Do Scan
The Most Private PDF Scanner & OCR App for iPhone & iPad — Scan, Sign, Edit & Convert PDFs Entirely Offline
Your Documents. Your Device. No Exceptions. Ever.
Do Scan transforms your iPhone and iPad into the most powerful, most private document scanner and PDF toolkit on the App Store. Snap a photo of any document — a contract, a receipt, a textbook page, a handwritten note — and watch it instantly become a crystal-clear, fully searchable PDF. No blurry edges. No washed-out text. No compromises.
Unlike every other scanner app on the market, Do Scan makes you a promise that no competitor can match: your documents never leave your device. There is no cloud. There is no server. There is no account. There is no login screen. There is no analytics. There is no telemetry. There is literally no network code in the entire application. We couldn't see your documents even if we wanted to — because we built it that way on purpose.
And the best part? You pay once. That's it. No $9.99/month. No $39.99/year. No "premium tier" unlock. No "free trial" that auto-renews into a subscription you forgot about. One single payment and Do Scan is yours — forever. Every feature. Every update. No strings attached.

How Do Scan Works — In Seconds
Do Scan was engineered from the ground up for speed and simplicity. There's no onboarding flow, no tutorial screens, no account creation, no email verification. You open the app and you're scanning. Here's how effortlessly it works:
- Open & Scan — Launch Do Scan and point your camera at any document. The app's intelligent edge detection instantly identifies the document boundaries, highlights them in real-time, and captures a perfectly cropped, perspective-corrected image in milliseconds.
- Automatic OCR Processing — The moment a page is captured, Apple's on-device text recognition engine kicks in. Every word, every number, every character is recognized and embedded into the PDF — making it instantly searchable, selectable, and copyable.
- Edit, Sign & Annotate — Add your digital signature, highlight key passages, draw annotations with Apple Pencil, reorder pages, merge with other documents, or compress the file for easy sharing via email or AirDrop.
- Save & Organize — Your finished PDF is saved locally on your device. Mark favorites, search your entire library by the actual text content inside your documents, and find anything in seconds.
The entire process — from opening your camera to having a fully searchable, signed, annotated PDF — takes less time than it took you to read this paragraph.
Scan Like an Absolute Pro
Do Scan's scanning engine is built on Apple's Vision framework — the same technology that powers the most advanced image processing on the planet. Every scan looks like it came from a $500 flatbed scanner, not a phone camera. Whether you're scanning a crumpled receipt in a dimly lit restaurant or a multi-page legal contract on your office desk, the results are consistently stunning.
- Intelligent Real-Time Edge Detection — The camera automatically identifies document boundaries in real-time, even on cluttered backgrounds. No manual cropping. No misaligned edges.
- Automatic Perspective & Keystoning Correction — Shoot at any angle and Do Scan mathematically corrects the perspective distortion, producing a perfectly flat, straight document every single time.
- Multi-Page Batch Scanning — Capture an entire stack of documents — 5 pages, 50 pages, 500 pages — in a single scanning session without ever leaving the camera. Perfect for digitizing entire filing cabinets.
- Adaptive Color Filters — Switch between Full Color, Grayscale, and Black & White modes. Re-apply filters at any time after scanning — your original capture is always preserved.
- Razor-Sharp Text Optimization — Advanced image processing sharpens text and fine print to produce output that's cleaner and more readable than the original document.
- Low-Light Performance — Optimized for real-world conditions where lighting isn't perfect. Do Scan compensates for shadows, uneven lighting, and low contrast automatically.
The Most Powerful On-Device OCR Available
Most scanner apps either skip OCR entirely or send your documents to a remote server for processing — meaning your private contracts, medical records, and financial statements pass through someone else's cloud. Do Scan does something radically different: it runs Apple's most advanced text recognition engine entirely on your device's neural engine. Zero network. Zero latency. Zero privacy risk.
- Automatic Text Recognition on Every Page — OCR runs instantly on every scanned page. You don't have to enable it, configure it, or wait for it. It just works.
- True Searchable PDFs — The recognized text is embedded as an invisible layer behind the scanned image, creating a true searchable PDF. Select text, copy it, paste it into emails, search within the document — exactly like a born-digital PDF.
- Full-Library Content Search — Search across your entire document library by the actual words inside your scans. Type "invoice" and instantly find every receipt, bill, and statement that contains that word — across hundreds of documents.
- Smart Auto-Title Suggestions — Do Scan reads the first page of every document and intelligently suggests a title based on the content. No more "Scan_20260627_143522.pdf" — your documents are named meaningfully without you lifting a finger.
- Multi-Language Recognition — Leveraging Apple's built-in language models, Do Scan recognizes text in multiple languages without any additional downloads or configuration.
