Why Export PDF as HTML?

HTML (HyperText Markup Language) is the foundation of web content. By exporting PDFs into HTML, you enable seamless viewing, editing, and indexing of document content online. Key advantages include:

• Improved Web Accessibility: HTML renders natively in all browsers.
• Search Engine Optimization (SEO): Search engines can index content better than in PDFs.
• Responsive Layouts: HTML adjusts to different screen sizes.
• Interactive Enhancements: HTML allows for styling, scripts, and better user interaction.
• Plugin-Free Viewing: No need for third-party PDF viewers.

Install Python PDF to HTML Converter Library

To start exporting PDFs to HTML using Python, you’ll need a reliable library that supports PDF processing and HTML export. For this tutorial, we’re using Spire.PDF for Python, a high-performance PDF library that supports reading, editing, and converting PDF files in various formats, including HTML, with minimal effort.

Installation

The library can be installed easily via pip. Open your terminal and run the following command:

pip install Spire.PDF

This will download and install the latest version of the package along with its dependencies.

Basic PDF to HTML Conversion in Python

Spire.PDF makes it easy to export an entire PDF document to HTML using the SaveToFile() method.

from spire.pdf.common import *
from spire.pdf import *

# Initialize a PdfDocument object
doc = PdfDocument()

# Load your PDF file
doc.LoadFromFile("Sample.pdf")

# Convert and save it as HTML
doc.SaveToFile("PdfToHtml.html", FileFormat.HTML)

# Close the document
doc.Close()

This approach generates a single HTML file that preserves the layout and structure of the original PDF.

The screenshot below showcases the input PDF and the output HTML file:

Customize the HTML Output

If you need more control over the conversion process, the SetPdfToHtmlOptions() method lets you fine-tune the HTML output.

You can customize various aspects of the conversion—such as image embedding, page splitting, and SVG quality—using the following parameters:

Example Code

from spire.pdf.common import *
from spire.pdf import *

# Initialize a PdfDocument object
doc = PdfDocument()
# Load your PDF file
doc.LoadFromFile("Sample.pdf")

# Access conversion settings
options = doc.ConvertOptions

# Customize conversion: use image embedding, one page per file
options.SetPdfToHtmlOptions(False, True, 1, False)

# Save the PDF to HTML with the custom options
doc.SaveToFile("PdfToHtmlWithOptions.html", FileFormat.HTML)
# Close the document
doc.Close()

This configuration disables SVG and instead embeds images, outputting each page as a separate HTML file.

Save PDF to HTML Stream

In web or cloud-based applications, you might prefer to write the HTML output to a stream (e.g., for serving over HTTP) instead of saving directly to the file system. This can be achieved with the SaveToStream() method.

Example Code

from spire.pdf.common import *
from spire.pdf import *

# Initialize a PdfDocument object
doc = PdfDocument()
# Load your PDF file
doc.LoadFromFile("Sample.pdf")

# Create a stream to save the HTML output
fileStream = Stream("PdfToHtmlStream.html")

# Save the PDF to HTML stream
doc.SaveToStream(fileStream, FileFormat.HTML)

# Close the stream and the document
fileStream.Close()
doc.Close()

This approach is ideal for web servers, APIs, or any application that handles files dynamically in memory or over the network.

Conclusion

Converting PDF to HTML using Python is an effective way to make your documents web-compatible and more interactive. With Spire.PDF for Python, you get full control over the conversion process, from simple exports to advanced configurations like embedded images or SVGs and stream output.
