Way 3. Convert Large PDF to Word via Adobe Acrobat

Adobe Acrobat is the leading PDF tool that supports PDF conversion, OCR, editing, compression, and more. It can handle PDFs up to 2GB. When converting a PDF to Word, it will automatically apply OCR to preserve the layout and format well. That’s to say, it’s no problem to convert a scanned PDF to Word.

However, the conversion feature is only available in the Pro version, which means you need to pay an expensive subscription fee. Given the complexity of Adobe, it is more suitable for professionals.

Here is how to use Adobe to convert a large-sized PDF into Word:

  • Open in PDF document in Adobe.
  • Go to the Convert tool.
  • Choose Microsoft Word as the format.
  • Finally, click Convert.

Best For: Professionals needing high-fidelity conversion, large documents, complex layouts, full OCR, and enterprise integration.

Way 4. Convert Large PDF to Word in Microsoft Word

Microsoft Word can open PDFs and convert them to editable documents. If your computer has installed this software, then this is a readily available solution at hand. However, it lacks an OCR feature and cannot handle scanned or PDF documents with complex layouts.

For a digital PDF, layout is retained; for a scanned one, you’ll get plain extracted text with formatting loss. Therefore, Microsoft Word is a better choice for a text-based PDF.

Steps to export a long PDF to Word in MS Word:

  • In Word, go to File > Open and select your PDF.

Select File

  • Click OK on the pop-up messages.

Click OK

  • Wait for a while and save the document.

Best For: Ideal for editing PDFs created in Word, but not for scanned documents or complex layouts.
