## What is ScanNgai?

Scan, sign, send — all in one app, and all free.

ScanNgai is made for people who send documents from their phone every week: ID cards, house registrations, receipts and application forms. A few taps and your file is ready to send.

• Auto scanning – finds the page edges, crops and straightens for you, and scans many pages in a row
• Crisp black-and-white photocopy filter, or a colour-copy look
• Certified copies – add a "for ... only #" line, your signature and the date to every page. Your signature is remembered for next time
• ID card copies – cards at real size on A4, two per page, ready to print
• Hide private details – draw black bars over anything you don't want to share before sending
• Crop, rotate, reorder and delete pages
• Photos to PDF – pick several photos, in the order you tap them, and combine them into one PDF
• PDF to JPG – export only the pages you need
• Add pages to a PDF – from the camera, Photos or another PDF
• Choose the file size – small for messaging, normal, or sharp for printing
• Share straight to LINE, Mail or AirDrop
• iPhone and iPad, synced through your own iCloud Drive
• In English and Thai

Your documents stay yours
No sign-up, and your documents are never uploaded to anyone's server. Your files stay on your device or in your own iCloud Drive.

Free, with everything included
No watermark and no subscription – kept free by small ads that never get in the way of scanning.
