PDF Scanner: Scan Docs - Lumi

Lumi is the privacy-first PDF Scanner for iPhone. Open the app, point at any document, and Lumi auto-captures, dewarps, and saves a clean scan — all on your device. No accounts. No cloud. No tracking.

WHY PEOPLE CHOOSE LUMI PDF SCANNER

Truly on-device. Unlike every other PDF Scanner you've tried, Lumi has no server. Your scans never leave your iPhone — there's nothing to upload, no account to sign in to, nothing for us to see.

Auto-detect, instantly. Point your camera at a document and Lumi locks on. Hold steady for half a second and the scan happens — no shutter to press, no edges to drag.

Crystal-clear results. Built on Apple's Vision framework, every PDF Scanner result is perspective-corrected (dewarped), exposure-balanced, and sharpened to make text leap off the page.

Smart manual controls. If auto-detect misses, tap the shutter button. Want to scan a screenshot or an old photo? The Photos picker imports any image and Lumi treats it like a fresh scan.

EVERYTHING A MODERN PDF SCANNER SHOULD DO

Multi-page documents — Capture page after page; Lumi groups them into one document and exports a single, sorted PDF. Tap Finish when you're done.

OCR text recognition — Pull selectable, searchable text out of any scan. Works on printed pages, handwriting, and stylized fonts. OCR runs locally with Apple's on-device intelligence — no server, no API calls, no content ever leaves the device.

Live Text everywhere — Open any scan in History. Pinch to zoom, select text directly on the image, copy it, look it up, or translate it. Just like iOS Notes, baked into every Lumi scan.

Merge to one PDF — Pick any number of scans from your History, tap Merge to PDF, and Lumi combines them into a single document, sorted by date, ready to share via the iOS share sheet.

Edit Text — Cover any printed text with a tap-and-drag rectangle and type a replacement. Perfect for fixing a typo, redacting a name, or correcting a misread scan.

Sharp filter for text-heavy pages — Brings the words forward without losing color, like a high-quality photocopy. B&W filter creates a clean monochrome look. Use whichever matches the document.

Crop, Rotate, Mirror — Drag corners to trim black edges. Rotate left, right, or mirror in one tap. Even fix a sideways A4 capture after the fact.

PRIVACY IS THE WHOLE POINT

Most PDF Scanner apps quietly upload your documents to "AI servers" or "cloud OCR services." Lumi doesn't. Camera frames are processed in-memory using Apple's Vision and Core Image. The final JPEG is stored only in Lumi's private sandbox on your iPhone. OCR runs on-device. PDF export happens on-device. The only network calls Lumi ever makes are to Apple's StoreKit, when you choose to subscribe.
