In this article, we'll compare the top 5 best PDF parsers on the market in 2023 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.

1. Parseur to parse PDFs from any industry with many different layouts

Parseur is a powerful PDF parser that provides a fast and easy way to extract information from PDF documents and turn it into structured data. The OCR technology used in Parseur is advanced and can accurately recognize text even in complex and multilingual documents.

Invoice data extraction with Parseur

What makes Parseur unique is that it has developed its own standalone OCR extraction feature called Dynamic OCR.

Zonal OCR has its own challenges; for example, it cannot extract data that moves dynamically across a document. As a solution, Parseur has developed Dynamic OCR which easily extracts variable fields.

3. Docparser for parsing documents with the same layout

Docparser: Zonal OCR

Docparser: Great for parsing documents with the same layout

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.

Nanonets: Best for high volume invoices extraction in English

Nanonets is an AI platform that makes it easier for businesses to build and deploy custom image and document recognition models.

The platform provides a user-friendly interface that makes it easy to create and customize models, even for those without prior machine learning experience.

You can build your own extractor by training the AI model.


  • Limited features are available on the free plan. For example, you cannot extract table data.
  • Data quality for parsing documents in languages other than English can vary.
  • Training the custom model is time-consuming since a minimum of 10 annotated documents are required for the training. On top of that, on the free plan, you cannot create more than 5 labels (i.e. fields).
  • Nanonets’ pricing plans are quite expensive as they start at $499, which is $0.1/page.
