PDF OCR Text Extraction

Iron Tesseract can read many image formats, and also PDF documents. This feature is not possible with conventional free Tesseract engines.

OcrInput offers the option for PDF characteristics to be automatically corrected if scans are bad quality.

Developers may specify to read and entire PDF, a selection of pages or a single crop area.

C# PDF OCR

Many OCR tools work fine in optimum conditions, but when you need something that does the job with improved stability and accuracy in any conditions, the IronOCR text extraction solution is what you need.

IronOCR for text extraction is built from the ground up and with the ability to convert real-world images with 99 percent accuracy.

IronTesseract, our native C# OCR library, can recognize characters in almost human fashion from real-world images that are not always good quality and are sometimes skewed.

Our OCR allows PDF or image characteristics to be automatically corrected if scans are of poor quality. 

As I take you through the best-in-class OCR solution available right now, you will be able to see for yourself.

Do you have low-quality scans? No problem!

IronOCR stands out at a higher level when it comes to OCR tasks. In reality, many similar products are made to work well with machine-printed, high-resolution, and perfect text or images, and so they become inaccurate or fail in real-world applications. However, this is not the case with IronOCR.

IronOCR shines at correcting imperfect documents. It can straighten a skewed scanned image and enhance low-quality photos so that they become searchable PDF documents or images. This is what makes our product stand out from others.

Tune Iron OCR performance to fit your workflow

With the Iron Software OCR solution, you can tune the performance of your text extraction tasks in order to get the right balance for your workflow. We know this is very important to many users and developers, so we have built our OCR solution to be performance-adjustable and flexible. 

For example, one very important factor that influences the speed of an OCR job is the quality of the input image. When less background noise is present and concurrently has a higher dpi ( 200 dpi is a good range), the faster the yield and the more accurate the OCR results. However, with the IronOCR performance tuning feature, even tasks with low-quality images can be completed swiftly. 

Furthermore, choosing input images or scanned text formats with less digital noise, such as PNG or TIFF, can also yield quicker results than lower quality image formats such as JPEG.

Installing the IronOCR solution is a breeze

The Iron Software suite is very easy to install and run. It is available for the most popular development platforms. Our solution has cross-platform support that includes Windows, Linux, macOS, Azure, AWS, and Docker — there is a reason C# makes it the most preferred Tesseract OCR engine amongst developers.

Support for over 125 international languages

For OCR jobs, a particular software becomes more useful when it supports multiple languages. The IronOCR solution makes itself indispensable because it supports 125 international languages. These languages can be installed via language packs distributed as DLLs files. They can be downloaded from this website or the NuGet Package Manager for Visual Studio.

How To Install OCR Language Packs
