Best PDF Parser Software in 2024

In this article, we'll compare the top 5 best PDF parsers on the market in 2024 based on their accuracy, speed, pricing and overall functionality.

PDFs (Portable Document Format) have become the standard for document sharing and exchange in literally every organization now. In today's digital age, the ability to extract and process data from PDF files is a crucial requirement for many businesses. However, with the increasing demand for PDF parsing tools, the market has become flooded with various options, making it difficult to choose the best one.

What is a PDF parser?

A PDF parser, also known as a PDF scraper is an automation tool that extracts data from PDFs such as scanned documents, invoices, purchase orders, and bills of lading, among others.

PDF parsing tools are often integrated with other technologies such as optical character recognition (OCR), artificial intelligence (AI), natural language processing (NLP), and machine learning (ML).

The parsed data can be downloaded in different formats or further analyzed for advanced data processing.

Integrating a PDF parser in your business processes

Using PDF parsing software can bring numerous benefits to your business, including increased efficiency, accuracy, scalability, cost savings, and improved security.

  • Minimal or zero manual interventions: manual processes such as extracting specific data from an invoice can be automated

  • Improve data accuracy: manual copy-pasting increases the risk of errors which can lead to a loss in revenue. PDF parser reduces that risk and enhances data quality.

According to a report from Dun & Bradstreet, almost 20% of businesses have lost a customer due to using incomplete or inaccurate information about them.

  • Seamless integration with other applications: The PDF scraper is easily integrated with your CRM, ERP or any other tools and data sent in real-time.

  • Scalability: PDF parsers can handle large volumes of data which makes it easier to scale as your business grows.

The document parsing software offers different templates such as invoices, bank statements or bills of lading which are parsed automatically. Docparser uses Zonal OCR and customizable rules to extract data from documents; but, you'll need to create custom parsing rules to match your specific needs.


  • It takes time to understand how the parsing rules work especially if you are not tech-savvy.
  • Docparser is not flexible enough in terms of customization. For example, documents with different formats and layouts will need to be split into their own inbox, which can be a bit tedious to set up if you have many different layouts.
