Frequently Asked Questions

Is the PDF Summary Generator free?

Yes. Summary Generator is completely free to use, with no sign-up or account required.

Are my files uploaded to a server?

No. The whole summary runs entirely in your browser — your PDF is never uploaded anywhere, and no external service is called.

Does this use AI or an LLM?

No. This is an extractive summary built on a transparent, browser-native scoring algorithm: it ranks sentences by word frequency and document position, then keeps the most representative ones in their original order. No text is rewritten, and no facts are invented — every sentence in the summary appears verbatim in the source PDF.

Does it work with a scanned PDF (no selectable text)?

No. This tool needs real extracted text to build a summary. If your PDF is a scanned image with no text layer, run it through OCR PDF first to get a text layer, then summarize that output.

Why is the summary shorter/longer than I expected?

The Short/Medium/Long selector picks an approximate fraction of the document's total sentences (roughly 10% / 20% / 35%). Very short documents will produce very short summaries, because there are fewer sentences available to pick from.

What's the difference between 'Key points' and 'Full summary'?

Both contain the same picked sentences — Key points presents them as a bulleted list, Full summary joins them into one flowing paragraph for easier copy-paste or download.

Can I save the summary?

Yes. You can copy the summary to your clipboard with the Copy button, or download it as a plain-text file that includes both the key points and the full summary, plus the word/sentence counts for reference.
