SVG is a file format for vector graphics, used to create images that can be scaled without loss of quality. However, PDF is more suitable for sharing and printing due to its support for high-quality printing, encryption, digital signatures, and other features. Converting SVG to PDF ensures good image display on different devices and environments, and better protects intellectual property. In this tutorial, we will show you how to convert SVG to PDF and how to add a SVG image to PDF in C# and VB.NET using Spire.PDF for .NET.

namespace SVGtoPDF
{
class Program
{
static void Main(string[] args)
{
//Create a PdfDocument object
PdfDocument doc = new PdfDocument();
//Load a sample SVG file
doc.LoadFromSvg("Sample.svg");
//Save result document
doc.SaveToFile("Result.pdf", FileFormat.PDF);
doc.Dispose();
}
}
}
Add SVG image to PDF in C# and VB.NET
In addition to converting SVG to PDF directly, it also supports adding SVG image files to the specified locations in PDF. Please check the steps as below:
- Create a PdfDocument object and load an SVG file using PdfDocument. LoadFromSvg() method.
- Create a template based on the content of the SVG file using PdfDocument. Pages[].CreateTemplate() method.
- Get the width and height of the template on the page.
- Create another PdfDocument object and load a PDF file using PdfDocument.LoadFromFile() method.
- Draw the template with a custom size at a specified location using PdfDocument.Pages[].Canvas.DrawTemplate() method.
- Save to PDF file using PdfDocument.SaveToFile(String, FileFormat) method.
- C#
- VB.NET
using Spire.Pdf;
using Spire.Pdf.Graphics;
using System.Drawing;
namespace AddSVGImagetoPDF
{
class Program
{
static void Main(string[] args)
{
//Create a PdfDocument object
PdfDocument doc1 = new PdfDocument();
//Load an SVG file
doc1.LoadFromSvg("C:\\Users\\Administrator\\Desktop\\sample.svg");
//Create a template based on the content of the SVG file
PdfTemplate template = doc1.Pages[0].CreateTemplate();
//Get the width and height of the template
float width = template.Width;
float height = template.Height;
//Create another PdfDocument object
PdfDocument doc2 = new PdfDocument();
//Load a PDF file
doc2.LoadFromFile("C:\\Users\\Administrator\\Desktop\\sample.pdf");
//Draw the template with a custom size at a specified location
doc2.Pages[0].Canvas.DrawTemplate(template, new PointF(0, 0), new SizeF(width * 0.8f, height * 0.8f));
//Save to PDF file
doc2.SaveToFile("AddSvgToPdf.pdf", FileFormat.PDF);
doc2.Dispose();
}
}
