From paper to PDF in four steps

No flatbed scanner, no cables. Just your phone and PrimeDocu.

Open PrimeDocu and tap Scan

Open the app or web version, tap the Scan button, and point your camera at any document — receipt, contract, ID, handwritten note.

Auto edge detection fires

PrimeDocu detects the document edges in real time, highlights them, and automatically corrects perspective — even if you're shooting at an angle.

Enhance and multi-page

Apply contrast enhancement for better readability. Add more pages to the same PDF — scan a full contract in one session.

Everything a mobile scanner should do

Built for the documents you deal with every day.

Auto edge detection

Corners are detected automatically in real time. No manual cropping — the scanner finds the document for you.

Perspective correction

Angled or skewed shots are straightened automatically. Get a flat, professional-looking scan every time.

Multi-page PDF

Scan multiple pages in one session. PrimeDocu merges them into a single ordered PDF document automatically.

Image enhancement

Automatic contrast and brightness adjustment makes text sharp and backgrounds clean — even from low-light photos.

Encrypted immediately

Your scan is encrypted with AES-256-GCM on-device the moment it is captured. Nobody else can see your documents.

Import from gallery

Already took a photo? Import it from your gallery or file system — the same edge detection and enhancement is applied.

Frequently asked questions

Does the scanner work without a camera?

Yes. You can import existing photos from your phone gallery or file system. The same edge detection and perspective correction is applied to imported images as to live camera shots.

What file format does it produce?

The scanner outputs a high-resolution PDF by default. Individual pages can also be exported as JPEG or PNG if needed.

Can I scan multiple pages into one PDF?

Yes. Scan as many pages as you need in one session. PrimeDocu automatically combines them into a single, ordered multi-page PDF.

Are scanned documents secure?

Yes. Every scanned document is encrypted using AES-256-GCM on your device before upload. The encryption key is stored in your device's secure enclave and never sent to our servers.

Is it as good as a dedicated flatbed scanner?

For most everyday documents — receipts, contracts, notes, IDs — yes. For archival or legal-quality scans where absolute precision is required, a dedicated flatbed scanner may be more appropriate.
