Add Barcodes in HTML to PDF

Python developers can add barcodes to their PDF documents with IronPDF for Python in two ways, as illustrated above:

Method 1: Add Barcodes Using the ChromePdfRenderer

Use this method to create barcodes that contain text-based information:

1. Create a string variable that holds the following HTML elements:
   • A link element that references a barcode web font like this one.
   • An element containing the text that you want encoded in a barcode.
2. Create a new ChromePdfRenderer object.
3. Call the RenderHtmlAsPdf method on the new object with the string variable as the argument.
4. Save the resulting PdfDocument object to a file.

Method 2: Add Barcodes Using the BarcodeStamper

Use this approach when you want more control over how the barcode appears (e.g., width, height, page positioning, etc.):

1. Create a PdfDocument object, as shown below.

   from ironpdf import PdfDocument, ChromePdfRenderer
   
   # Create from existing PDF file on the file system
   existing_pdf = PdfDocument("existing.pdf")
   
   # Create from HTML using ChromePdfRenderer
   new_pdf = ChromePdfRenderer().render_html_as_pdf("<h1>Hello world!</h1>")

   from ironpdf import PdfDocument, ChromePdfRenderer
   
   # Create from existing PDF file on the file system
   existing_pdf = PdfDocument("existing.pdf")
   
   # Create from HTML using ChromePdfRenderer
   new_pdf = ChromePdfRenderer().render_html_as_pdf("<h1>Hello world!</h1>")

   PYTHON
2. Create a BarcodeStamper object, specifying the text to encode along with a target Barcode Format in the parameter list (width and height are optional).
3. Call the apply_stamp method on the PdfDocument object.
4. Save the changes.

Use the IronBarcode C# Library for even more control over barcode creation. (And then stamp them onto your PDFs using IronPDF for Python's HtmlStamper!)

• Note: For the Python example above, replace ChromePdfRenderer() and method names with the correct Python library methods and initialize them appropriately based on the imports at the top of the code block.
