How to work with a image on iPhone (no app to install)
Mobile Safari runs the full Document Scanner in your browser — no App Store download, no upload, no account.
One reason people install third-party apps on their phone is that they don't realise the same tool runs perfectly in mobile browsers. Document Scanner is browser-only — no app store, no install — and it works exactly the same on iPhone as it does on a laptop.
Open the tool: Document Scanner — Browser-only. Nothing is sent to a server.
Step-by-step on iPhone
- Open Safari and go to Document Scanner.
- Tap "Choose file" (or drag from the Files app if you're in split-screen on iPad).
- Pick the image from Photos, iCloud Drive, or Files — they all work.
- Set your options (sizes, quality, output format). Tap "Run" or whatever the equivalent button is for Document Scanner.
- Save the result. Safari downloads to the iCloud Drive Downloads folder by default; tap the result and choose "Save to Files" if you need it somewhere specific.
- AirDrop or share it straight from the Files share menu — useful if the image is going to a Mac next.
Useful iOS-specific tricks
- Add Document Scanner to your home screen to make it feel like a native app: tap the share button in Safari, scroll to "Add to Home Screen." It launches in its own window, no browser chrome.
- Use the Files app for batch input — select multiple images in Files, tap Share → Open in Safari, and Document Scanner picks them all up at once.
- Photos library access works the same as any iOS app, but with no permissions to grant separately.

Why a browser tool beats most native apps for this
Native apps that work with images are almost all just wrappers around browser-class libraries. They usually upload your file to their server, which is slower, less private, and sometimes paywalled. Document Scanner does the work directly in your phone's browser engine — same code path that would run if you were on a desktop, no upload, no signup, no daily limit.
Frequently asked questions
Does it work on older iPhones?
Anything from the last five years handles Document Scanner comfortably. Older devices may take longer for big files, but the underlying APIs (WebAssembly, FileReader) have been stable for years.
Is my image private when I use a browser tool?
Yes — more private than most apps, because nothing is uploaded. The image is processed entirely inside the browser tab and is gone the moment you close it.
Will processing drain my battery?
Heavy image work uses your phone's CPU just like any other intensive app. For most images the job finishes in seconds; a 100MB video might use a noticeable but small slice of battery.
Why isn't there a "Document Scanner" app on the App Store?
Because there doesn't need to be. Mobile browsers run the same WebAssembly the desktop site uses. Shipping a native app would mean maintaining two codebases for the same feature.
