How to Generate PDF File in F# Library
- Download the F# PDF Library
- Create a PDF document with F# Library
- Customize your PDF document styles
- Build templates for document creation in F#
- Edit your PDF files from F# Library
Install the F# PDF Library
Install via NuGet Package Manager
In Visual Studio, right-click on your project solution explorer and select "Manage NuGet Packages...". From there simply search for IronPDF and install the latest version. Click OK to any dialog boxes that come up. This will work in any .NET Project.
Install via NuGet Package Manager Console
You may also choose to add IronPDF through the package manager console which can be done with this command:
Install-Package IronPdf
Install Directly in the .fsproj
Another option is to paste the following ItemGroup into your .fsproj file:
<ItemGroup>
<PackageReference Include="IronPdf" Version="*" />
</ItemGroup><ItemGroup>
<PackageReference Include="IronPdf" Version="*" />
</ItemGroup>Install via DLL
Alternatively, the IronPDF DLL can be downloaded and manually installed to the project or GAC from https://ironpdf.com/packages/IronPdf.zip
Remember to add this statement to the top of any .fs class file using IronPDF:
open IronPdfopen IronPdfCreate a PDF from HTML with F
Begin by opening the IronPDF library within your namespace using open. After that, create a ChromePdfRenderer object and pass an HTML string into its RenderHtmlAsPdf method. If you already have an HTML file ready, you can pass the file path string as a parameter to RenderHtmlFileAsPdf.
HTML String to PDF in F
open IronPdf
let html = "<p>Hello World</p>"
// Initialize the PDF Renderer
let renderer = ChromePdfRenderer()
// Render HTML as PDF
let pdf = html |> renderer.RenderHtmlAsPdf
// Save the PDF document
pdf.SaveAs("document.pdf") |> ignoreopen IronPdf
let html = "<p>Hello World</p>"
// Initialize the PDF Renderer
let renderer = ChromePdfRenderer()
// Render HTML as PDF
let pdf = html |> renderer.RenderHtmlAsPdf
// Save the PDF document
pdf.SaveAs("document.pdf") |> ignoreHTML File to PDF in F
open IronPdf
let htmlFilePath = "C:/designs/html/layout.html"
// Initialize the PDF Renderer
let renderer = ChromePdfRenderer()
// Render HTML file as PDF
let pdf = htmlFilePath |> renderer.RenderHtmlFileAsPdf
// Save the PDF document

let htmlFilePath = "C:/designs/html/layout.html"
// Initialize the PDF Renderer
let renderer = ChromePdfRenderer()
// Render HTML file as PDF
let pdf = htmlFilePath |> renderer.RenderHtmlFileAsPdf
// Save the PDF document
pdf.SaveAs("document.pdf") |> ignoreAdvanced IronPDF F# Template
Here is a more advanced example of creating a function that will format and style a PDF from a URL based on some rules and procedures:
open IronPdf
let CreateCompanyStandardDocument (url : string) =
// Setup Render Options with desired settings
let renderOptions = ChromePdfRenderOptions(
CssMediaType = Rendering.PdfCssMediaType.Screen,
EnableJavaScript = true,
PrintHtmlBackgrounds = true,
InputEncoding = System.Text.Encoding.UTF8,
MarginTop = 0.39,
MarginBottom = 0.38,
MarginLeft = 0.39,
MarginRight = 0.38
)
// Create Header Template for the PDF
let companyStyleHeader = HtmlHeaderFooter()
companyStyleHeader.HtmlFragment <- "<img src='https://ironsoftware.com/img/svgs/ironsoftware-logo-black.svg'>"
companyStyleHeader.DrawDividerLine <- true
// Apply the header to the Render Options
renderOptions.HtmlHeader <- companyStyleHeader
// Initialize Renderer with customized options
let renderer = ChromePdfRenderer(RenderingOptions = renderOptions)
// Generate PDF from URL without additional styles
let htmlPdfWithoutStyle = url |> renderer.RenderUrlAsPdf
// Add the styled header to the PDF document
htmlPdfWithoutStyle.AddHtmlHeaders companyStyleHeader |> ignore
// Return the created PDF document
htmlPdfWithoutStyle
let IronPdfUrlToPdf (url : string) =
// Create a styled PDF document from the given URL
let pdf = url |> CreateCompanyStandardDocument
// Save the PDF document to the file system
pdf.SaveAs("document.pdf") |> ignore
// Set your IronPDF License Key
IronPdf.License.LicenseKey <- "YOUR_LICENSE_KEY_HERE"
// Example usage: Convert the given URL to a PDF document

let CreateCompanyStandardDocument (url : string) =

companyStyleHeader.DrawDividerLine <- true
// Apply the header to the Render Options
