Add optical character recognition (OCR) to your .NET applications, web sites and cloud services with a few lines of code. Effortlessly transform images into machine-readable text and generate searchable PDFs from scanned pages.
Aspose.OCR for .NET is a robust, developer-friendly, and cost-effective API for optical character recognition. In less than 10 lines of native C# code, you can build OCR capabilities into your .NET desktop solutions, MVC-based Web applications, cloud services, and serverless Azure functions. Extract machine-readable text from scans, photos and screenshots, convert scanned pages into searchable and indexable PDFs, find and compare text on images focusing at business task rather than complex maths, neural networks, and other technical intricacies.
Multi-page PDF documents, TIFF and DjVu images are fully supported.
