Break info multiple PDF based on file size

[colinmhart]

I see the examples that break into multiple PDF's by page numbers (i.e. 1-10, 11-20) but is there a way to check the file size and break into multiple files if the file is greater than say 10 Mb?

Hello,

Thanks for your inquiry.
For your requirement, you can refer to the following code.

    internal class Program

        static void Main(string[] args)
        {

            string filePath = @"C:\Users\Administrator\Desktop\8-29测试文件\Original.pdf";

            //load the pdf document
            PdfDocument pdf = new PdfDocument();
            pdf.LoadFromFile(filePath);

            //Get the file size of pdf document
            FileInfo fileInfo = new FileInfo(filePath);
            double filesize = fileInfo.Length / 1024.0/1024.0;
            if (filesize > 0.1)
            {
                String pattern = "SplitDocument-{0}.pdf";
                //Split document
                pdf.Split(pattern);

                pdf.Close();
            }
        }
    }
}

thanks for the reply. Can I add a bit more onto this
I need to make sure all the PDF's are less than 10MB
so if I 31MB file, I need Spire to break that into 4 files so each PDF is < 10 MB
the max would be 100MB, so how could I make it so that it would detect the file size and then break it the number of files needed to be < 10 MB per PDF?

Hello,

Thanks for your feedback.
For your requirement, you can split the entire document into multiple one-page documents and then merge the documents. For example, if the sum of document1’size and document2’size after splitting don’t more than 10mb, you can merge document1 and document2 into a new document, and so on.
For how to merge Pdf file, you can refer to the help document from the following link:
