Compare two PDF files in Python using our difference checker. With our high-fidelity Python via .NET API, you can find the difference between compared PDF documents and export the results to a convenient file format.
With this native Python via .NET API, you can easily compare PDF documents and obtain the differences in the desired output format. Our Python library is fully self-contained and does not rely on any external tools or services. It eliminates the need for external dependencies, providing a comprehensive set of PDF processing functionalities within a single Python via .NET package.
On this landing page, we bring you a live demo of the PDF comparison in action, coupled with an illustrative Python example. It compares the contents of PDF documents both at the character level and at the word level. Even if only a single character has been changed, the entire word will be marked as modified. Experience firsthand how easy it is to compare two documents by uploading PDF files to the interface, choosing the desired output format, and getting the differences between PDF documents marked with 100% accuracy.
Sometimes it may not be clear if a PDF file has been modified, and manually comparing two versions of a document can be a daunting task. Conversely, there are times when you're sure the PDF document has changed, but visually identifying the updated sections becomes overwhelming. The PDF comparison is an increasingly sought-after procedure, particularly within automated document workflows. Let's explore typical scenarios where automated PDF comparison can be highly valuable:
As you can see, programmatic PDF comparison offers immense benefits in various domains, enabling streamlined workflows, enhanced collaboration, and increased productivity. With this Python API, you have the power to harness these advantages seamlessly within your Python via .NET projects. Try out our live demo by uploading two PDF documents, selecting the target format to highlight the differences, and examining the Python code example. This Python snippet demonstrates how to find differences between PDF files and save the results in the required format.
An important point: the compared PDF documents should not have revisions before calling the comparison method. You must first accept all the revisions.
import aspose.words as aw
docA = aw.Document("Input1.pdf")
docB = aw.Document("Input2.pdf")
# There should be no revisions before comparison.
docA.compare(docB, "Author Name", datetime.now())
This package is compatible with Python ≥3.5 and <3.12. If you develop software for Linux, please have a look at additional requirements for gcc and libpython in Product Documentation.