A Complete PDF Editor That Replaces Your Desktop Software
Forget paying for Adobe Acrobat or any other bloated desktop PDF editor. Do Scan packs an incredibly comprehensive PDF editing suite right into your pocket. Every tool you need to work with documents professionally is right here — and it all runs on your iPhone or iPad without ever touching the internet.
- Full Annotation & Markup Suite — Highlight important passages in multiple colors, underline key phrases, draw freehand annotations, add text boxes, and mark up documents exactly the way you need. Full Apple Pencil support on iPad for handwriting-precise annotations.
- Legally-Ready Digital Signatures — Create your signature once — draw it with your finger or Apple Pencil — and instantly drop it onto any document, any page, any position. Resize and reposition freely. Your signature is saved securely on-device for instant reuse across every document you'll ever sign.
- Visual Page Editor — See thumbnail previews of every page. Drag to reorder. Tap to rotate. Swipe to delete. Insert pages from other documents. Building the perfect PDF has never been this intuitive.
- Unlimited Document Merging — Combine any number of PDFs, scans, and imported files into a single unified document. Merge a scanned contract with imported appendices, combine meeting notes from different days, or consolidate receipts into one expense report.
- Intelligent 3-Tier Compression — Choose from Small, Medium, or Large compression levels. Small files are perfect for email attachments with strict size limits. Large preserves maximum image quality. Medium strikes the ideal balance for most use cases.
- Military-Grade Password Protection — Lock sensitive PDFs with strong encryption. Tax documents, medical records, legal contracts — protect anything that shouldn't be viewed without authorization.
- PDF/A Archival Conversion — Convert any document to PDF/A, the ISO-standardized format designed for long-term preservation. Guaranteed to render identically 10, 50, or 100 years from now. Essential for legal compliance, government submissions, and permanent recordkeeping.

Why Do Scan Destroys the Competition
Let's be brutally honest about the scanner app market: it's a subscription trap. The most popular scanner apps lock basic features behind recurring paywalls, upload your documents to their servers, and charge you $20–$40 every single year for the privilege of scanning your own paperwork. Do Scan was built as the antidote to all of that.
- No Subscription — Ever — Competitors charge $9.99/month or $39.99/year. Over 5 years, that's $200. Do Scan is a single payment of $14.99. You save over $185 in the first 5 years alone — and it only gets better from there.
- No Cloud Upload — Most scanner apps upload your documents to their servers for "sync" and "backup." That means your tax returns, medical records, contracts, and personal letters live on someone else's computer. Do Scan has no server. Period.
- No Account or Login — No email address. No password. No "Sign in with Apple." No "Create your free account." You open the app and you're scanning. Zero friction.
- No Third-Party Code — Do Scan is built entirely on Apple's native frameworks. No Firebase. No Google Analytics. No Facebook SDK. No Mixpanel. No Amplitude. No Sentry. No third-party libraries of any kind. Your data touches Apple's code and our code — nothing else exists in the binary.
- No Ads — Ever — No banner ads. No interstitials. No "watch a video to unlock this feature." No sponsored content. The app is ad-free because you paid for it, and that's how it should work.
- No Feature Gating — Every feature is unlocked from day one. OCR, signatures, merging, compression, PDF/A, password protection — everything. There's no "Pro" tier. There's no "Premium." You get everything.
Privacy Is Not a Feature — It's the Foundation
In an era where most apps treat your personal data as their product, Do Scan takes a radically different approach. Privacy isn't a checkbox on a marketing page — it's the architectural foundation that every single line of code was built upon. Here's what that means in practice:
- Zero Network Code — The app contains no networking libraries, no HTTP clients, no WebSocket connections, no URL sessions. It is physically incapable of transmitting data off your device because the code to do so simply does not exist.
- Zero Analytics & Telemetry — No Firebase. No Google Analytics. No Mixpanel. No Amplitude. No crash reporting services. We have absolutely no idea how you use the app, how often you open it, or what you scan. And that's by design.
- Zero Third-Party SDKs — The entire app is built using Apple's own frameworks: UIKit, Vision, PDFKit, PencilKit, CoreImage. No third-party dependency graph. No supply chain risk. No hidden data collection buried in a framework you've never heard of.
- Apple-Verified Privacy Manifest — Do Scan ships with a PrivacyInfo.xcprivacy manifest declaring exactly which system APIs are accessed and why. The only APIs used are UserDefaults (for saving your preferences) and File Timestamps (for sorting documents). Neither transmits data.
- App Store Nutrition Label: "Data Not Collected" — Apple's App Privacy section confirms it: Do Scan collects no data from you. Not "data not linked to you." Not "data used to track you." Literally: Data. Not. Collected.
Read the complete privacy policy — it's the shortest privacy policy you'll ever read, because there's genuinely nothing to disclose.
