Optical Character Recognition (OCR) is no longer just about converting scanned pages into readable text. In today’s data-driven world, the OCR output format you choose can directly impact searchability, compliance, long-term preservation, automation, and integration with modern applications. From simple text extraction to structured, machine-readable data, each format serves a distinct purpose.
In this detailed guide, we’ll compare the most commonly used OCR output formats—TXT, PDF, PDF/A, XML, and JSON—to help you choose the right one for your workflow, whether you’re building an open-source OCR pipeline, an enterprise document system, or an AI-powered analytics platform.
Understanding OCR File Formats - HOCR vs ALTO vs PDF/A Explained
Last Updated: 05 Jan, 2026
If you’ve ever scanned a document and wondered how computers transform images of text into searchable, editable content, you’ve encountered the world of Optical Character Recognition (OCR). But the story doesn’t end with simply extracting text from images. The real magic happens in how that information gets stored and structured.
When you digitize historical archives, process business invoices, or convert printed books into digital libraries, choosing the right OCR output format becomes critical.
PDF/A-3 - The Hybrid Monster? Embedding Original Data Inside Your OCR
Last Updated: 29 Dec, 2025
In the world of document digitization, OCR (Optical Character Recognition) is often seen as the final step—scan, recognize text, archive, done. But modern compliance, automation, and data-driven workflows demand more than just searchable PDFs. They require traceability, machine-readable structure, and long-term archival guarantees.
This is where PDF/A-3 enters the scene—often misunderstood, sometimes controversial, and undeniably powerful. Many developers call it “the hybrid monster” because it allows something earlier PDF/A standards strictly forbade: embedding original source files directly inside an archival PDF.

Why SVG is The Most Underrated Image Format
Last Updated: 15 Dec, 2025
When most people think of image formats, they picture JPEGs for photos, PNGs for transparent graphics, and GIFs for animations. But there’s another format quietly powering much of the modern web that deserves far more recognition: SVG (Scalable Vector Graphics). Despite being available for over two decades, SVG remains one of the most underutilized and misunderstood image formats—even though it solves many problems that plague other image types.
