Document scanning: definition and issues in 2026
Document scanning refers to the process of converting a physical document (contract, invoice, archive, form) into a usable digital file. It covers two distinct levels: simple image scanning (scan to PDF or JPG) and scanning with character recognition (OCR), which makes the document content indexable and editable.
In 2026, scanning has become a legal and organisational necessity for many businesses. In France, the Essoc law of 2018 allows the destruction of paper originals after scanning under strict conditions, and the decree of 24 December 2022 extended the e-invoicing obligation for VAT-registered businesses.
Why scan documents?
- Reduction in physical storage costs: one linear metre of archives represents approximately 2,000 documents and costs between €15 and €40/year in storage.
- Instant access and search: a document scanned with OCR can be found in seconds via full-text search.
- Security and backup: the risk of loss from disaster (fire, flood) is eliminated through digital duplication.
- Regulatory compliance: certain sectors (banking, insurance, healthcare) have legal obligations for the digital retention of documents.
Adobe Scan and Microsoft Lens: the best free mobile apps
Adobe Scan
Adobe Scan is the most complete mobile scanning app available free of charge on iOS and Android. It features automatic perspective correction, document edge detection, real-time OCR, and direct export to Adobe Acrobat. Scanned documents are stored in Adobe Document Cloud and accessible from all devices.
The app is completely free for standard individual use. Advanced features (PDF editing, electronic signature, collaboration) require an Adobe Acrobat subscription (€23.99/month).
Microsoft Lens
Microsoft Lens stands out through its native integration with the Microsoft 365 suite. A scanned document can be exported directly as a PDF, Word document, PowerPoint presentation, or OneNote note. The app also offers a whiteboard mode for scanning presentations and diagrams. Microsoft Lens is free and available on iOS, Android, and Windows.
For Microsoft 365 users, this is the most coherent option in terms of digital ecosystem.
Google Drive scan
The scan function of the Google Drive app allows a document to be scanned directly as a PDF with built-in OCR. The file is automatically saved to Google Drive, facilitating sharing and collaboration. This solution is particularly suited to Google Workspace users.
CamScanner Pro and advanced mobile apps
CamScanner is one of the most downloaded mobile scanning apps in the world, with over 500 million installations. The free version is limited (watermarks on exports, restricted storage). The Pro version, available at €4.99/month or €35/year, removes limitations and adds batch processing features, advanced OCR, and electronic signature.
CamScanner is particularly suited to mobile professionals (sales representatives, consultants) who regularly scan large numbers of documents from their smartphone.

ABBYY FineReader Standard is available from €69/year on subscription.
The software is particularly suited to legal, notarial, and accounting professions that process large volumes of contractual or administrative documents.

Frequently asked questions
What is the best app for scanning documents?
In 2026, Adobe Scan is the reference for mobile scanning thanks to its built-in OCR, automatic perspective correction, and integration with Adobe Acrobat. Microsoft Lens is recommended for Office 365 users (direct export to Word or PowerPoint). Google Drive scan suits Google users who want a simple and free solution. For heavy use, CamScanner Pro (€4.99/month) offers advanced batch processing features.
What is the difference between scanning and OCR?
Scanning converts a paper document into a digital image (JPG, PNG, image PDF). OCR (Optical Character Recognition) goes further by analysing the image to extract the text, making the document searchable and editable. The main scanning apps (Adobe Scan, Microsoft Lens, ABBYY FineReader) include OCR, allowing you to search within the text of the scanned document.
How do I scan documents in bulk for a business?
For high-volume scanning, several solutions exist: a desktop multifunction scanner (from €300 for a professional model), a document management system like Zeendoc from around €150/month, or an external scanning service provider like Iron Mountain or Numen for historical archives. The choice depends on volume, frequency and confidentiality requirements.
Are document scanning services GDPR compliant?
Professional document scanning services (Zeendoc, Iron Mountain, Numen) offer GDPR compliance guarantees with data storage on European territory, data encryption in transit and at rest, and data processing agreements (DPA). Consumer mobile apps (Adobe Scan, Microsoft Lens) store data in US cloud infrastructure. For sensitive documents, French or European DMS solutions are recommended.