What Early Users Are Saying
Built Entirely on Apple's Native Frameworks
Do Scan isn't a cross-platform app ported from Android. It isn't a web wrapper disguised as a native app. It's a true, purpose-built iOS and iPadOS application written from scratch using Apple's own native technologies. This means it's faster, smoother, more power-efficient, and more deeply integrated with your device than any competitor built with React Native, Flutter, or Electron.
- Vision Framework — Apple's most advanced computer vision engine powers the edge detection, perspective correction, and OCR text recognition.
- PDFKit — Apple's native PDF rendering and editing framework ensures pixel-perfect PDF creation and manipulation.
- PencilKit — Full Apple Pencil integration for pressure-sensitive annotations, handwriting, and signatures with zero latency.
- CoreImage — Hardware-accelerated image processing for filters, sharpening, and color correction that runs at 60fps on the device's GPU.
- UIKit & SwiftUI — Native UI frameworks that deliver smooth 120Hz animations, proper Dynamic Type support, VoiceOver accessibility, and deep system integration.
The result is an app that feels like it was made by Apple themselves — because it's built with the exact same tools Apple uses.

Frequently Asked Questions About Do Scan
Does Do Scan require an internet connection to work?
Absolutely not. Do Scan works 100% offline. There is no server, no cloud sync, no background uploads, and no network access whatsoever. You can use every single feature — scanning, OCR, signing, merging, compression, conversion — on an airplane, in a basement, in the middle of nowhere. The app literally contains no networking code.
Is Do Scan a subscription or a one-time purchase?
Do Scan is a one-time purchase. You pay once and own it forever — no recurring charges, no annual renewal, no in-app purchases to unlock features, no "premium tier." Every feature is included from day one and every future update is free. Compare that to competitors who charge $20–$40 per year.
How private is Do Scan really? Do you collect any data at all?
Do Scan collects absolutely zero data. No analytics, no crash reporting, no usage telemetry, no tracking, no advertising IDs. We have no servers, no databases, and no ability to see anything you do in the app. The App Store privacy label confirms: "Data Not Collected." Read our full privacy policy — it's refreshingly short.
Does OCR text recognition work offline?
Yes — OCR runs entirely on your device's neural engine using Apple's built-in Vision framework. There is no cloud processing involved. Text recognition happens instantly as each page is captured, and the results are embedded directly into the PDF. No internet required, no delays, no data upload.
Can I import and edit existing PDFs from other apps?
Yes. Import PDFs from Files, email, Safari, or any other app via the iOS share sheet. Once imported, you can annotate, sign, reorder pages, merge with other documents, compress, password-protect, and convert to PDF/A. Do Scan handles PDFs from any source.
Does Do Scan work on iPad with Apple Pencil?
Absolutely. Do Scan is a universal app with a layout optimized specifically for iPad's larger display. Apple Pencil support is fully integrated — use it for pressure-sensitive annotations, precise markup, and natural handwriting signatures. Split View and Slide Over multitasking are fully supported.
What file formats can Do Scan convert to PDF?
Do Scan converts Microsoft Word (.doc, .docx), PowerPoint (.ppt, .pptx), photos (JPEG, PNG, HEIC), RTF, TXT, and HTML files to PDF. It can also convert any document to PDF/A for long-term archival. All conversion happens locally on your device.
How does Do Scan compare to CamScanner, Adobe Scan, or Genius Scan?
Unlike CamScanner ($49.99/year), Adobe Scan ($9.99/month), and Genius Scan ($29.99/year), Do Scan is a one-time purchase with zero subscription fees. Unlike all three, Do Scan collects absolutely no data and works completely offline. No cloud, no account, no third-party SDKs. You get every feature from day one for a fraction of what competitors charge in a single year.
Can I password-protect my scanned documents?
Yes. Do Scan lets you apply strong password encryption to any PDF. Without the password, the file cannot be opened. Perfect for tax documents, medical records, legal contracts, financial statements, and any other sensitive documents that require access control.
What is PDF/A and why should I care?
PDF/A is an ISO-standardized format specifically designed for long-term archival. Unlike regular PDFs, PDF/A files are self-contained and guaranteed to render identically on any device, in any software, decades from now. It's required by many governments and legal systems for official document submission. Do Scan can convert any document to PDF/A with one tap.
How many pages can I scan in one session?
There is no limit. Scan 1 page or 1,000 pages in a single session. Do Scan's batch scanning mode lets you capture page after page without leaving the camera view. The only limit is your device's storage space.
Is Do Scan available for Android?
Currently, Do Scan is available exclusively for iPhone and iPad (iOS and iPadOS). It's built entirely on Apple's native frameworks, which is what makes it so fast, private, and deeply integrated with iOS. An Android version may be considered in the future.
