OKEN

OKEN is a document scanner app that turns your Android device into a portable document management system. Capture high-quality scans of IDs, passports, contracts, receipts, and any physical document using just your phone's camera—then store them digitally without the clutter.

Scanning is straightforward. Select your document type, frame it in good light, and tap to capture. The app automatically converts your photo into a crisp, high-quality scan in seconds. Save in PDF, JPG, Word, or TXT format depending on your needs. Build a searchable archive on your device, organized by document type.

Store scans locally or move them to the cloud. Sign up to unlock a free Premium account with 10 GB of cloud storage—no credit card required. This means your critical documents are backed up safely and accessible from anywhere, not just on your phone. Whether you're traveling, managing finances, or handling legal paperwork, your documents stay with you.

Beyond basic scanning, this app includes powerful PDF tools in the Tools tab. Watermark documents to protect them, merge multiple PDFs into a single file, lock PDFs with passwords, and rearrange pages without external software. You can also compress text files and create image collages from your scans. These features work entirely within the app, making document management faster than juggling multiple tools.

No registration is required to start scanning, though creating an account unlocks cloud backup and removes ads. The app runs on Android 6.0 and later, supporting most phones and tablets released in the past several years. Scans are saved locally first, giving you full control over what you store and when.

If you regularly carry sensitive documents—passport copies, insurance papers, medical records, contracts, or IDs—this app eliminates the need for physical copies. It's especially useful for travelers, remote workers, and anyone managing multiple documents. OKEN keeps everything organized, secure, and instantly available.
