# How to Summarize a PDF on iPhone and Android

You received a PDF on your phone and need the gist before a meeting. The quickest method works on any iPhone or Android with no app to install: open a PDF summarizer in your browser and upload the file from Files, Mail or WhatsApp.

## Key facts

- No app needed: open pdf-summarize.com in Safari or Chrome, tap the upload zone, pick the PDF.
- Works with PDFs saved in Files, Google Drive, iCloud Drive, Downloads, or received by email and messaging apps (save them first).
- Built-in assistants can summarize selected text or a whole document on some recent devices, but features vary by model, OS version, app and region.
- Photos of documents: use your phone's document scanner to create a clean PDF first.
- Results can be copied or shared straight into a message.

## Summarize a PDF in your phone's browser

1. **Save the PDF on your phone** — From Mail or a messaging app, tap the file → Share → Save to Files (iPhone) or Download (Android).
2. **Open pdf-summarize.com** — In Safari, Chrome or any mobile browser. No account, nothing to install.
3. **Tap the upload zone** — Choose Browse / Files and select the PDF.
4. **Pick what you need** — Summary, key points, questions or text, and tap the button.
5. **Copy or share the result** — Use Copy, then paste into WhatsApp, Mail or Notes.

## On iPhone

- **Files app**: PDFs from Mail, Safari and messaging apps can be saved here, then picked in the browser upload dialog.
- **Scanning paper**: in the Notes app or the Files app, use “Scan Documents” to create a flat, cropped PDF — far better for OCR than a regular photo.
- **Built-in writing tools**: on supported recent iPhones, Apple's system writing tools can summarize text you select in many apps. They're handy for an email-length passage; for a long PDF, a dedicated tool that reads every page and cites them is more practical.

## On Android

- **Downloads / Files by Google**: PDFs you download are available in the browser's file picker.
- **Scanning paper**: Google Drive's scan feature (and many manufacturers' camera apps) produce clean PDFs.
- **Built-in assistants**: depending on your phone, Google's assistant or the manufacturer's AI features may summarize on-screen content or documents. Availability varies by device, language and region.

> **On your phone right now?** — Open this page, tap the upload zone and pick your PDF.

## Tips for mobile

- **Wi-Fi for large files** — PDFs up to 20 MB are accepted, but uploads are faster on Wi-Fi.
- **Ask short questions** — the chat works well on small screens: “What's the deadline?”, “How much?”.
- **Key points mode** fits a phone screen better than a long summary.
- **Download as .md or .txt** to keep the result in your notes app.
