Are you finding solutions on how to preserve or retain links from PDF files or export hyperlinks from PDF file to text file for future use?
A Portable Document Format or PDF is a premier file format for sharing information / report or any official / legal documents. Sometimes, these PDF files contain some hyperlink text or URLs. Now, you want to extract all the URLs from PDF files to preserve them or retain them for future reference.
In this blog, I am going to describe the working of an remarkable tool designed by SysTools to extract hyperlinks from PDF and save them in a PDF/ DOC/ DOCX file. Also, we will see how we can use Python language to extract URLs from PDF.
Extract Hyperlinks From PDF Files Using Python PyPDF2 Lib.
Step-1: Install PyPDF2 on your local system by typing pip install PyPDF2 in the command shell.
Step-2: Import PyPDF2.
Step-3: Open the PDF in Binary mode and it recognizes links in the file.
Step-4: Define a function to extract the hyperlink for a particular PDF page.
Step-5: Iterate for all the pages and extract the text using extractText() function.
Step-6: To extract the hyperlinks from PDF, a Pattern Matching Concept in Python is used. Now you have to import re to find the pattern using regular expressions.
Step-7: Finding the pattern that matches with http:// or https:// using findall(regex, string).
Step-8: If any URL/ link found, return the URL by printing it on the screen.
Here is the Python Code to Extract Links From PDF File
# Importing packages
# Open your File in the Command
file = open(“newfile.pdf”, ‘rb’)
readPDF = PyPDF2.PdfFileReader(file)
#Find all the String that matches with the pattern
regex = r”(https?://\S+)”
url = re.findall(regex,string)
for url in url:
# Iterating for all the pages of File
for page_no in range(readPDF.numPages):
#Extract the text from the page
text = page.extractText()
# Print all URL
# Close the file
Well, the above method can be too much programmatic for some users, so to ease your task you can follow the automatic solution.
