6 Best Online OCR Tools

6 best online OCR tools




Global digitalization has changed the way we live and work. It has replaced faxes with emails, letters with emails, handwriting with typing, written documents with printed documents. Most lately, it created the so-called paperless trend where offices and schools replace paper with tech devices and tools. While more and more businesses across the globe turn to this trend, some types of documents, such as receipts, invoices, and forms, are still printed. To be able to process these files while keeping up with digitalization, businesses have turned to OCR tools or OCR converters.

What Are OCR Tools and How Do They Work?

Optical Character Recognition (OCR) tools are web-based tools that turn images of printed documents and electronic formats like PDFs into readable, searchable, and editable files. They are easy to use and don’t require any special knowledge to use them. By using an OCR tool, you save a lot of time, money, and effort since you don’t have to manually rewrite all the information found on those files. These tools use OCR technology, which converts text from various types of physical and digital files into machine-readable data. Therefore, OCR tools can recognize text from images, photos, and printed or scanned documents and extract the same. The extracted text can then be used for various purposes, such as data entry. Database creation, or information indexing. Also, they can convert the extracted text into various file formats like CSV, XML, XLSX, etc.

The Evolution of OCR Tools

Back in the 70s, when the OCR tools have first appeared, they weren’t nearly as sophisticated as those we have today. Many things have changed throughout the years, with Artificial Intelligence and Machine Learning taking over the OCR technology. Apart from these two technologies, the Natural Language Processing (NLP) technique has also been incorporated. This has allowed OCR tools to understand the context of the text being extracted. In addition, OCR tools nowadays can be used on documents of any format and non-standard ones. Thanks to all these advances and technologies incorporated in these tools, they can serve for much more than extracting text from printed and digital files. They can understand their meaning, detect frauds, and so on.

Benefits of Using OCR Tools

Using OCR tools for extracting text from printed and digital files has numerous benefits for businesses, including:
  • Allows for easy access - Users can easily search for specific files using their personal information. Since the system uses OCR technology, all files can be searched by data like names, numbers, and addresses.
  • Reduces time - OCR tools save a lot of time since they do all the hard work of manually rewriting or transcribing files.
  • Improves files conversion and data usability - Using an OCR tool, you can easily edit and manage files as well as convert them from one file format to another.
  • Reduces costs - OCR tools have low-cost processing, which saves your budget.
  • Improves productivity - Since working with OCR reduces time, effort, and stress, it creates a more relaxed working environment, which results in greater productivity.
  • Boosts speed - By extracting text from printed and digital documents and converting it into readable and editable data, OCR speeds up the process of data management.
  • Increases accuracy and data usability - By having text extraction done by AI-powered and Machine-Learning-based OCR tools, the text is very accurate and ensures better data usability. The higher accuracy makes the content more valuable to clients and allows businesses to control data quality.
  • Improves customer service and increases customer retention - By using OCR tools, you can serve your customers faster and more effectively. It’s because it converts all your data into a digital format that is easy to access. This not only improves customer service but also increases your customer retention.

How to Choose the Right OCR Tool for Your Business?

There are many OCR tools available on the market, but all of them are the same. They differ in their technology, features, and price. Also, not all of them match your business needs and requirements. So, how to choose the right OCR tool for your business? To do that, you need to look at the OCR tool that:
  • Works with standard and non-standard formats.
  • Supports all languages or, at least, all commonly spoken languages.
  • Is SaaS-based, not software that needs to be installed because those tools improve over time and offer users more features.
  • Can detect handwritten text - not a must, but definitely a big plus.
  • Isn’t template-based because they perform poorly.
  • Matches your business needs - look at its features to see if it can do whatever you need.
  • Matches your budget, but make sure you look at the total cost of the tool, not only the price of the product (one-time payment or monthly fee or completely free).
