Best pdf document summarizer to generate accurate summary from PDF

Summarizing a very large PDF (over 1500 pages) is a challenging task, especially with free PDF document summarizer tool. Currently, Microsoft tools like Word or Edge do not have a dedicated, built-in PDF document summarization feature that can handle such large documents directly.

1. Microsoft Word
You can open the PDF directly in Word (Word 2016 or later):

• File > Open > select your PDF.
• Word will convert the PDF into an editable document.
• This process might be resource-intensive for very large PDFs.

Once converted, you can:

• Use Word's Outline view (View > Outline) to see main headings.
• Manually identify key sections.
• Use Summarize features (though limited) or Smart Lookup for key ideas.

Note: About the PDF document summarizer. Word's built-in summarization features are minimal and not fully automated.

2. Microsoft Edge

• Open your PDF in Microsoft Edge.
• Use Highlight and Notes to mark important parts, then manually extract summaries.
• No automatic summarization here, but useful for manual review.
