6 Best Scanner Apps for Android (2026)

Quick Verdict

Your phone's camera is a document scanner — the app decides how good the result is:

• Adobe Scan — the best all-round free pick: no watermark, no ads, best image cleanup.
• Genius Scan — the highest-rated scanner (4.9 stars): no watermark, works offline, on-device privacy.
• CamScanner — the feature king: batch scanning, tags, fax, but watermarked free exports with ads.
• Microsoft OneDrive — the Lens replacement: scanning built into Microsoft's cloud app.
• Clear Scan — the free OCR specialist: multi-page text recognition with no daily cap.
• Tiny Scanner — the lightweight veteran: small, fast, one-time $4.99 upgrade.

Before You Install Anything

Most Android phones already scan documents. The Google Drive app has a scan button that drops a PDF straight into Drive, and Files by Google added its own scanner back in 2023 — both free, no extra install. For the occasional one-page receipt, that's all you need. A dedicated app only earns its place when you scan often: batch pages, OCR (optical character recognition — turning the photo into selectable text), organize by tags, or export without a watermark.

Also worth knowing: Microsoft Lens is gone. Microsoft discontinued it on February 9, 2026 and pulled it from the Play Store. If a blog still recommends Lens, it's outdated — the scanner now lives inside the OneDrive app.

Comparison Table

1. Adobe Scan — Best All-Round Free Pick

Adobe Scan is the safest recommendation for most people. It's free to install, carries no "Contains ads" label on its Play listing, and adds no watermark to exports — the two things that make free CamScanner annoying. Its Sensei-powered cleanup detects document borders, removes shadows, corrects perspective, and sharpens text, so a photo taken at an angle under office light comes out looking like a flatbed scan.

The listing confirms: OCR capacity rises from 5 to 100 pages on the paid tier — basic text recognition is free, longer documents are where it asks you to pay. Newer additions include a Magic eraser (removes fingers, stains, creases in one tap) and AI-generated document summaries, genuinely useful for long contracts you don't want to read in full. The trade-offs: you need an Adobe account for cloud sync, its data-safety card says data may be shared with third parties, and serious PDF editing (merge, convert) sits behind the ~$9.99/month Acrobat Premium.

Download Adobe Scan on Google Play

Best for: everyone who wants a free, clean scan without a watermark. Price: free.

2. Genius Scan — Highest Rated, Most Private

Genius Scan holds the highest rating in the category: 4.9 stars from over 600,000 Play reviews. Its free tier is unusually generous — no watermark, no ads label, no scan limit — and its listing describes on-device document processing, which means your scans are processed on your phone rather than uploaded to a server by default. For legal, medical, or financial documents, that privacy-first design is the point.

Features include batch scanning, document detection with background removal, shadow removal, document merging and splitting, biometric app lock, PDF encryption, tags, and OCR with searchable-PDF creation. Export goes to Drive, Dropbox, OneDrive, Box, or WebDAV. The paid Plus tier (~$7.99) adds OCR limits lifted, cloud auto-export, and SmartDocument merging — free covers scanning and clean exports. The learning curve is slightly steeper than Adobe's, but the rating suggests people figure it out.

Download Genius Scan on Google Play

Best for: sensitive documents and power organizers. Price: free; Plus from ~$7.99.

3. CamScanner — Most Features, Most Friction

CamScanner is the most-installed scanner app on Earth: 500M+ installs, 4.6 stars from over 5 million reviews. Nothing else packs this much in — batch scanning, auto-capture, document color presets, tags, OCR search inside your library, annotations, password-protected viewing, wireless printing, fax to 30+ countries, and sync across phone, tablet, and web. If you scan dozens of documents a week, the feature depth is real.

The free tier is where it stings. Every export carries a CamScanner watermark until you pay, the listing carries the "Contains ads" label, free users see interstitials between scans, and most text recognition sits in the paid tier (in-app purchases $0.49–$399.99). The trust history: a 2019 malware-laced ad library got it pulled from Play; it was cleaned and reinstated that September, and no credible research has found malware since. The 2026 concern is different — its privacy policy says scan data can be stored on servers in China, and its data-safety card says data may be shared with third parties. By default your scans sync to its cloud; for anything private, turn sync off or export straight to your own Drive.

Download CamScanner on Google Play

Best for: high-volume scanning teams. Price: free with ads and watermark; subscription to remove.

4. Microsoft OneDrive — Where Lens's Scanner Lives Now

If you were a Microsoft Lens user, this is your chapter. With Lens retired, the OneDrive app's built-in scanner is Microsoft's official replacement: scan, sign, and mark up documents right in the app, and everything lands in OneDrive with files encrypted at rest and in transit. Its listing shows 4.6 stars from over 7 million reviews and no "Contains ads" label.

One honest note: Lens's direct export to Word, PowerPoint, and OneNote didn't fully carry over — OneDrive's scanner is simpler. If you relied on that workflow, Adobe Scan or Genius Scan are closer replacements. OneDrive is the pick when you already live in Microsoft 365: scans sit next to your Office files, and 5GB of storage is free (Microsoft 365 Personal starts at $6.99/month in the US for 1TB).

Download Microsoft OneDrive on Google Play

Best for: Microsoft 365 users. Price: free (5GB); Microsoft 365 from $6.99/mo.

5. Clear Scan — Best Free OCR

Clear Scanner's headline feature is free OCR with no daily cap. Where CamScanner gates multi-page text recognition behind its paid tier and Adobe Scan caps free OCR at 5 pages, Clear Scanner runs OCR across multi-page documents at no cost, exporting to PDF, JPEG, or TXT — with no sign-in required.

Beyond OCR: automatic edge detection, perspective correction, brightness and shadow adjustment, filters (document, photo, black & white), folders and subfolders, page reordering, Letter/Legal/A4 page sizes, backup and restore, and a tiny app size. The trade-off is the business model: the free tier is ad-supported with banners and occasional interstitials, and the interface is functional rather than polished. A one-time ~$3.99 Pro upgrade removes the ads — no subscription.

Download Clear Scan on Google Play

Best for: extracting text from scans for free. Price: free with ads; ~$3.99 one-time Pro.

6. Tiny Scanner — Lightweight and Fast

Tiny Scanner has been around for over a decade with millions of users, and its pitch hasn't changed: quick scan to PDF, nothing wasted. The listing describes AI-powered border detection, batch scanning, signing tools, OCR text recognition, PDF-to-Word/Excel conversion, folder encryption, and cloud sync.

It shines on older phones where heavier apps stutter — the APK stays small and responsive. The free tier is ad-supported; the Pro upgrade is a one-time ~$4.99, not a subscription, which reviewers compare favorably against CamScanner's recurring pricing. OCR is more basic than the top picks, and cloud sync means linking Dropbox, Drive, or Box manually. If you want a small local scanner with no subscription and don't mind paying once to remove ads, this is the veteran pick.

Download Tiny Scanner on Google Play

Best for: older phones and subscription-haters. Price: free with ads; ~$4.99 one-time Pro.

How to Choose in 60 Seconds

• Just want a good free scan? → Adobe Scan.
• Scanning something private? → Genius Scan (on-device processing).
• Scanning in bulk with tags and fax? → CamScanner (paid).
• Living in Microsoft 365? → OneDrive's scanner.
• Need free OCR on many pages? → Clear Scan.
• Old phone, no subscription? → Tiny Scanner.

And the technique advice every reviewer repeats: good scans are 80% photography. Use natural daylight, keep the page flat, wipe your camera lens, and pick the highest quality setting in the app. A free app with good lighting beats a paid app in a dim room.
