How to OCR a PDF and Create a New PDF from the OCR Text

How to ensure your PDF is machine readable for PDF2Anki to read your PDF and generate cards from it.

Optical Character Recognition (OCR) is a vital process for converting images of text within PDF documents into editable and searchable text. This step-by-step guide will walk you through OCR'ing a PDF and then creating a new PDF from the OCR text, ensuring compatibility with programs like PDF2Anki that require text-based PDF files for flashcard generation

Step 1: Choose an OCR Software

First, you need to select an OCR software. There are many options available, both free and paid, such as Adobe Acrobat, ABBYY FineReader, and online services like OnlineOCR. For this guide, we'll assume you use a generic OCR tool that handles PDF inputs and outputs.

Step 2: OCR the PDF

  1. Open the OCR Software: Launch your chosen OCR software or navigate to an online OCR service.

  2. Upload Your PDF: Look for an option to "Upload" or "Open" a PDF file and select the PDF document you want to OCR.

  3. Select OCR Language: If prompted, select the language of the text within your PDF. This ensures higher accuracy in text recognition.

  4. Start the OCR Process: Look for an option to start the OCR process. This might be labelled "Recognize Text," "Start OCR," "Convert," or something similar.

  5. Review and Edit: After the OCR process is complete, some tools allow you to review and edit the recognized text. This step is crucial for ensuring accuracy, especially with documents containing complex formatting or various fonts.

  6. Save or Export: Once you're satisfied with the OCR text, save or export the document. Ensure you choose an option to save it as a PDF to maintain compatibility with PDF2Anki.

Step 3: Create a New PDF from the OCR Text

After OCR'ing the document, you should now have a text-based PDF. However, if your OCR tool directly exports to a text file (.txt) or if you need to further edit the OCR text, follow these steps to create a new PDF:

  1. Open a Document Editor: Use a document editor like Microsoft Word, Google Docs, or another text editor that can export documents as PDFs.

  2. Insert the OCR Text: Copy and paste the OCR text into the document editor. You can also use the "Import" or "Open" feature if you're working with a text file.

  3. Format the Text: Apply any necessary formatting to ensure the document is readable and organized. This might include adjusting font sizes, and styles, and adding headings or bullet points.

  4. Export as PDF: Once your document is properly formatted, look for an option to "Export" or "Save As" and select PDF as the output format. Name your file appropriately and choose a save location.

Step 4: Import the New PDF into PDF2Anki

With your new, text-based PDF file ready, you can now import it into PDF2Anki for flashcard generation. The process involves:

  1. Access PDF2Anki: Open PDF2Anki and upload a deck by Dashboard > New Deck

  2. Upload the New PDF: Select the option to upload or import a PDF file and choose the PDF you created from the OCR text.

  3. Generate Flashcards: Select your desired flashcard type within PDF2Anki to generate flashcards from your newly OCR'd and formatted PDF.

By following these steps, you convert a non-text PDF into a text-based format suitable for flashcard generation, ensuring no valuable information is lost due to format incompatibility.
