PDF files are everywhere—from contracts and research papers to eBooks and invoices. While they preserve formatting perfectly, extracting text from PDFs can be challenging, especially with large or complex documents. Manual copying is not only slow but often inaccurate.
Whether you’re a developer automating workflows, a data analyst processing content, or simply someone needing quick text extraction, programmatic methods can save you valuable time and effort.
In this comprehensive guide, you’ll learn how to extract text from PDF files in Python using Spire.PDF for Python — a powerful and easy-to-use PDF processing library. We’ll cover extracting all text, targeting specific pages or areas, ignoring hidden text, and capturing layout details such as text position and size.

Extract Text from PDF (Basic Example)
If you just want to quickly read all the text from a PDF, this simple example shows how to do it. It iterates over each page, extracts the full text using PdfTextExtractor, and saves it to a text file with spacing and line breaks preserved.
from spire.pdf.common import *
from spire.pdf import *
# Create a PdfDocument object
doc = PdfDocument()
# Load a PDF document
doc.LoadFromFile('C:/Users/Administrator/Desktop/Terms of service.pdf')
# Prepare a variable to hold the extracted text
all_text = ""
# Create a PdfTextExtractOptions object
extractOptions = PdfTextExtractOptions()
# Extract all text including whitespaces
extractOptions.IsExtractAllText = True
# Loop through all pages and extract text
for i in range(doc.Pages.Count):
page = doc.Pages[i]
textExtractor = PdfTextExtractor(page)
text = textExtractor.ExtractText(extractOptions)
# Append text from each page
all_text += text + "\n"
# Write all extracted text to a file
with open('output/TextOfAllPages.txt', 'w', encoding='utf-8') as file:
file.write(all_text)
Advanced Text Extraction Features
For greater control over what and how text is extracted, Spire.PDF for Python offers advanced options. You can selectively extract content from specific pages or regions, or even with layout details, such as text position and size, to better suit your specific data processing needs.
Retrieve Text from Selected Pages
Instead of processing an entire PDF, you can target specific pages for text extraction. This is especially useful for large documents where only certain sections are relevant for your task.
from spire.pdf.common import *
from spire.pdf import *
# Create a PdfDocument object
doc = PdfDocument()
# Load a PDF document
doc.LoadFromFile('C:/Users/Administrator/Desktop/Terms of service.pdf')
# Create a PdfTextExtractOptions object and enable full text extraction
extractOptions = PdfTextExtractOptions()
# Extract all text including whitespaces
extractOptions.IsExtractAllText = True
# Get a specific page (e.g., page 2)
page = doc.Pages[1]
# Create a PdfTextExtractor object
textExtractor = PdfTextExtractor(page)
# Extract text from the page
text = textExtractor.ExtractText(extractOptions)
# Write the extracted text to a file using UTF-8 encoding
with open('output/TextOfPage.txt', 'w', encoding='utf-8') as file:
file.write(text)
Get Text from Defined Area
When dealing with structured documents like forms or invoices, extracting text from a specific region can be more efficient. You can define a rectangular area and extract only the text within that boundary on the page.
from spire.pdf.common import *
from spire.pdf import *
# Create a PdfDocument object
doc = PdfDocument()
# Load a PDF document
doc.LoadFromFile('C:/Users/Administrator/Desktop/Terms of service.pdf')
# Get a specific page (e.g., page 2)
page = doc.Pages[1]
# Create a PdfTextExtractor object
textExtractor = PdfTextExtractor(page)
# Create a PdfTextExtractOptions object
extractOptions = PdfTextExtractOptions()
# Define the rectangular area to extract text from
# RectangleF(left, top, width, height)
extractOptions.ExtractArea = RectangleF(0.0, 100.0, 890.0, 80.0)
# Extract text from the specified area, keeping white spaces
text = textExtractor.ExtractText(extractOptions)
# Write the extracted text to a file using UTF-8 encoding
with open('output/TextOfRectangle.txt', 'w', encoding='utf-8') as file:
file.write(text)
Ignore Hidden Text During Extraction
Some PDFs contain hidden or invisible text, often used for accessibility or OCR layers. You can choose to ignore such content during extraction to focus only on what is actually visible to users.
from spire.pdf.common import *
from spire.pdf import *
# Create a PdfDocument object
doc = PdfDocument()
# Load a PDF document
doc.LoadFromFile('C:/Users/Administrator/Desktop/Terms of service.pdf')
# Create a PdfTextExtractOptions object
extractOptions = PdfTextExtractOptions()
# Ignore hidden text during extraction
extractOptions.IsShowHiddenText = False
# Get a specific page (e.g., page 2)
page = doc.Pages[1]
# Create a PdfTextExtractor object
textExtractor = PdfTextExtractor(page)
# Extract text from the page
text = textExtractor.ExtractText(extractOptions)
# Write the extracted text to a file using UTF-8 encoding
with open('output/ExcludeHiddenText.txt', 'w', encoding='utf-8') as file:
file.write(text)
Retrieve Text with Position (Coordinates) and Size Information
For layout-sensitive applications—such as converting PDF content into editable formats or reconstructing page structure—you can extract text along with its position and size. This provides precise control over how content is interpreted and used.
from spire.pdf.common import *
from spire.pdf import *
# Create a PdfDocument object
doc = PdfDocument()
# Load a PDF document
doc.LoadFromFile('C:/Users/Administrator/Desktop/Terms of service.pdf')
# Loop through all pages of the document
for i in range(doc.Pages.Count):
page = doc.Pages[i]
# Create a PdfTextFinder object for the current page
finder = PdfTextFinder(page)
# Find all text fragments on the page
fragments = finder.FindAllText()
print(f"Page {i + 1}:")
# Loop through all text fragments
for fragment in fragments:
# Extract text content from the current text fragment
text = fragment.Text
# Get bounding rectangles with position and size
rects = fragment.Bounds
print(f'Text: "{text}"')
# Iterate through all rectangles
for rect in rects:
# Print the position and size information of the current rectangle
print(f"Position: ({rect.X}, {rect.Y}), Size: ({rect.Width} x {rect.Height})")
print()
