Scanbox: PDF Scanner + OCR

Scanbox turns your phone into a fast, private document scanner - and every step of it happens on your device, not in someone else's cloud.

AUTOMATIC EDGE DETECTION
Point your camera at any document and Scanbox finds the edges and corrects the perspective automatically, so a photo taken at an angle still comes out looking flat and scanned.

ON-DEVICE OCR, FOUR LANGUAGES
Text recognition runs entirely on your phone in Korean, English, Japanese, and Chinese. Extract and search the text inside your scans without sending a single image anywhere.

SEARCHABLE PDF, NO WATERMARK
Export a searchable PDF, JPEG, or PNG whenever you're done - and it comes out clean. Standard exports are never stamped with a watermark, unlike most scanner apps.

FULL-LIBRARY TEXT SEARCH
Search across your entire scan library by the text inside the documents, not just filenames - so a receipt from three months ago turns up the moment you remember one word on it.

CROP, ROTATE, ENHANCE
Fine-tune every page after capture: crop tighter, rotate to fix orientation, and enhance contrast so faded receipts and dim whiteboard photos become easy to read.

SHARE ANYWHERE
Send finished PDFs through the system share sheet to email, messaging apps, cloud storage, or a printer - wherever you actually need the document to go.

BUILT FOR PRIVACY
There's no account, no cloud upload, and no server processing your images. Capture, OCR, and PDF creation all happen locally, and your documents never leave your phone unless you choose to share them.

FREQUENTLY ASKED QUESTIONS

Is OCR and searchable PDF export really included at no extra cost?
Yes. Text recognition, searchable PDF export, and watermark-clean exports all come standard - none of it is locked behind Pro. Pro adds convenience features on top, not the core scanning and search functions.

Does anything ever get uploaded to a server?
No. Capture, edge detection, OCR, and PDF generation all run on your device. Scanbox has no server component processing your documents, and there's no account to create.

What languages does the text recognition support?
On-device OCR currently covers Korean, English, Japanese, and Chinese, with more languages planned as the underlying recognition models improve.

Can I organize scans into folders?
Basic scanning keeps everything in one library, searchable by content. Pro adds folder organization so you can group scans by client, project, or year as your library grows.

Does batch scanning work for long documents?
Yes. Fast batch scanning captures page after page in one continuous flow instead of returning to a menu between shots, which makes multi-page contracts, reports, and booklets far quicker to get through.

Can I lock a PDF so only I can open it?
Yes, with Pro. Set a password on export and the resulting PDF requires that password to open in any reader, useful for tax documents, IDs, or anything you'd rather keep sealed if a device is lost.

Will Scanbox work without an internet connection?
Yes. Capture, edge detection, OCR, and PDF creation are all local operations, so scanning works exactly the same on a plane or in a basement with no signal at all.

What does Pro unlock?
A single one-time purchase unlocks fast batch scanning for multi-page documents, adds folder organization, lets you password-protect PDFs, and enables advanced export options for quality, page size, and compression. No subscription, ever.

SCANBOX PRO
One purchase, forever: fast batch scanning, folders to organize your library, password-protected PDFs, and advanced export controls. Perfect for receipts, contracts, ID documents, whiteboards, notes, and anything you'd rather not upload to a cloud scanner.
