QuickOne Scanner: PDF & OCR
Scan, Sign & Convert to PDF
Free · Designed for iPad. Not verified for macOS.
Simple, Fast offline scanner. Import, merge, sign, and tag documents with notes, searchable OCR, PDF export.
Your documents never leave your iPhone.
QuickOne Scanner turns your camera into a document scanner that works entirely on your device. Edge detection, image cleanup, text recognition and search all run locally. There is no account to create, no server to upload to, and nothing for anyone to leak.
WHAT MAKES IT DIFFERENT
• Everything on-device. Your scans, page images and recognized text stay in the app's private storage. We operate no server and receive nothing.
• Genuinely free. No subscription, no one-time unlock, no scan allowance, no ads. Not "free for your first 5 scans" — free.
• No watermark. Not on any export, not ever.
• No account. No email, no phone number, no sign-in.
• The camera is used only to scan a page. Nothing else is asked for, and photo import uses the system picker, which needs no library access.
SCAN
• Automatic page detection — hold your iPhone over the page and the edges are found for you
• Multiple pages in one session, with retake and reorder
• Import photos you already have
• Add pages to an existing document whenever you like
• Reorder pages by dragging, crop any page, delete the ones you do not want
• Original, Grayscale and Black & white filters — always reversible, because the untouched original is never overwritten
READ
• On-device text recognition for Latin scripts and for Chinese, Simplified and Traditional
• The script is detected automatically; you can override it for one document or for the whole app
• Re-read your entire library with a different model at any time
• Copy the recognized text, or save it as a .txt file
FIND
• Full-text search across document titles and every word the recognition read inside your pages
• Chinese is indexed character by character, so partial queries work
• Type # to filter by tag, and combine tags to narrow further
ORGANISE
• Tags that pick their own icon from what they mean — money, ID, health, legal, home
• Seventeen built-in tags, plus any you invent
• Automatic tag suggestions from the recognized text, worked out on your device — remove any that do not fit
• Folders, colour-coded from their names
MARK UP
• Sign a page with your finger, in five ink colours
• Sticky notes with your own background and text colour, including a transparent background for a plain caption
• Drag, resize and place anything where you want it
• Export an annotated PDF that keeps your marks
SHARE AND EXPORT
• PDF with an invisible searchable text layer, so other apps can search your scan
• PDF, images only, when the smallest file is what matters
• JPEG, one per page
• Plain .txt of the recognized text
• Export your whole library, a single folder, or everything under one tag as a ZIP you keep yourself
BUILT FOR iPHONE AND iPAD
• Light, dark, or follow the system
• English, Français, Español, 简体中文, 繁體中文
• iOS 15.5 and newer
ONE THING WORTH KNOWING
Because nothing is uploaded, your scans exist only on this device. If you lose it or reset it, they are gone with it. Settings → Export library as ZIP keeps a copy wherever you choose. Signatures and notes are kept until you close the app — share the annotated PDF to keep them.
PRIVACY
QuickOne Scanner adds no analytics, no advertising and no tracking SDK of any kind. The capture screen is Apple's own document camera, built into iOS. Both text-recognition models are built into the app itself, so OCR works offline from the very first scan — even on a device that has never been online.
