How to Scan Documents on Android — 5 Best Methods 2026

Modern Android phones have cameras good enough to produce clean, professional document scans. With the right app, your phone replaces a physical scanner entirely and produces PDFs you can share directly. Here are the five best methods — including which one handles multiple pages cleanly and which to use when the document is sensitive.

Method 1 — Google Drive (Built-In, No Install Needed)

Google Drive is pre-installed on virtually all Android phones. It includes a hidden document scanner:

1. Open the Google Drive app
2. Tap the + button (bottom right)
3. Tap Scan
4. Point your camera at the document — Drive auto-detects edges and captures the crop
5. Tap the checkmark to accept, or retake
6. Tap + (bottom left) to add more pages to the same PDF
7. Tap the save icon (top right) → name your file → Save

The file saves directly to Google Drive as a PDF with OCR (text searchable). No extra app download required.

Best for: Google Workspace users, quick scans where you want the result in Drive immediately.

Privacy note: Scans go to your Google Drive account. Google holds encryption keys and can access file contents.

Method 2 — Microsoft Lens (Best Overall)

Microsoft Lens (formerly Office Lens) is the most capable free scanner for Android. Download from the Play Store — no Microsoft account required for basic use.

1. Open Microsoft Lens
2. Select mode: Document, Whiteboard, Business Card, or Photo
3. Hold the phone above the document — Lens detects edges automatically and shows a blue border
4. Tap the shutter button to capture
5. Tap + (Add) to scan additional pages into the same document
6. Tap Done when all pages are captured
7. Tap PDF as the export format → Save
8. Choose to save locally or to OneDrive/SharePoint

Standout features: Perspective correction (fixes angled shots), whiteboard mode (removes glare and shadows from whiteboard photos), automatic page detection across multi-page captures, strong OCR, and the ability to save directly as Word, PowerPoint, or PDF.

Best for: Professional document scanning, whiteboards, business cards, multi-page documents.

Method 3 — Samsung Built-In (Samsung Devices Only)

Samsung phones (Galaxy S/A/Note series) include a document scanner built directly into the camera and Samsung Notes:

Via Samsung Camera:

1. Open the Camera app
2. Swipe to More modes
3. Tap Expert RAW or look for Document scan depending on your model

Via Samsung Notes:

1. Open Samsung Notes
2. Tap + to create a new note
3. Tap the attachment icon (paperclip) → Add scan
4. Scan the document; tap Save to embed in the note or export as PDF

Best for: Samsung users who want completely native functionality without a third-party app.

Method 4 — Adobe Scan (Best OCR Quality)

Adobe Scan produces the highest quality OCR text recognition of any free scanner app. Requires an Adobe account (free).

1. Download Adobe Scan from the Play Store, sign in with a free Adobe account
2. Point at the document — the app auto-detects edges and captures automatically (no shutter tap needed)
3. Tap + to add more pages
4. Tap the thumbnail (bottom right) to review → Save PDF
5. PDF is saved to Adobe Document Cloud and downloaded locally

Best for: Legal documents, contracts, anything that needs OCR-accurate text for searching or editing later.

Privacy note: Scans upload to Adobe Document Cloud (no zero-knowledge encryption).

Method 5 — Camera + FileShot PDF Tool (For Privacy-Sensitive Documents)

When a scanned document is sensitive — medical records, legal contracts, tax returns — uploading it to Google Drive or Adobe Cloud means a corporation can read it. A better workflow:

1. Scan with Microsoft Lens and choose save to phone (not OneDrive)
2. Open FileShot's PDF tool in your mobile browser
3. Merge or annotate the scanned PDF if needed
4. Upload via FileShot: the file is encrypted in your browser with AES-256-GCM before it leaves your phone — the server never sees the decrypted content
5. Share the encrypted link; set it to expire after N downloads or a time period

This workflow keeps the scanned document encrypted in transit and at rest, with the decryption key in the URL fragment that only you and the recipient see.

Tips for a Clean Scan

• Lighting: Natural daylight gives the cleanest results. Avoid direct overhead light that causes glare on glossy paper.
• Background contrast: Scan white paper on a dark surface — apps detect edges better with high contrast.
• Hold steady: Most apps capture automatically when you hold still. Don't press a shutter button while moving — let the auto-capture trigger.
• Flatten the page: For bound documents, press the spine down or use a book scanner stand. Curved pages introduce perspective distortion that degrades OCR accuracy.
• Use Document mode, not Photo mode: Document mode applies perspective correction and contrast enhancement automatically.
