title: How to convert Image to PDF?
body: <p>I am developing an application where I need to convert an Image to PDF. I tried something, but the issue is, Image size in that PDF is very very small. I need solution to fix this. Also I am looking for converting multiple Images into single PDF document. 
  I will post the code which I tried. </p>
  
  <pre><code>    public void convertPDF(byte[] path)
  {
   String FILE = "mnt/sdcard/FirstPdf.pdf";
      Document document=new Document();
      try {
          PdfWriter.getInstance(document, new FileOutputStream(FILE));
          document.open();
  
          try {
              image=Image.getInstance(path);
              document.add(new Paragraph("My Heading"));
              document.add(image);
              document.close();
          } catch (IOException e) {
              e.printStackTrace();
          }
      } catch (DocumentException e) {
          e.printStackTrace();
      } catch (FileNotFoundException e) {
          e.printStackTrace();
      }
  }
  </code></pre>
  
  <p>When I convert Bitmap to Byte array, I am compressing the image and I guess, that's the reason. Without compressing the image, I am unable to convert Bitmap to Byte Array.</p>
  
  <pre><code> ByteArrayOutputStream stream = new ByteArrayOutputStream();
          bmp.compress(Bitmap.CompressFormat.PNG,100,stream);
          byte[] byteArray=stream.toByteArray();
          convertPDF(byteArray);
  </code></pre>
  
  <p>Is there any solution for this? </p>

  <p>Here I have implemented the answer which suggested by @Burak Cakir in the answer. But now I am getting larger image in PDF.
