Adobe Scan Tradeoffs
Why people still choose it:
- Built-in OCR for ID text extraction — Adobe Scan's OCR layer can extract printed text from ID cards — names, dates, ID numbers. For workflows that need typed data from scanned IDs, Adobe's text recognition adds a useful automation layer.
- Established mobile scanning experience — Adobe Scan has years of refinement on iOS and Android. The camera interface, auto-capture, and enhancement filters are polished and reliable on mobile devices.
Why people are switching away:
- Cloud upload for OCR: ID images are uploaded to Adobe's cloud for text recognition. For scanning passports, driver's licenses, and government IDs, uploading to a third-party server is a legitimate privacy concern.
- App install required: iOS or Android app required. No browser option. If you need to scan an ID from a laptop or locked-down device, Adobe Scan isn't available.
- Adobe account mandatory: Must create and sign into an Adobe account before scanning. MiOffice AI requires no account — open the URL and scan.
- OCR limits on free: 25 OCR scans per month on free. After that, text recognition requires Acrobat Pro at $9.99/month.
Detailed Reviews
1. Adobe Scan — Polished Mobile ID Scanner (With Cloud OCR)
How It Works
Adobe Scan (Adobe Inc., San Jose) captures ID documents with automatic edge detection, perspective correction, and optional OCR. Point your phone at a driver's license, passport, or ID card, and the app detects the card edges, crops and straightens the image, and enhances text clarity. OCR can extract printed text fields (name, date of birth, ID number) into selectable text. Scans sync to Adobe Document Cloud.
Our Test Results
Auto-crop accuracy was excellent on ID cards — correctly detecting edges on 19 of 20 test documents, including passport pages with holographic overlays. Color accuracy was the best in our test, preserving the exact colors of ID photos and security features. Text clarity was sharp on all printed fields. OCR correctly extracted name and date fields from 16 of 20 documents.
The concerns for ID scanning specifically: all images upload to Adobe's cloud for OCR processing. For passport and government ID scanning, cloud upload is a significant privacy consideration. Free OCR is capped at 25 scans per month. Mobile-only — no laptop webcam option.
Technical Details
- Engine: Adobe Sensei AI for edge detection, cloud OCR for text extraction
- Processing: On-device capture + cloud OCR (images uploaded for text recognition)
- Output: PDF with OCR text layer, JPG
- Resolution: High-res output using device camera maximum
- Privacy: ID images uploaded to Adobe cloud for OCR
- Compliance: GDPR, SOC 2, enterprise BAA
- ✓ Best color accuracy in our test — preserves ID photo and security feature colors
- ✓ OCR extracts name, date, and ID number fields
- ✓ Excellent auto-crop accuracy (19/20 test documents)
- ✓ Clean perspective correction on angled captures
- ✗ ID images uploaded to cloud for OCR — privacy concern for government IDs
- ✗ Mobile-only — no browser or desktop option
- ✗ Adobe account required before first scan

2. MiOffice AI — Best Free Browser-Based ID Scanner
How It Works
MiOffice AI scans ID documents directly in your browser using WebAssembly — point your camera at a driver's license, passport, or ID card, and the auto-crop detects the document boundary. Perspective correction straightens angled captures, and the result exports as a high-resolution PDF, JPG, or PNG. The entire process runs locally on your device — particularly important for sensitive identity documents. No app install, no account, no cloud upload.
Technical Specs
- Engine: WASM-based edge detection and perspective correction running in-browser
- Output: PDF, JPG, PNG with high-resolution output (full device camera resolution)
- Processing: In-browser via WebAssembly — ID images are processed on your device

3. Microsoft Lens — Free and Functional (Mobile Only)
How It Works
Microsoft Lens (Microsoft Corp., Redmond) offers a Document capture mode that works for ID cards and similar small documents. The app detects edges, crops, and straightens the image. Export options include PDF, Word, and direct save to OneDrive. Processing is on-device for basic capture, with cloud processing for OCR and format conversion.
Our Test Results
Edge detection worked reliably on standard-size ID cards (17 of 20 correct). Passport pages with complex backgrounds were more challenging — edge detection missed boundaries on 3 documents. Color accuracy was acceptable but slightly muted compared to Adobe Scan. Text clarity was good on printed fields. The Document mode isn't specifically optimized for IDs, which showed in edge cases.
