<section class="about">
  <h2>Repeating a page without retyping or rescanning it</h2>
  <p>Duplicate Pages copies whichever pages you specify and inserts each copy immediately after its original, using pdf-lib's <code>copyPages</code> — useful for repeating a signature page, a cover, or a form across a longer document without rebuilding it from scratch. The page-number picker is the same range/list syntax as <a href="./delete-pages.html">Delete Pages</a>, so if you've used that one, this one will feel familiar.</p>
  <p>Because this grows the page count rather than shrinking or rearranging it, duplicating pages inside an already-large PDF (a hundred-plus pages, or pages full of scanned images) compounds the size the browser has to hold in memory. If a big source file makes the tab sluggish before you've even duplicated anything, <a href="./guide-large-file-freeze.html">this explains why, and how to keep it responsive</a>.</p>
