Compare PDF Files using Python REST API

This tutorial shows how to PDF Python developers can compare two PDF documents directly through the Aspose PDF Cloud REST API, using the official Aspose PDF Cloud SDK for Python. You’ll learn how to upload the source PDFs to cloud storage, run a comparison operation, and download the resulting file that highlights the differences. For more details on the PDF format, see the PDF file info page.

Prerequisite

  • Create an Aspose Cloud account and obtain your API credentials to compare two PDF documents.
  • Download the Aspose.PDF Cloud SDK for Python
  • Set up a Python project and add the SDK as a dependency.

Steps to Compare PDF Documents using Python Low Code API

  1. Import the Aspose.PDF Cloud SDK and the standard Python libraries required for file handling.
  2. Initialise the PdfApi with your Aspose Cloud credentials so the application can communicate with the service.
  3. Choose which PDF will serve as the original, which one will be compared, and decide on a name for the comparison result file.
  4. Open the first PDF file locally and upload it to Aspose Cloud storage.
  5. Open the second PDF file and upload it to the cloud as well.
  6. Execute the PDF comparison operation to generate a new document that visualises the differences.
  7. Inspect the API response to confirm that the comparison completed successfully.
  8. If the operation succeeded, download the resulting PDF and save it to your local machine.
  9. Display a clear error message if the comparison fails, making troubleshooting straightforward.

These steps summarise the workflow for comparing two PDF files using the Python REST API: connect to Aspose PDF Cloud, upload the PDFs, run the comparison, verify the response, and retrieve the diff‑highlighted result.

Code for PDF Comparison Tools using Python‑based API

Compare two PDFs using Python Low Code API is demonstrated in the sample above. Ensure the input files already exist in cloud storage before running the code. The output file name is specified in the PostComparePdf() method and should be used when downloading the result.
