Pdfreader accepts System.IO.MemoryStream , or any generic System.IO.Stream , as can be seen in the API documentation: https://api.itextpdf.com/iText7/dotnet/7.1.11/classi_text_1_1_kernel_1_1_pdf_1_1_pdf_reader.html

PdfReader (IRandomAccessSource byteSource, ReaderProperties properties)
Constructs a new PdfReader. More...

PdfReader (Stream @is, ReaderProperties properties)
Reads and parses a PDF document. More...

PdfReader (FileInfo file)
Reads and parses a PDF document. More...

PdfReader (Stream @is)
Reads and parses a PDF document. More...

PdfReader (String filename, ReaderProperties properties)

PdfReader (String filename)

So you can pass the data from the IFormFile form.
