How to use the PDF Summarizer
- Choose a PDF file above (text-based PDFs work best).
- Set the summary length with the slider (10–60% of the original).
- Click Summarize PDF and copy the result. Pro adds GPT-level abstractive summaries.
Tame long PDFs without losing the thread
PDFs are where information goes to hide: hundred-page reports, scanned contracts, research papers with three appendices. A PDF summarizer pulls the signal out so you know what you are dealing with before you commit an afternoon. Use it to triage a stack of papers, to surface the clauses in a contract, to brief yourself on a meeting deck, or to decide whether an ebook is worth the full read.
It pairs naturally with note-taking. Summarize first to get the shape of the document, then read only the sections that matter. That is how busy researchers and founders stay current without reading everything end to end.
Practical tips
- Extract the text first if the PDF is a scan. Image-only files need OCR before any summary is accurate.
- Point the tool at specific sections when you can. A summary of "the pricing section" beats a summary of the whole 80-page doc.
- Verify every number the summary quotes. A misread figure in a contract summary is expensive.
- Combine the summary with your own notes so the key points actually stick.
Frequently asked questions
Is my PDF uploaded anywhere?
No. The file is read in your browser with pdf.js; nothing is sent to a server.
Why does it say 'no extractable text'?
Scanned/image-only PDFs have no text layer. Use an OCR step first, or paste the text into the AI Text Summarizer.
What is an extractive summary?
It keeps the most important existing sentences from the PDF. Abstractive (rewritten) summaries are a Pro feature.
