Apryse Announces Acquisition of AI-Powered Document Toolkit Provider LEAD Technologies

Build Better Apps with LEADTOOLS

Powered by patented artificial intelligence and machine learning algorithms, LEADTOOLS is a collection of comprehensive toolkits to integrate recognition, document, medical, imaging, and multimedia technologies into desktop, server, tablet, web and mobile solutions.


Extract machine-printed and handwritten text with unparalleled speed and accuracy to develop robust, scalable, high-performance recognition and document processing applications. Whether you want to convert images to searchable or editable documents such as PDF and DOCX, or extract values from fields on a form, business cards, invoices, and identification documents such as passports the LEADTOOLS OCR APIs give you the power to make it happen.


Detect, read, and generate over 100 barcode types using libraries that maximize high-speed processors and automatically take advantage of multiple threads and cores by utilizing the fastest barcode recognition speed within the LEADTOOLS Barcode SDK.


Implement reliable and multi-threaded PDF functionality with a comprehensive PDF API to read, write, convert, and view PDF files without the need for third-party dependencies like Acrobat.

Forms Processing

Forms come in a variety of shapes, sizes, and uses, and LEAD's patented forms classification libraries and AI-enhanced tools will handle them all. In addition to basic forms recognition with static field locations, LEADTOOLS libraries can detect and process unstructured and loosely structured documents such as invoices, business cards, and passports.

Document Editor

Create robust, full-featured applications with rich document-editing capabilities, including text search, annotation, speech recognition, memory-efficient paging, inertial scrolling, and vector display. The LEADTOOLS Document Editor is a zero-footprint document-editing solution.

Document Viewer

Developers can create robust, full-featured applications with rich document-viewing features, including text search, annotation, memory-efficient paging, inertial scrolling, and vector display. With only a few lines of code, the LEADTOOLS Document Viewer can be added to any project.

Document Converter

Create powerful, automated document conversion, archival, and delivery systems using LEADTOOLS. Under the hood, the Document Converter uses artificial intelligence to intelligently select a combination of the LEADTOOLS Raster, SVG, OCR, and Document Writer technologies to convert images and documents using the best possible blend of accuracy and speed.

Document Analyzer

The Document Analyzer intelligently detects and extracts text, paragraphs, or any key-value from text-based office documents (DOC, DOCX, XLS, XLX), PDFs, and document images (JPG, TIFF, PNG PDF) based on rules. This smart data extraction automatically finds key phrases within structured and unstructured documents such as invoices, statements, bills, and receipts, even if the layouts between files are completely different.


Create entire DICOM-compatible applications that include DICOM data sets, directory (DICOMDIR), secure communication, security, 2D and 3D viewers, video playback, and medical-specific image viewing and processing. Following the latest DICOM specification, the LEADTOOLS DICOM APIs support all IODs with or without optional modules and elements.


LEADTOOLS provides easy to use, low and high-level components to rapidly develop an entire PACS solution or any component of a PACS workflow. Implement DICOM Communications to query, retrieve, and store DICOM data sets and pixel data between PACS clients and servers.

Medical Viewer

LEADTOOLS includes several Medical Viewers to display DICOM data sets and pixel data. Each viewer includes advanced medical-specific features such as multi-cell and sub-cell layouts, 16-bit extended grayscale, window leveling, image stack, metadata tags, annotations and markup, reference lines, and cine.


LEADTOOLS Multimedia SDK products are specifically designed for the development of audio/video applications across a wide variety of industries, including defense, broadcast, and security. The SDKs offers a full range of libraries to developers and turns normally complex DirectShow and Media Foundation projects into simple tasks.

Image Viewer

Comprehensive image and document rendering controls for desktop, web, tablet and mobile devices. LEADTOOLS viewers include many core features including high-level user-interactive modes, annotation and mark-up, thumbnail display, touchscreen input and support for hundreds of image and document formats.

Image Processing

LEADTOOLS Image Processing libraries are the fastest, most robust, and most accurate functions available with over 200 image processing functions, including document cleanup, medical image enhancement, color conversion and correction, noise reduction, and edge detection.

Virtual Printer

LEADTOOLS Virtual Printer Driver can capture output from any application that can print, including Word, Excel, and web browsers. It is a gateway for your legacy applications to access the power of the LEADTOOLS libraries and modern workflows.

Office Formats

With LEADTOOLS, developers can create applications to load, save, and convert many industry-standard and proprietary formats. LEAD Technologies is committed to maintaining and expanding the most comprehensive support of file formats on the market including all major document and Office formats: PDF, PDF/A, DOC/DOCX, XLS/XLSX, PPT/PPTX and more.
