Top 3 Best Online PDF OCR Services

What is OCR?

OCR (Optical Character Recognition) is known for converting texts in an image or documents into machine-encoded text. This is a common method used for turning machine unreadable data entries with the assistance of AI (Artificial Intelligence) into digital texts.

One of the advantages of using PDF is the ability to maintain the exact format even if it is opened through different software. As a result, there are PDF files where the text inside it cannot be edited because the source of the document is an image or does not allow editing. OCR services allow the user to extract the texts in the file for easier use such as copy-pasting the information. It saves the user’s time and effort to manually type the document into a more digitally recognized format.
