Native text plus local OCR
Text is extracted on device first. Only low-text pages use the completed OCR engine, and the result reports exactly how many pages required recognition.
Verified on-device AI
Summarize long PDFs without sharing their text.
Summarize native or scanned PDF text while document content and generation remain in your browser. Choose Quick, Standard, Bullets, or Detailed output, review the summary and key points, regenerate if needed, then copy or export both views as TXT. A disclosed English model must be installed with consent, and generated summaries can omit, distort, or overstate important details.

Local document
Extract native text and OCR scanned pages
Native extraction runs first. Pages without usable text reuse the completed local OCR engine and are reported separately.

Grounded local result
Summary and key points
Your local summary will appear here
Every non-empty section is summarized before consolidation. Quick mode is shorter; Detailed keeps page-range sections.
Verify important details in the original PDF
AI output can omit or distort nuance, figures, tables, qualifications, and legal meaning. OCR mistakes can propagate into the summary. This is an aid, not an authoritative interpretation.
Check the local model, then choose a PDF to begin.
Every section before consolidation
PdfEditorOnlineFree summarizes bounded page-aware sections before producing the final view, reducing the prefix-only failure common to long document prompts.
Measurable, reusable output
Compare word counts, reading time, reduction, text pages, and OCR pages. Regenerate another style from retained local text, copy a view, or export both views as TXT.
One-time model setup
Know what downloads before it starts.
1. Review the local model
See the 343.5 MiB executable size, English scope, Apache-2.0 license, immutable revision, hashes, storage, memory, and removal guidance.
2. Give explicit consent
No model request starts on page load. Consent begins the pinned public asset download and integrity check.
3. Process the PDF locally
PDF bytes, extracted text, OCR text, prompts, section summaries, and final output stay inside this browser tab.
4. Remove or reuse
Verified assets can be reused offline from browser cache or removed from the workspace whenever you choose.
