Guide

PDF Summary Online — Key Sentences from Your File

Pull the most repeated, central sentences out of a long PDF so you can decide what deserves a full read. This runs on PdfPeaks servers. It highlights sentences that are already in the file — it does not write a new analysis.

How It Works

Upload

Prefer PDFs with selectable text (OCR scans first if needed).

Highlight

The server ranks sentences from the extracted text.

Verify

Check figures, dates, and critical clauses against the source PDF.

Security & Privacy

Summaries are built on our servers from sentences in the extracted text. Translation runs on our servers when an offline language pair is installed; otherwise extracted text may go to a free translation service to finish the job. Text is not used to train models and is deleted after the job TTL — see our privacy details.

Common Use Cases

  • Research: Screen long papers before deep reading.
  • Business: Brief stakeholders on vendor proposals and RFPs.
  • Legal overview: High-level contract section maps (not legal advice).
  • Students: Build study guides from chapter PDFs.
  • Support: Skim technical manual updates quickly.

Tips for Best Results

AI summaries can miss nuance — never rely on them alone for legal, medical, or financial decisions. Pair with Translate PDF for non-English sources, or Extract Text when you need the full plain text.
