7.1.1 HTML String to PDF

from ironpdf import ChromePdfRenderer

# Instantiate Renderer
renderer = ChromePdfRenderer()

# Create a PDF from an HTML string using Python
pdf = renderer.RenderHtmlAsPdf("<h1>Hello World</h1>")

# Export to a file or Stream
pdf.SaveAs("output.pdf")

from ironpdf import ChromePdfRenderer

# Instantiate Renderer
renderer = ChromePdfRenderer()

# Create a PDF from an HTML string using Python
pdf = renderer.RenderHtmlAsPdf("<h1>Hello World</h1>")

# Export to a file or Stream
pdf.SaveAs("output.pdf")

Here is the output of the HTML string converted to PDF:

7.1.2 HTML Files to PDF

from ironpdf import ChromePdfRenderer

# Instantiate Renderer
renderer = ChromePdfRenderer()

# Create a PDF from an existing HTML file using Python
pdf = renderer.RenderHtmlFileAsPdf("example.html")

# Export to a file or Stream
pdf.SaveAs("output.pdf")

from ironpdf import ChromePdfRenderer

# Instantiate Renderer
renderer = ChromePdfRenderer()

# Create a PDF from an existing HTML file using Python
pdf = renderer.RenderHtmlFileAsPdf("example.html")

# Export to a file or Stream
pdf.SaveAs("output.pdf")

Here is the output of the HTML file converted to PDF:

7.1.3 HTML URL to PDF

from ironpdf import ChromePdfRenderer

# Instantiate Renderer
renderer = ChromePdfRenderer()

# Create a PDF from a URL or local file path
pdf = renderer.RenderUrlAsPdf("https://ironpdf.com/python")

pdf.SaveAs("url.pdf")

Now, we'll look to convert HTML string, file, and URL to PDF using the wkhtmltopdf and pdfkit packages. First, you need to set the PATH to wkhtmltopdf lib installation or manually add the configuration before the code:

config = pdfkit.configuration(wkhtmltopdf='PATH-to-WKHTMLTOPDF-EXECUTABLE-FILE')

config = pdfkit.configuration(wkhtmltopdf='PATH-to-WKHTMLTOPDF-EXECUTABLE-FILE')

7.2.1 HTML String to PDF

import pdfkit

# Configuration specifying the path to the wkhtmltopdf executable
config = pdfkit.configuration(wkhtmltopdf='PATH-to-WKHTMLTOPDF-EXECUTABLE-FILE')

# Create PDF from HTML string
pdfkit.from_string('<h1>Hello World!</h1>', 'out.pdf', configuration=config)

import pdfkit

# Configuration specifying the path to the wkhtmltopdf executable
config = pdfkit.configuration(wkhtmltopdf='PATH-to-WKHTMLTOPDF-EXECUTABLE-FILE')

# Create PDF from HTML string
pdfkit.from_string('<h1>Hello World!</h1>', 'out.pdf', configuration=config)

Here is the HTML string converted to PDF:

7.2.2 HTML Files to PDF

import pdfkit

# Configuration specifying the path to the wkhtmltopdf executable
config = pdfkit.configuration(wkhtmltopdf='PATH-to-WKHTMLTOPDF-EXECUTABLE-FILE')

# Create PDF from HTML file
pdfkit.from_file('example.html', 'index.pdf', configuration=config)

import pdfkit

# Configuration specifying the path to the wkhtmltopdf executable
config = pdfkit.configuration(wkhtmltopdf='PATH-to-WKHTMLTOPDF-EXECUTABLE-FILE')

# Create PDF from HTML file
pdfkit.from_file('example.html', 'index.pdf', configuration=config)

Here is the HTML file converted to PDF:

7.2.3 HTML URL to PDF

import pdfkit

# Configuration specifying the path to the wkhtmltopdf executable
config = pdfkit.configuration(wkhtmltopdf='PATH-to-WKHTMLTOPDF-EXECUTABLE-FILE')

# Create PDF from URL
pdfkit.from_url('https://google.com', 'example.pdf', configuration=config)

import pdfkit

# Configuration specifying the path to the wkhtmltopdf executable
config = pdfkit.configuration(wkhtmltopdf='PATH-to-WKHTMLTOPDF-EXECUTABLE-FILE')

# Create PDF from URL
pdfkit.from_url('https://google.com', 'example.pdf', configuration=config)

In an overall comparison of the codes above and the functionalities both libraries provide, here is a detailed comparison of the code and features they provide for PDF generation:

1. Ease of Use

IronPDF provides a concise and Pythonic API, making it straightforward to use for HTML-to-PDF conversion. The code is clean and expressive.

wkhtmltopdf is simple and easy to use, but the syntax may be less Pythonic compared to IronPDF. Moreover, it is primarily a command-line tool and is dependent on another Python package to run wkhtmltopdf successfully in a Python environment.

