  2. Upload your PDF file to inspect its embedded catalog tree.
  3. Click Extract next to any embedded file (e.g. `factur-x.xml`) to download it instantly.
  4. To attach new files, click Select Files to Embed and choose XML, CSV, XLSX, or image files.
  5. Click Embed & Save PDF to download your updated multi-file container.
