The free Adobe Scan app turns your device into a powerful portable scanner that recognizes text automatically (OCR). Capture new images with your camera or grab any image from your device. The app converts images to PDF and saves them to Adobe Document Cloud. By default, the app automatically converts image text to real text via optical character recognition (OCR).

Scan features include:

If auto-capture is enabled, simply open the app, wait for the capture, and tap on the thumbnail to view and/or edit your scan.

The scan feature requires access to your camera. If prompted, choose Allow. For details, see Settings.

Note that live edge boundary detection and capture hinting behave differently in auto-capture mode and manual capture mode:

• Auto-capture mode: When the app detects a document, a blue dots identify document corners. The “Capturing… hold steady” hint appears when the app is relatively certain a complete document is in range.

• Manual mode: Simply tap the capture button when ready.

To scan a document:

1. Optional: Optional steps include setting the flash, selecting the document type, and so on.

2. Invoke a scan. The app has two capture modes:

   • By default, auto-capture is enabled, and on startup the app displays the capture screen and tries to detect a document.

   • If auto-capture is disabled, center a document in window and tap the capture button.

3. Follow the on screen hints. The app uses auto crop and image cleaning to improve scan quality. Messages appear on the screen as follows:

   • Looking for document: The app is looking for the document and trying to detect its boundaries.

   • No document found. Capture manually: The app cannot detect the document edges.

4. Edit your scan as described below.

5. Tap Save PDF to automatically convert your scan to a PDF and save to Adobe Document Cloud.

Use the options on the capture screen to control how you scan :

While optional, selecting a document type prior to scanning saves you time later. The document type changes the scan name as well as how the app captures the scan. For example, the app captures the entire camera view for a whiteboard but uses boundary detection when capturing a business card.
