7 Ways To Convert Images to Text Using OCR

default image

Optical character recognition (OCR) technology has become an indispensable tool for converting text in images into editable and searchable text. With OCR, you can take a photo of a document or screenshot and extract the text so you can edit or share it digitally.

OCR software works by analyzing an image and identifying patterns in the text to determine the letters and words present. This text can then be exported into a variety of digital formats like .docx, .txt, and .pdf.

The demand for OCR continues to grow as more paper documents get digitized and digital images need to be made searchable. Thankfully, OCR tools are now available as apps for mobile devices, programs for computers, and handy online converters.

In this guide, we will explore 7 effective ways you can use OCR to extract text from images, on any device:

1. Use an Online OCR Converter

One of the easiest ways to convert an image to text is through an online OCR converter. These tools allow you to upload an image or take a screenshot directly and will process the image file on their servers using OCR.

Some of the top online OCR converters include:

  • NewOCR – Recognizes over 60 languages and offers advanced editing of extracted text.

  • OnlineOCR – Supports multiple languages and can handle low resolution images.

  • FreeOCR – Easy to use with no signup required and unlimited extractions.

The benefit of online OCR converters is you don’t need to download any software. They also tend to offer quick processing speeds since the image gets processed on remote servers.

To use an online OCR tool:

  1. Go to the website for the OCR converter.
  2. Upload your image file from your computer or take a screenshot.
  3. The OCR tool will process the image and extract the text.
  4. You can then copy or download the extracted text.

One limitation with online OCR converters is they may not perfectly replicate complex formatting like columns, tables, or font styles. But they work great for basic documents.

2. Use Google Drive OCR

If you already use Google Drive for file storage, you can convert images to text right within Google Docs.

Google provides built-in OCR technology that automatically extracts text when you upload an image. Here‘s how to use it:

  1. Upload your image file to Google Drive.
  2. Right click on the image and select Open With > Google Docs.
  3. The image will open in Google Docs with the extracted text laid over the image.
  4. You can now copy the text or save the document.

Google Drive OCR does an impressive job at recognizing fonts, sizes, colors, and paragraphs from complex documents. The extracted text closely replicates the original formatting.

This makes Google Drive a great option for OCR needs if you already have the app installed. The only limitation is it requires an internet connection to process images.

3. Use OCR Software on Windows

To use OCR software on Windows:

  1. Install and open the OCR desktop application.
