You've just received a 50-page contract that needs to be reviewed, but there's a catch: it's a scanned PDF. You know it is going to be a daunting task ahead. There is no search function, no copy-paste, and no easy editing.

Retyping the entire document into a Word file or converting the scanned PDF into an editable one may take forever. What's the alternative? OCR, or Optical Character Recognition, is the answer. 

Let's explore what OCR software is and how it can help you convert scanned PDFs into editable Word documents quickly and easily. We'll provide step-by-step instructions and share expert tips to help you achieve the best possible results.

Understanding OCR: What it is and how it works

(This section includes the definition of OCR, a step-by-step process of how it works, a comparison between regular PDFs and scanned PDFs, the importance of OCR in today's digital age, and an introduction to AI-powered OCR. Feel free to skip this section if you're already familiar with these concepts)

OCR allows you to extract text from images and scanned documents. It helps convert scanned PDFs into editable Word files.

Here's a step-by-step process of how OCR works:

  1. Scanning: The physical document is scanned using a scanner, camera, or a smartphone camera to create a digital image.
  2. Pre-processing: The scanned image is enhanced to improve its quality. This may include techniques like deskewing (correcting the alignment), despeckle (removing noise), and binarization (converting the image to black and white).
  3. Text recognition: The image is then analyzed by the OCR software, which uses pattern recognition algorithms to identify individual characters, numbers, and symbols. It breaks down the image into smaller components, such as lines, words, and characters, and compares them against a pre-existing database of patterns to recognize the text.
  4. Post-processing: The OCR software then performs post-processing tasks to improve the accuracy of the output. This may include correcting errors, removing irregularities, and formatting the text into a structured document.
  5. Output: Finally, the OCR software generates a machine-readable text file, such as a Word document or a searchable PDF, which can be easily edited, searched, and integrated into various business processes.

Let's take a look at the difference between regular PDFs and scanned PDFs:

Regular PDFs Scanned PDFs
Created from digital sources Created from physical documents
Contains machine-readable text Essentially just images of the pages
Can be easily edited and searched Requires OCR to convert into editable text

The importance of OCR in today's digital age cannot be overstated. By automating the process of converting scanned documents into editable formats, OCR helps businesses:

  • Automate converting scanned documents and images into editable and searchable text.
  • Eliminate the need for manual data entry and minimize the risk of errors and the associated costs of correcting them.
  • Extract data from documents with a high degree of precision, reducing the risk of errors that can lead to costly mistakes or compliance issues.
  • Quickly digitize and centralize their document management, making accessing and analyzing data easier.
  • Scale document processing capabilities without the need for additional manual labor.
  • Recognize text in multiple languages and even translate the content into a different language.

What is AI-powered OCR?

While traditional OCR relies on pre-defined rules and patterns to recognize text, AI-powered OCR takes it to the next level. By leveraging machine learning algorithms, these advanced systems can adapt to various fonts, styles, and layouts without breaking a sweat.

AI-powered OCR outperforms traditional systems in processing complex documents, including those with tables, graphs, and handwritten text. It delivers highly accurate results, saving hours of manual work. And the best part? By automatically extracting valuable insights from scanned documents, businesses can make informed and data-driven decisions.

Nanonets is a leading AI-powered OCR solution that can handle a wide range of documents, from simple contracts to complex invoices and receipts. Its intelligent algorithms can accurately extract text, tables, and key-value pairs from scanned PDFs, making it an ideal choice for businesses looking to automate their document processing workflows.

Tips and tricks to achieve optimal scanned PDF to Word results

Nobody wants to spend hours and hours manually editing and formatting converted documents. To ensure the best possible results when converting scanned PDFs to Word, consider the following tips and tricks:

Scanning stage

  • Use a high-quality scanner with a resolution of at least 300 DPI for text-based documents and 600 DPI for documents with images or complex layouts.
  • Ensure the scanner glass is clean and free from smudges or dirt to avoid image quality issues.
  • Align the document properly on the scanner bed to prevent skewed or crooked scans.
  • Use the scanner's automatic document feeder (ADF) for multi-page documents to save time and ensure consistent alignment.
  • Scan in grayscale or black and white for text-based documents to reduce file size. Use color only when necessary.
  • Enable blank page detection to remove any empty pages from the scanned document.
  • Use a scanning app with built-in image enhancement features, such as Office Lens or Adobe Scan, to automatically optimize the scanned image for better OCR results. These apps can correct perspective, adjust contrast, and remove shadows, making the conversion process smoother.

Pre-processing stage

  • Organize and prepare the documents before scanning. Remove staples, paperclips, or sticky notes that may obstruct the text or cause scanning issues.
  • If you need to scan old, fragile documents or photographs, consider using a flatbed scanner with a high resolution (600 DPI or more). Place the document on the scanner glass carefully and use a soft, lint-free cloth to smooth out any creases or folds gently.
  • Use a contrasting background, such as a white sheet of paper, behind the document to help the scanner detect the edges accurately.
  • For delicate or fragile documents, consider using a flatbed scanner instead of an ADF to minimize the risk of damage.

OCR and conversion stage

  • Set up automated ingestion workflow to ensure consistent and efficient processing of large volumes of documents.
  • Choose an OCR solution with high accuracy rates and support for multiple languages, such as Nanonets.
  • Ensure the scanned document is of sufficient quality and resolution for accurate OCR results.
  • Select the appropriate output format (e.g., .docx) and OCR settings (e.g., layout retention, language) based on your requirements.
  • Verify the converted text and make necessary corrections using the OCR software's built-in editing tools.

Post-processing and export stage

  • Review the converted Word document for any formatting inconsistencies or recognition errors.
  • Adjust the document's layout, fonts, and styles to match your preferences or corporate branding guidelines.
  • Use the built-in spell checker and grammar tools in Word to identify and correct any remaining errors.
  • Save the final document in the desired format (e.g., .docx, .pdf) and optimize the file size for storage or sharing.
  • Implement a consistent file naming convention and organize the converted documents in a logical folder structure for easy retrieval. For example, a financial institution could organize converted Word files by client name, document type, and date (e.g., "ClientX_TaxReturn_2023-04-15.docx").
  • Use Zapier integrations to send the converted Word documents directly to your preferred business systems for further processing.
