Reads everything
The accuracy of text recognition heavily relies on the quality of the original image. Aspose OCR offers a comprehensive set of image processing filters, both fully automated and manual, to improve image quality before OCR processing.
Our powerful image processing and customizable content structure detection algorithms allow you to extract text from almost any image, from high-quality scans to blurry street photos. For optimal recognition results, you can apply multiple processing filters to the same image.
Scales to any task
Fine-tune the recognition process to your needs. Choose between high-accuracy thorough recognition or prioritize speed with fast recognition. Leverage the library’s automatic scaling based on your processor cores, or manually specify the number of threads for optimal performance. Free up valuable CPU resources by offloading calculations to the GPU.
Keep your application lean and modular by selectively adding advanced features from our online repository . For example, if you only need Arabic characters recognition, you may omit Chinese, Japanese, Korean, Hindi, Cyrillic and other OCR models, saving significant amounts of disk space.
Solutions
Aspose OCR library is suitable for any task, from personal to enterprise and government level. We’ll handle the technical implementation with maximum efficiency, regardless of the scale.

Advanced OCR engine
Most OCR libraries are based on open-source solutions that only perform well with basic scanned documents. However, such solutions often struggle with upside-down and inverted images, multi-column layouts and tables, street photos, and complex layouts. If your project demands exceptional accuracy for critical data extraction, you should consider the alternatives.
Developed and refined by our machine learning experts over years, Aspose OCR is built on a proprietary engine trained on extensive datasets. Continuously improved through customer feedback, it not only matches the capabilities of Tesseract but also outperforms in complex scenarios. When Tesseract struggles, Aspose OCR delivers exceptional accuracy, ensuring reliable text recognition in even the most challenging cases.
By offering a wide range of support options, we ensure lower maintenance costs for you, especially in the long term.
Control every aspect of recognition
Our OCR library delivers excellent recognition accuracy and performance out of the box. However, in some cases the default settings may not provide the most reliable recognition results, offering potential for further optimization.
The true power of our API lies in its flexibility and granular control over every recognition step. Fine-tune settings and create custom image preprocessing workflows to achieve the perfect balance between speed and accuracy for your specific needs.
