Summarize a PDF
Read the main points of a long PDF in a minute.
Or drop a PDF here. Files stay on this device. Nothing is uploaded.
The summary is made on your device in one of two ways: key sentences picked from the document itself, which works in every browser and offline, or a written summary from the AI model built into your browser, where one is available. The text of your document is never sent to a server.
How to summarize a PDF
- Choose the PDF to summarize.
- Read the key sentences, each with the page it came from, and set how many you want.
- If your browser has a built-in AI model, choose Written summary to have it write one on your device.
- Select Copy or Download to keep the summary.
What you get
Key sentences, always available
The most representative sentences are picked from the document and shown unchanged, with a link to their page. No AI model is involved and it works offline.
A written summary where the browser can
Browsers with a built-in Summarizer (currently Chrome on desktop) can write a short summary or a list of key points with an on-device model.
Nothing leaves your device
Both kinds of summary are computed locally. There is no server and no account.
Clear when something is missing
If the browser has no built-in model, the tool says so and shows the key sentences instead.
Summarize PDF: questions and answers
Is the summary written by AI?
Only if you choose the written summary and your browser has a built-in model. The default is extractive: it selects sentences from your document without rewriting them.
Why is the written summary not offered in my browser?
It uses the Summarizer API built into the browser, which currently ships in Chrome 138 and later on desktop computers. The browser downloads its model once; after that it works offline.
Can it summarize a scanned PDF?
A scan has no text until it is recognised. Run text recognition (OCR) first, then summarize.
Is my document sent to a server?
No. The text is read and summarized in your browser.
