IronPDF - Introduction and Features

IronPDF is a Python library that helps to create PDF documents, and edit or manipulate any existing PDF files within Python applications.

It provides a simple yet powerful API to create PDF files with features like text formatting, images, tables, and more.

With IronPDF, developers can seamlessly integrate PDF functionality into their Python projects, making it an ideal choice for a wide range of applications, including reports, invoices, and documentation.

Najważniejsze cechy IronPDF:

• Easy Integration: IronPDF seamlessly integrates with popular Python development environments, making it accessible to developers using tools like PyCharm.
• Rich Text Support: It supports rich text formatting, allowing developers to create visually appealing PDF documents with ease.
• Image Handling: IronPDF enables the inclusion of images in PDFs, providing flexibility in designing and customizing documents.
• Cross-Platform Compatibility: IronPDF works across different platforms, ensuring that generated PDFs can be viewed and interacted with consistently.
• Document Settings: IronPDF offers robust document settings, empowering users to control PDF metadata, set permissions and passwords for enhanced security to generate encrypted PDF files, and seamlessly integrate digital signatures for document authenticity and integrity.

Wymagania wstępne

Before diving into the PDF generation process using IronPDF, ensure that you have the following prerequisites in place:

1. Python Installed: Python programming language needs to be installed on your system. You can download and install the latest version from the official Python website (https://www.python.org/).
2. PyCharm IDE: Use PyCharm or any other Python IDE of your choice. PyCharm is a popular integrated development environment that provides a comfortable workspace for Python development.
3. IronPDF: biblioteka IronPDF pobrana stąd lub zainstalowana za pomocą PIP (Python Package Manager). .NET runtime is also required to successfully use IronPDF functionality. Linux, Mac, and Windows users can download the .NET 6.0 version from here.

Create a Python Project in PyCharm

Po spełnieniu wymagań wstępnych otwórz PyCharm i utwórz nowy projekt w języku Python. Skonfiguruj środowisko wirtualne dla swojego projektu, aby efektywnie zarządzać zależnościami.

1. Kliknij Plik > Nowy projekt.
2. W oknie "Nowy projekt":
   • Enter a name for your project in the "Location" field.
   • Choose the location where you want to save your project files.
3. Under "Project Interpreter," select the Python interpreter you configured in Step 3.

4. Wybierz typ projektu. W przypadku prostego projektu w języku Python można pozostać przy ustawieniach domyślnych.

   

5. Click Create to create the project.

Install IronPDF for Python Using PIP

To install IronPDF, use the following PIP command in your project's terminal or command prompt:

pip install ironpdf

This command will automatically download and install the IronPDF library along with its dependencies.

Steps to Generate PDF in Python

Now that IronPDF is installed, we'll explore three common scenarios for PDF generation using IronPDF: from an HTML string, an HTML file, and a URL.

from ironpdf import ChromePdfRenderer

# Instantiate ChromePdfRenderer
renderer = ChromePdfRenderer()

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

# Export the PDF to a file
pdf.SaveAs("output_htmlstring.pdf")

from ironpdf import ChromePdfRenderer

# Instantiate ChromePdfRenderer
renderer = ChromePdfRenderer()

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

# Export the PDF to a file
pdf.SaveAs("output_htmlstring.pdf")

# Advanced Example with HTML Assets
# Load external HTML assets: Images, CSS, and JavaScript.
# An optional BasePath 'C:\\site\\assets\\' is set as the file location to load assets from
myAdvancedPdf = renderer.RenderHtmlAsPdf("<img src='icons/iron.png'>", r"C:\site\assets")
myAdvancedPdf.SaveAs("html-with-assets.pdf")

# Advanced Example with HTML Assets
# Load external HTML assets: Images, CSS, and JavaScript.
# An optional BasePath 'C:\\site\\assets\\' is set as the file location to load assets from
myAdvancedPdf = renderer.RenderHtmlAsPdf("<img src='icons/iron.png'>", r"C:\site\assets")
myAdvancedPdf.SaveAs("html-with-assets.pdf")

from ironpdf import ChromePdfRenderer      

# Instantiate ChromePdfRenderer
renderer = ChromePdfRenderer()

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

# Export the PDF to a file
pdf.SaveAs("output_htmlfile.pdf")

from ironpdf import ChromePdfRenderer      

# Instantiate ChromePdfRenderer
renderer = ChromePdfRenderer()

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

# Export the PDF to a file
pdf.SaveAs("output_htmlfile.pdf")

from ironpdf import ChromePdfRenderer

# Instantiate ChromePdfRenderer
renderer = ChromePdfRenderer()

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

# Export the PDF to a file
pdf.SaveAs("output_url.pdf")

from ironpdf import ChromePdfRenderer

# Instantiate ChromePdfRenderer
renderer = ChromePdfRenderer()

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

# Export the PDF to a file
pdf.SaveAs("output_url.pdf")
