How to Read Scanned Documents Using IronOCR

Many PDFs contain non-searchable, image-based text. IronOCR can convert this into searchable content, making it easier to locate specific information and enhancing document accessibility, especially for individuals with visual impairments.

Instead of manually copying or recreating text and images, automated extraction ensures accuracy and efficiency. This is particularly useful for research, legal documents, and content creation, where reusing specific portions of PDFs is common.

Businesses can extract critical data from PDFs for analysis or system integration, streamlining workflows. Designers and marketers can also extract images for enhancement and reuse in various projects.

In this tutorial, we'll explore the OcrPdfInput methods, covering the available options and parameters to showcase how IronOCR simplifies PDF text and image extraction for various applications.

To use this function, you must also install the IronOcr.Extensions.AdvancedScan package.

Quickstart: Extract Text from a Scanned PDF or Image

Get started in seconds—with one line of code you’ll load your scanned PDF or image using IronOCR’s OcrInput.LoadPdf or LoadImage and instantly extract the text via ReadDocument. Perfect for developers who want OCR up and running fast.
