Part 2. What is a PDF Parser?

A PDF parser is a software that extracts information from a PDF, such as text, images, structure, font, and more. PDF parsers are important tools for many businesses and organizations because they can help with data extraction, document conversion, retrieving information, analyzing text, data mining, and so much more.

Many businesses use PDF parsers to automate their document processes and make their workflow easier.

Then they can view the parsed data for highlights, trends, and action items based on customer feedback.

Part 3. Why is PDF so Hard to Parse?

PDFs can be hard to parse because they are complicated. Some have lots of images, while others have a variety of different fonts and headings. Sometimes the structure of a PDF can make it difficult to parse.

Here are just a couple reasons why PDFs can be difficult to parse:

  • PDF files sometimes have complex structures with a lot of different elements, including text, images, tables, forms, and metadata.
  • Some PDF files are scanned documents that contain images instead of editable text, such as scanned receipts or purchase orders. For these kinds of images, you need OCR to extract the data, which is not always accurate.
  • PDFs have different levels of security. Some can be read by anyone, while other PDFs have passwords or are encrypted. These are difficult to parse because they need to be decrypted but still maintain data confidentiality in order to extract the data.
