Limits
- Each page is placed as a scaled copy: it keeps its look and text, but links, form fields and annotations on it are lost.
- Aspect ratio is kept, so pages with a different shape get margins instead of being stretched.
- Password-protected PDFs are refused (there is no password prompt yet); remove the password first.
- PDFs over 2,000 pages are refused to keep your browser responsive.
