The Challenge of Comparing Scanned PDFs
Have you ever tried comparing two scanned PDFs only to find that the text is unrecognizable? You're not alone. A surprising number of professionals are often frustrated when faced with the task of comparing scanned documents, especially when the text isn't searchable. According to a study, almost 70% of businesses struggle with efficiently managing scanned documents, leading to lost productivity and errors. This is where Optical Character Recognition (OCR) comes into play.
Understanding OCR and Its Importance
What is OCR?
Optical Character Recognition (OCR) is a technology that converts different types of documents, such as scanned paper documents, PDFs, or images captured by a digital camera, into editable and searchable data. This transformation is vital for anyone who often works with scanned documents, especially when comparison is necessary.
Why Scanned PDFs Require OCR
1. Searchability: Scanned PDFs are essentially images of text, making them non-searchable. OCR allows you to convert these images into text that can be searched and compared.
2. Accuracy: When comparing documents, accuracy is paramount. OCR ensures that the text is recognized correctly, reducing the risk of errors during comparison.
3. Efficiency: Manual comparison of scanned documents is time-consuming. With OCR, you can automate the process, saving valuable time and resources.
