Aspose.OCR for .NET
Overview
How to convert JPEG to PDF using C#
Aspose.OCR for .NET is a powerful yet easy-to-use and cost-effective library for converting JPEG images to PDF documents. Supporting 26 languages based on Latin, Cyrillic and Chinese, its state-of-the-art optical character recognition engine provides superior recognition speed and accuracy, while isolating you from formulas, neural networks, and other complex technical details. It allows you to add OCR functionality to your .NET applications in less than 10 lines of code.
processes scanned images or even smartphone photos in JPEG format and creates JPEG documents containing recognized text. To add it to your project, you just need to install the Aspose.OCR
package in your project with the following command:
Package Manager Console Command
PM> Install-Package Aspose.OCR
Steps to Convert JPEG to PDF
With .NET OCR and just a few lines of code, you can create full-featured application that converts an JPEG image to PDF document:
- Create an instance of AsposeOcr class
- Call AsposeOCR.RecognizeImage method
- Pass the JPEG file path as parameter
- AsposeOCR.RecognizeImage returns a String or file of PDF type
System Requirements
Before running the example, make sure that .NET API compatible with NET Standard 2.0 specification is installed on your system and all external dependencies of Aspose.OCR package are referenced in your project.
- NET Standard 2.0+ compatible solution
- Aspose.OCR for .NET referenced in your project.
This sample code shows JPEG to PDF .NET Conversion
// initialize an instance of AsposeOcr
AsposeOcr ocr = new AsposeOcr();
// recognize image
string riText = ocr.RecognizeImage("template.JPEG");
// print text
File. File.WriteAllText("document.PDF", riText);
JPEG What is JPEG File Format
A JPEG is a type of image format that is saved using the method of lossy compression. The output image, as result of compression, is a trade-off between storage size and image quality. Users can adjust the compression level to achieve the desired quality level while at the same time reduce the storage size. Image quality is negligibly affected if 10:1 compression is applied to the image. The higher the compression value, the higher the degradation in image quality.

Portable Document Format (PDF) is a type of document created by Adobe back in 1990s. The purpose of this file format was to introduce a standard for representation of documents and other reference material in a format that is independent of application software, hardware as well as Operating System. The PDF file format has full capability to contain information like text, images, hyperlinks, form-fields, rich media, digital signatures, attachments, metadata, Geospatial features and 3D objects in it that can become as part of source document.
