OCR Ranking 2025 – Comparison of the Best Text Recognition and Document Structure Software
OCR (Optical Character Recognition) technologies have come a long way – from simple character reading in document scans to advanced systems recognizing the structure of invoices, forms or tables. In the era of business process automation, however, it is not only the recognition of text that is crucial, but also understanding the context and layout of the document. In our practical test, we compared 8 leading OCR tools in terms of their effectiveness in processing real business documents. Here are the results.
The New Face of OCR – Intelligent Processing of Business Documents
Text recognition based on document and image scans is no longer just an addition to archiving systems – in many organizations it is the foundation of process automation, such as accounting, logistics, HR or compliance with regulations. Modern OCR tools are no longer just text extraction engines, but complex AI systems that can recognize the structure of documents, identify data fields, segment tables or understand the context of information contained in forms.
In corporate environments, OCR is increasingly expected not only to “read” documents, but also to understand them – e.g. distinguishing the invoice header from the goods item line, extracting the payment date, NIP number, gross amount or recipient data. What’s more, these documents come in various formats – from editable PDFs, through scanned images, to photos sent from mobile devices. In addition, they are often bilingual – e.g. Polish-English invoices for foreign partners.
That is why more and more attention is being paid to testing OCR tools in the context of real applications – not only in terms of precision of letter recognition, but also in terms of the quality of document layout mapping, structural consistency, data completeness and processing flexibility.
In our test, we focused on exactly this – comparing the effectiveness of different OCR engines in recognizing the structure of real structured documents. We tested 8 popular tools – both commercial cloud solutions and open-source frameworks that can be implemented locally or modified to suit your needs. All of them passed the same set of tests based on the analysis of a 10-page document package containing invoices, forms, declarations, customs documents and numeric-text tables – in Polish and English, in various input formats.
Later in the article, we will show which tools coped best with data mapping, what difficulties they had, and which of them offer the best possibilities within several categories. If you are faced with choosing OCR technology for your project, this ranking will provide you with hard data, not marketing declarations.
How We Tested Text Recognition Software? OCR Tool Comparison Methodology
Choosing the best OCR tool cannot be based solely on manufacturer declarations or function descriptions. In order to reliably compare the capabilities of available solutions, it was necessary to design a test that reflects real business scenarios in which text recognition technologies and document structures are most often used.
Purpose of OCR Test
Our focus was not only on the precision of text recognition, but above all on the ability of tools to interpret the layout of a structured document – to recognize data fields, tabular structures, header sections and logical relationships between document elements.
In practice, this meant analyzing the results against the following metrics:
- data completeness (whether all relevant information was recognized)
- field extraction correctness (whether, for example, “Issue Date” was correctly extracted as a separate value)
- hierarchy and segment mapping (e.g., separation of headers from product lines)
- table and column segmentation correctness
- identification of numeric versus text data
- correctness when recognizing bilingual documents
OCR Test Set
All tools passed the same test – they processed the same set of documents prepared from real examples encountered in everyday business work. The tests included both PDF files (editable and scanned) and images, and the results were sent in JSON, XLSX or TXT format – depending on the output format of the tool. The test package contained 10 pages in Polish and English, representing the following types of documents:
- VAT and proforma invoices
- forms and declarations
- customs and logistics documents
- transfer confirmations
- tables of goods items and numerical data
Results and Analysis of Results
The text recognition results were saved by us in native formats for a given tool: JSON, XLSX or TXT. The format was not assessed, as long as it contained data that could be structurally compared. The key element of the assessment was the ability to map:
- field labels and values
- tabular items
- logical relations (e.g. which value applies to which header)
- compliance with reference data
For the comparison, we used semi-automatic analytical tools and manual validation, especially where it was required to analyze the meaning of data and the relations between data (e.g. whether “Issue Date” was not recognized as “Sale Date”). Each tool was evaluated using uniform test data, and the scoring was standardized to easily compare different approaches: commercial APIs, open-source, AI/ML models, classic OCR, layout parsers, etc.
The scoring description for the comparison columns is as follows:
