# Optical Character Recognition (OCR) .NET API

It is a standalone OCR API that enhances your .NET apps to [perform OCR on JPEG, PNG, GIF, BMP & TIFF images](https://docs.aspose.com/ocr/net/supported-file-formats/) for extraction of English, French, Spanish & Portuguese content.

[Aspose.OCR for .NET](https://products.aspose.com/ocr/net) not only provides the Optical Character Recognition engine but more. You can also apply Blur, Gaussian Blur, and Median filter to reduce noise before document recognition and can set the OcrEngine to ignore non-textual blocks, maintain correct text order during document text recognition & automatically correct spellings of the document text.
