What Is Optical Character Recognition (OCR)? Cost, Capabilities, and Limitations
Has your organization ever struggled to locate a specific record — or even a single piece of information within a document? One of the most effective ways to solve this problem is through document imaging combined with Optical Character Recognition (OCR).
By converting paper records into searchable digital files, OCR makes it possible to instantly locate information across thousands of documents. When paired with secure records management, it becomes a powerful tool for improving efficiency and compliance.
What Is OCR and How Does It Work?
OCR (Optical Character Recognition) is a technology that converts scanned images of text into searchable, machine-readable data.
After documents are digitized through document imaging, OCR software analyzes each page, identifying characters such as letters and numbers. It compares these against a built-in character library and converts the content into searchable text.
The result is a digital file that allows users to search for keywords across an entire database — dramatically improving document retrieval speed and accuracy.
OCR can be applied during the scanning process or added later to existing digital files.
Key Benefits of OCR
- Search documents instantly by keyword
- Reduce time spent locating records
- Improve workflow efficiency
- Enhance compliance and audit readiness
- Minimize reliance on physical storage
Combined with records storage and indexing, OCR transforms how organizations manage and access information.
OCR Capabilities
Modern OCR software can recognize text across a variety of formats, including:
- Printed documents
- Tables and structured data
- Images containing embedded text
- Forms and reports
This allows organizations to unlock data that would otherwise remain trapped in static image files.
OCR Limitations
While OCR technology has advanced significantly, it still has limitations — especially when working with handwritten or low-quality documents.
Accuracy may be affected by:
- Illegible handwriting
- Cursive or inconsistent writing styles
- Faded or damaged documents
- Low-resolution scans
Printed text typically produces the most accurate results, while handwritten content may require manual verification.
OCR File Formats
During document imaging, files are often created as image formats such as TIFF or JPEG. When OCR is applied, a searchable text layer is added, commonly within a PDF file.
This allows users to search text while preserving the original document image for reference and compliance purposes.
OCR Storage and Processing Considerations
OCR increases the size of digital files because it adds a searchable text layer. As a result:
- Larger databases require more storage space
- Processing time increases with database size
- System performance may be impacted for very large datasets
Organizations should plan for additional storage and processing needs when implementing OCR.
OCR Costs
OCR costs are typically tied to storage usage rather than the OCR process itself.
Because OCR increases file size, it can raise overall storage requirements and associated costs.
For example:
- A 10 GB database may increase to 13 GB after OCR is applied
- Some providers enforce minimum storage thresholds
- Larger databases require more processing time and resources
Despite these costs, OCR often delivers significant long-term value by improving efficiency and reducing time spent searching for information.
