,

I am using the following code snippet to convert a tif file to pdf. The original tif file size is around 40 KB whereas the pdf file size is close to 2 MB. This happens for other tif files too. Another sample I tried, the tif file is 3 MB and pdf is 51 MB. Please let me know why the pdf file size is so huge and how to reduce it. I am using Aspose PDF 19.2 for Java version for this conversion.

Document doc = new Document();
// Add a page to pages collection of document
Page page = doc.getPages().add();
// Load the source image file to Stream object
FileInputStream fs = new FileInputStream(“35860007_0001.0002.TIF”);

java.awt.image.BufferedImage bImage = null;
bImage = javax.imageio.ImageIO.read(new File(“12-1735-0616-8-003.TIF”));

	// Set margins so image will fit, etc.

Image image1 = new Image();
// Add the image into paragraphs collection of the section
// Set the image file stream


Find attached the tif file and the output pdf file for your reference.
