Hi Anneliese,
Thank you for contacting Syncfusion support.
We can find the file type using file extension from URL, based on the extension we can convert it to PDF and we can append to existing/new PDF document. If you could not find the file type from extension, then you find the file type or format using mime type from the URL or byte content.
Please refer below links for more information about the conversion,
