How does the PDF Vocabulary Extractor work?

Our tool analyzes your PDF document, extracts all unique words, filters out common words, and organizes them by frequency. You can then select which words to include in your custom vocabulary list.

Is my PDF content secure?

Yes! All processing happens in your browser. Your PDF is never uploaded to our servers, ensuring complete privacy for your documents.

What languages does this tool support?

Currently, the tool works best with English language PDFs. We're working to add support for additional languages in future updates.

Can I use this for academic research?

Absolutely! Many students and researchers use our tool to analyze texts and build specialized vocabulary lists for their studies.

Why are some common words still appearing?

Our common words filter isn't perfect. You can use the "Advanced only" difficulty setting or increase the minimum word length to filter out more simple words.

What's the maximum PDF size I can process?

The tool can handle PDFs up to 20MB. For best performance with large documents, we recommend splitting them into smaller sections.

How can I use the exported word lists?

The CSV files can be imported into flashcard apps like Anki or Quizlet, used to create study guides, or analyzed for word frequency patterns.
