Best for: Privacy-conscious iPhone users who want native workflows and a capable free download
ScanLens processes scanning on-device using iPhone hardware rather than a remote document-processing pipeline. Free to download: document, ID, and passport scanning, filters, and PDF / JPG / PNG export. Plans include OCR in 14 languages, interactive text extraction, e-signatures, merge and split PDFs, searchable PDFs, watermark removal, cloud sync, app lock, and workflows.
Strengths: On-device privacy, offline capture, iPhone-specific workflow, lifetime option
Weaknesses: iOS only, OCR and the full PDF toolkit are on paid plans
Best for: Cross-platform users, established workflow
CamScanner is one of the oldest and most popular scanner apps with 700M+ downloads. Good edge detection and document enhancement. However, documents are processed on Chinese servers, which may concern privacy-focused users. Had malware incident in 2019 (since resolved). Free tier has ads; premium removes them and adds features.
Strengths: Established, cross-platform, large user community
Weaknesses: Privacy concerns, ads in free tier, subscription required for full features
Best for: Adobe ecosystem users, business document workflow
Adobe Scan integrates directly with Adobe Acrobat and Document Cloud. Excellent OCR quality for printed text. Clean interface with good enhancement options. Free tier is capable for basic use; subscription unlocks advanced PDF editing and larger cloud storage.
Strengths: Adobe integration, excellent printed text OCR, professional features
Weaknesses: Expensive subscription ($9.99/mo), cloud-dependent, limited free OCR exports
OneDrive includes a document scanner and is Microsoft's official recommendation. It is the closest fit for a Microsoft-centered workflow, but Microsoft states that its scanner cannot save scans locally on the device. Microsoft Support.
Direct answer: Microsoft ended support on February 9, 2026, and disabled new scans after March 9. Keep Lens installed and stay signed in until you have verified and copied every scan you need.
Best for: Occasional scanning, maximum simplicity
Built into every iPhone, Notes scanner is dead simple. No app to download, no account needed. Basic edge detection, perspective correction, and PDF saving. Uses Live Text for some OCR functionality. Limited features but perfectly adequate for occasional use.
Strengths: Built-in, completely free, simple, on-device processing
Weaknesses: No handwriting OCR, limited export options, basic features only
Choose: ScanLens or Apple Notes
Both process documents entirely on-device. Your tax returns, medical records, and legal documents never touch external servers. ScanLens offers more features; Notes is simpler.
Choose: Adobe Scan
If you're already in the Adobe ecosystem with Acrobat and Document Cloud, Adobe Scan integrates directly. The subscription is expensive, but it may be included in existing Adobe plans.
OneDrive includes a document scanner and is Microsoft's official recommendation. It is the closest fit for a Microsoft-centered workflow, but Microsoft states that its scanner cannot save scans locally on the device. Microsoft Support.
Choose: ScanLens or Apple Notes
ScanLens gives students a more complete capture workflow — scanning, filters, folders, and PDF / JPG / PNG export — while Apple Notes is the simplest fully free option. If you need OCR for notes and handwriting, factor paid-plan pricing into the decision.
Choose: CamScanner or ScanLens
CamScanner works on Android, iOS, and web. ScanLens exports to any cloud service, making it compatible with cross-platform teams even though the app itself is iOS-only.
Compare ScanLens and Apple Notes first. ScanLens is a dedicated scanner — document, ID, and passport capture, filters, folders, search, and PDF / JPG / PNG export come with the free download; Plans add OCR, cloud sync, e-signatures, and the PDF toolkit. Apple Notes is fully free but is a notes app first, with a much more limited scan flow.
CamScanner is generally safe for personal use. Past security concerns (a 2019 malware incident affecting the free version on Google Play) have been addressed. However, documents are processed on their servers, which may not be suitable for sensitive business or legal documents. Consider on-device alternatives like ScanLens for privacy-sensitive scanning.
Microsoft recommends the OneDrive scanner. Apple Notes and Files work for basic scanning, while ScanLens is an option for local PDFs, on-device OCR, and additional PDF tools.
Apple Notes has basic scanning built-in and is completely free with on-device processing. However, it lacks advanced features like batch scanning optimization, handwriting OCR, granular PDF export controls, and sophisticated document organization. For occasional scanning, Notes works well; for regular use, dedicated apps offer better efficiency.
Download ScanLens and test the workflow yourself. Free scanning, filters, folders, and PDF / JPG / PNG export come with the app. Plans include OCR in 14 languages, interactive text extraction, e-signatures, merge and split PDFs, searchable PDFs, watermark removal, cloud sync, app lock, and workflows.
