Convert PDF to Image Formats in Go

Go Convert PDF to Image

This article explains how to render PDF pages to several raster and vector image formats with Aspose.PDF for Go via C++.

Previously scanned documents are often stored as PDF files, but many workflows require those pages as standalone images for previews, archives, medical systems, reporting pipelines, or graphic editing. Aspose.PDF for Go via C++ lets you open a PDF document, render a specific page, and save that page in the output format required by your application.

The most common scenario is exporting one page or several pages from a PDF as a set of images. Depending on the target format, you can choose a method such as PageToJpg, PageToPng, PageToTiff, PageToBmp, PageToSvg, or PageToDICOM to generate the output file directly from the opened PDF document.

Aspose.PDF for Go via C++ supports several PDF-to-image conversion workflows. For the broader list of supported formats, see Aspose.PDF Supported File Formats.

Convert PDF to JPEG

The following example shows how to convert the first page of a PDF document to a JPEG image. Use this method when you need a widely supported raster format for web previews, image processing, or lightweight sharing.

Use the Open method to load the source PDF file and return a Document instance for further processing.
Call the PageToJpg method to render page 1 at the requested DPI value and save the result as a JPEG image file.
Use the Close method after conversion to release the resources associated with the opened PDF document.


    package main

    import "github.com/aspose-pdf/aspose-pdf-go-cpp"
    import "log"

    func main() {
      // Open(filename string) opens a PDF-document with filename
      pdf, err := asposepdf.Open("sample.pdf")
      if err != nil {
        log.Fatal(err)
      }
      // Close() releases allocated resources for PDF-document
      defer pdf.Close()
      // PageToJpg(num int32, resolution_dpi int32, filename string) saves the specified page as Jpg-image file
      err = pdf.PageToJpg(1, 100, "sample_page1.jpg")
      if err != nil {
        log.Fatal(err)
      }
    }

Convert PDF to TIFF

The following example shows how to convert the first page of a PDF document to a TIFF image. Use this method for high-fidelity page rendering, archival image workflows, or downstream systems that prefer TIFF output.

Use the Open method to load the source PDF document from disk.
Call the PageToTiff method to render the selected page at the specified DPI and save it as a TIFF image.
Use the Close method to free the native PDF resources when processing is finished.


    package main

    import "github.com/aspose-pdf/aspose-pdf-go-cpp"
    import "log"

    func main() {
      // Open(filename string) opens a PDF-document with filename
      pdf, err := asposepdf.Open("sample.pdf")
      if err != nil {
        log.Fatal(err)
      }
      // Close() releases allocated resources for PDF-document
      defer pdf.Close()
      // PageToTiff(num int32, resolution_dpi int32, filename string) saves the specified page as Tiff-image file
      err = pdf.PageToTiff(1, 100, "sample_page1.tiff")
      if err != nil {
        log.Fatal(err)
      }
    }

Convert PDF to PNG

The following example shows how to convert the first page of a PDF document to a PNG image. Use this method when you need lossless output for screenshots, UI assets, or document previews with crisp text and graphics.

Use the Open method to open the input PDF file.
Call the PageToPng method to render the chosen page to a PNG file at the requested resolution.
Use the Close method after conversion to release the Document resources.


    package main

    import "github.com/aspose-pdf/aspose-pdf-go-cpp"
    import "log"

    func main() {
      // Open(filename string) opens a PDF-document with filename
      pdf, err := asposepdf.Open("sample.pdf")
      if err != nil {
        log.Fatal(err)
      }
      // Close() releases allocated resources for PDF-document
      defer pdf.Close()
      // PageToPng(num int32, resolution_dpi int32, filename string) saves the specified page as Png-image file
      err = pdf.PageToPng(1, 100, "sample_page1.png")
      if err != nil {
        log.Fatal(err)
      }
    }

Scalable Vector Graphics (SVG) is a family of specifications of an XML-based file format for two-dimensional vector graphics, both static and dynamic (interactive or animated). The SVG specification is an open standard that has been under development by the World Wide Web Consortium (W3C) since 1999.

Convert PDF to SVG

The following example shows how to convert the first page of a PDF document to an SVG image. Use this method when you need a scalable vector result that preserves geometry and remains sharp at different zoom levels.

Use the Open method to load the input PDF document.
Call the PageToSvg method to export the specified page as an SVG file.
Use the Close method when the conversion is complete to release the document resources.


    package main

    import "github.com/aspose-pdf/aspose-pdf-go-cpp"
    import "log"

    func main() {
      // Open(filename string) opens a PDF-document with filename
      pdf, err := asposepdf.Open("sample.pdf")
      if err != nil {
        log.Fatal(err)
      }
      // Close() releases allocated resources for PDF-document
      defer pdf.Close()
      // PageToSvg(num int32, filename string) saves the specified page as Svg-image file
      err = pdf.PageToSvg(1, "sample_page1.svg")
      if err != nil {
        log.Fatal(err)
      }
    }

Convert PDF to DICOM

The following example shows how to convert the first page of a PDF document to a DICOM image. Use this method for workflows that exchange image data with medical or imaging systems that require DICOM-compatible output.

Use the Open method to load the source PDF document into a Document object.
Call the PageToDICOM method to render the selected page at the requested DPI and save it as a DICOM image file.
Use the Close method after conversion to release the allocated PDF resources.


    package main

    import "github.com/aspose-pdf/aspose-pdf-go-cpp"
    import "log"

    func main() {
      // Open(filename string) opens a PDF-document with filename
      pdf, err := asposepdf.Open("sample.pdf")
      if err != nil {
        log.Fatal(err)
      }
      // Close() releases allocated resources for PDF-document
      defer pdf.Close()
      // PageToDICOM(num int32, resolution_dpi int32, filename string) saves the specified page as DICOM-image file
      err = pdf.PageToDICOM(1, 100, "sample_page1.dcm")
      if err != nil {
        log.Fatal(err)
      }
    }

Convert PDF to BMP

The following example shows how to convert the first page of a PDF document to a BMP image. Use this method when you need an uncompressed raster output for basic desktop processing or compatibility with legacy image workflows.

Use the Open method to load the source PDF file.
Call the PageToBmp method to render the required page at the specified DPI and save it as a BMP image.
Use the Close method to release the PDF resources after the image file has been written.


    package main
