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).

Scanning: Quick steps

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.


Scanning from the capture window

To scan a document:

  1. Optional: configure flash settings, select the document type, and so on.

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

    • image By default, auto-capture is enabled, and on startup the app displays the capture screen and tries to detect a document.
    • image 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.
    • Capturing… hold steady: Edge detection can see the entire document.
    • 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.

Optional steps
