Hello,
you are not missing anything: PDF24 Creator has no word processor of its own. It creates PDFs from existing documents. "Create blank document" in PDF24 Creator only creates an empty document into which you can drag pages from other files.
To write a new document from scratch, you have two options:
- Write it in any program that can print, for example Word, LibreOffice Writer or Notepad, and print it on the printer "PDF24". The PDF24 Assistant then opens, and you can save the PDF.
- Use the online tool "Write PDF". You write there like in a word processor, with headings, tables and pictures, and then create a PDF: https://tools.pdf24.org/en/write-pdf