2. Flexibility

IronPDF offers a high degree of flexibility with extensive customization options for rendering, editing, and securing PDFs. Here is a code example where you can create optional arguments as HTML Rendering Settings:

from ironpdf import ChromePdfRenderer

# Instantiate Renderer
renderer = ChromePdfRenderer()

# Many rendering options to use to customize!
renderer.RenderingOptions.SetCustomPaperSizeInInches(12.5, 20)
renderer.RenderingOptions.PrintHtmlBackgrounds = True
renderer.RenderingOptions.PaperOrientation = PdfPaperOrientation.Landscape
renderer.RenderingOptions.Title = "My PDF Document Name"
renderer.RenderingOptions.EnableJavaScript = True
renderer.RenderingOptions.WaitFor.RenderDelay(50)  # in milliseconds
renderer.RenderingOptions.CssMediaType = PdfCssMediaType.Screen
renderer.RenderingOptions.FitToPaperMode = FitToPaperModes.Zoom
renderer.RenderingOptions.Zoom = 100
renderer.RenderingOptions.CreatePdfFormsFromHtml = True

# Supports margin customization!
renderer.RenderingOptions.MarginTop = 40  # millimeters
renderer.RenderingOptions.MarginLeft = 20  # millimeters
renderer.RenderingOptions.MarginRight = 20  # millimeters
renderer.RenderingOptions.MarginBottom = 40  # millimeters

# Can set FirstPageNumber if you have a cover page
renderer.RenderingOptions.FirstPageNumber = 1  # use 2 if a cover page will be appended

# Settings have been set, we can render:
renderer.RenderUrlAsPdf("https://www.wikipedia.org/").SaveAs("my-content.pdf")

from ironpdf import ChromePdfRenderer

# Instantiate Renderer
renderer = ChromePdfRenderer()

# Many rendering options to use to customize!
renderer.RenderingOptions.SetCustomPaperSizeInInches(12.5, 20)
renderer.RenderingOptions.PrintHtmlBackgrounds = True
renderer.RenderingOptions.PaperOrientation = PdfPaperOrientation.Landscape
renderer.RenderingOptions.Title = "My PDF Document Name"
renderer.RenderingOptions.EnableJavaScript = True
renderer.RenderingOptions.WaitFor.RenderDelay(50)  # in milliseconds
renderer.RenderingOptions.CssMediaType = PdfCssMediaType.Screen
renderer.RenderingOptions.FitToPaperMode = FitToPaperModes.Zoom
renderer.RenderingOptions.Zoom = 100
renderer.RenderingOptions.CreatePdfFormsFromHtml = True

# Supports margin customization!
renderer.RenderingOptions.MarginTop = 40  # millimeters
renderer.RenderingOptions.MarginLeft = 20  # millimeters
renderer.RenderingOptions.MarginRight = 20  # millimeters
renderer.RenderingOptions.MarginBottom = 40  # millimeters

# Can set FirstPageNumber if you have a cover page
renderer.RenderingOptions.FirstPageNumber = 1  # use 2 if a cover page will be appended

# Settings have been set, we can render:
renderer.RenderUrlAsPdf("https://www.wikipedia.org/").SaveAs("my-content.pdf")

    'margin-right': '0.75in',
    'margin-bottom': '0.75in',
    'margin-left': '0.75in',
    'encoding': "UTF-8",
    'custom-header': [
        ('Accept-Encoding', 'gzip')
    ],
    'no-outline': None
}

pdfkit.from_file('index.html', 'index.pdf', options=options)

import pdfkit

options = {
    'page-size': 'Letter',
    'orientation': 'Landscape',
    'margin-top': '0.75in',
    'margin-right': '0.75in',
    'margin-bottom': '0.75in',
    'margin-left': '0.75in',
    'encoding': "UTF-8",
    'custom-header': [
