PDF Highlight Extractor

Stop Manual Copy-Pasting Forever

We've all been there: you finish reading a groundbreaking book or a dense academic paper, and your highlights are scattered across hundreds of pages. Re-reading the whole document to find them is inefficient.

Our PDF Highlight Extractor solves this by aggregating every highlighted passage into a single, structured document. It preserves the color coding (e.g., Yellow for main ideas, Blue for supporting evidence), allowing you to maintain the semantic meaning of your notes.

Ideal for Research and Study

Students: Quickly summarize textbooks for exam prep. Turn a 300-page book into a 5-page cheat sheet.
Researchers: Collect quotes and citations for your thesis or literature review. Export to CSV to manage qualitative coding.
Kindle Users: Clean up the messy PDF exports from your e-reader and import them into your digital brain.

Don't let your reading effort go to waste. Extract your highlights and make them actionable.

Frequently Asked Questions

Can it detect different highlight colors?

Yes. We capture the RGB color values, allowing you to filter or categorize notes (e.g., 'Only show Red highlights').

What about scanned books?

The PDF must have a selectable text layer (OCR). If it's just an image, you'll need to OCR it first.

Can I export to Excel?

Yes, select the CSV format. It works perfectly with Excel, Google Sheets, and Apple Numbers.
