I am trying to create a pdf using AcmBlock manually using AcmRender and the sending it as a response .
Even if i create a empty pdf. the size of pdf is too large eg 5mb in my case

Here is my code
PdfDocument pdf = new PdfDocument();

AcmRender acmRender = new AcmRender(pdf, new AcmPageLayout(new AcmPadding(0)) );

AcmBlock content = new AcmBlock();
content.Style.Margin = new AcmPadding(0);
content.Style.Padding = new AcmPadding(0);

// block to add content commented for now
////



acmRender.Render(content);

Context.Response.Clear();
Context.Response.ContentType = "application/pdf";
Context.Response.Charset = "utf-8";
Context.Response.AddHeader("content-disposition", $"attachment;filename=abc.pdf");

pdf.Save(Context.Response.OutputStream);


Can you please tell my what's wrong with this and why the size is to large
