Merge SVG to PDF in C#

SVG is one of the most used formats for website building and print graphics to achieve scalability. But sometimes, you need to merge SVG files and save them as one document in another file format. PDF is a file format supported by all operating systems and used for presenting images, documents and books. Files in PDF can be easily viewed, printed, and shared online. With Aspose.SVG for .NET API, you can merge SVG to PDF programmatically. Powerful C# API helps you to combine SVG files quickly and in high quality.

C# code example to merge SVG to PDF

A high-speed C# library allows .NET developers to merge SVG files and convert the combined result into other popular formats such as PDF, XPS, JPEG, PNG, BMP, GIF, and TIFF quickly and efficiently. You can combine multiple SVG files into a single file of another format at the same time and improve performance for tasks such as resource management, optimizing the number of HTTP requests, reducing the loading time of web applications, etc. Documents merging can be done with a few lines of code:

Merge SVG to PDF – C#

// Initialize SVG documents from files to merge
using (var document1 = new SVGDocument("document1.svg"))
using (var document2 = new SVGDocument("document2.svg"))
using (var document3 = new SVGDocument("document3.svg"))
    // Create an instance of SvgRenderer
    using var renderer = new Aspose.Svg.Rendering.SvgRenderer();
    // Create an instance of PdfDevice
    using var device = new Aspose.Svg.Rendering.Pdf.PdfDevice("result.pdf");
    // Merge SVG to PDF
    renderer.Render(device, document1, document2, document3);

Steps to Merge SVG to PDF using C#

  1. Load SVG documents using one of the SVGDocument() constructors.
  2. Create a new instance of the SvgRenderer class.
  3. Use the PdfDevice() constructor to initialize a new instance of the PdfDevice class.
  4. Call the Render() method to merge several SVGs to PDF file.
  5. Multiple SVG files will be saved into one PDF document at the specified path.

In the C# example above, the output format is PDF, as indicated by the use of PdfDevice. If you want to change the output format, you will need to use a different device class that matches the desired format. For example, you can use ImageDevice for PNG, JPEG, BMP, GIF, or TIFF formats. Additionally, you will need to provide the appropriate file extension in the output file path.