The advantage: completely free with no limits. For occasional ID scanning without needing specialized features, Microsoft Lens gets the job done. The drawback: no ID-specific features like front+back merge or field extraction.
Technical Details
- Engine: Microsoft AI for edge detection, cloud OCR
- Processing: On-device capture, cloud for OCR
- Output: PDF, Word, PowerPoint, JPG
- Resolution: Medium-high resolution output
- Privacy: Cloud processing for OCR and format conversion
- Compliance: GDPR, ISO 27001
- ✓ Completely free with no usage limits
- ✓ Reliable edge detection on standard ID cards
- ✓ Export to Word and OneDrive for office workflows
- ✓ No account required for basic scanning
- ✗ Mobile-only — no browser version
- ✗ No ID-specific scanning mode — uses generic Document mode
- ✗ Edge detection struggles with passport pages
- ✗ Cloud-dependent for OCR and Office exports
- ✗ Color accuracy slightly muted compared to competitors
4. CamScanner — Feature-Rich but Cloud-Dependent
How It Works
CamScanner (INTSIG Information Co., Shanghai) handles ID scanning through its general document scanner. The app captures the ID, applies edge detection and perspective correction, and offers multiple enhancement filters (Auto, Magic Color, Gray, B&W). The ID Card mode on Premium combines front and back into a single page. All processing happens on CamScanner's cloud servers.
Our Test Results
Edge detection was adequate on standard ID cards (16 of 20 correct) but struggled with rounded-corner cards and transparent overlay features common on modern IDs. Enhancement filters helped improve text readability on some documents. The ID Card mode on Premium (front+back on one page) was convenient for applications requiring both sides.
The concerns remain significant for ID scanning: all images are processed on cloud servers, the app's 2019 security incident is relevant context for identity document handling, and free scans are watermarked. For sensitive ID documents, cloud processing adds unnecessary risk.
Technical Details
- Engine: Cloud-based scanning and OCR (INTSIG servers)
- Processing: All processing on CamScanner cloud servers
- Output: PDF, JPG (watermarked on free)
- Resolution: Medium-high resolution
- Privacy: ID images uploaded to cloud servers for processing
- Compliance: GDPR (stated)
- ✓ ID Card mode combines front + back on one page (Premium)
- ✓ Multiple enhancement filters for readability
- ✓ Cross-platform with web app access
- ✓ Large user base with established workflow
- ✗ All ID images uploaded to cloud servers — privacy concern
- ✗ Free tier watermarks scans of sensitive ID documents
- ✗ Past security incident (2019) relevant for identity documents
- ✗ Edge detection weaker on modern cards with rounded corners
- ✗ Account required — adds friction for quick ID scans
5. SwiftScan — Fast Mobile Scanner (Limited Free Tier)
How It Works
SwiftScan (Maple Media, US) is a mobile scanner with on-device processing for basic capture. The app detects document edges, crops, and applies perspective correction. OCR and advanced export features require the $3/month Pro subscription. Processing stays on-device for basic scanning — cloud is optional for sync and advanced features.
Our Test Results
Basic capture was fast (1-2 seconds) and reliable on standard ID cards (16 of 20 correct). Color accuracy was good, preserving ID photo colors well. Perspective correction handled moderate angles but introduced minor distortion at steeper angles. The free tier exports to JPG only — PDF export requires Pro.
At $3/month, SwiftScan Pro is one of the more affordable paid options. But the free tier is quite limited — JPG-only export without OCR means you're essentially getting a camera with auto-crop. For ID scanning specifically, the lack of front+back merge on free is a notable gap.
Technical Details
- Engine: On-device image processing (basic), cloud for OCR (Pro)
- Processing: On-device for capture and crop, cloud for OCR features
- Output: JPG (free), PDF/Word/Excel (Pro)
- Resolution: High-res using device camera
- Privacy: On-device for basic capture, cloud for Pro OCR features
- Compliance: GDPR
- ✓ Fast on-device capture (1-2 seconds)
- ✓ Good color accuracy — preserves ID photo colors
- ✓ Affordable Pro tier at $3/month
- ✓ On-device processing for basic scanning
- ✗ Mobile-only — no browser version
- ✗ Free tier limited to JPG export — no PDF output
- ✗ No front+back ID merge on free tier
- ✗ OCR requires Pro subscription ($3/mo)
- ✗ Perspective correction introduces distortion at steep angles
- ✗ Limited enhancement options on free tier
