You can use Spire.PDF to read the image resolution from pdf. Dim pdf As PdfDocument = New PdfDocument() pdf.LoadFromFile( "input.pdf" ) Dim page As PdfPageBase = pdf.Pages(0) Dim horizontalResolution As Single = page.ImagesInfo(0).Image.HorizontalResolution Dim verticalResolution As Single = page.ImagesInfo(0).Image.VerticalResolution
