title: Merge two PDF pages into new one without blank spaces between text content
body: <p>all</p>
  
  <p>I want to merge two PDFs as one PDF. In the meantime I would like to join these two PDFs seamlessly. </p>
  
  <p>For example, say the last page of the first PDF file have quite a lot of empty spaces, after merging, I would hope that the second PDF will start from the blank spaces of the first PDF.</p>
  
  <p>Do we have any tool supporting that?</p>
