The 3-second scanner. Open ZipScan and the camera is already pointing at your document. It captures automatically, cleans up the page, and hands you a searchable PDF ready to share — before other apps finish loading. WHY ZIPSCAN • Instant by design — the app opens straight into the camera, so scanning starts before you've tapped anything. • Import from Photos — a photo of a page becomes a searchable PDF, same pipeline as the camera. Share to ZipScan straight from the Photos share sheet. • Your text is yours — Copy Text hands you the recognized words; export as PDF or JPEG; reorder, remove, or add pages anytime. • Sign and mark up — the system Markup tools, with your saved signatures, right on the PDF. • Searchable PDFs, always — on-device OCR embeds real text in every scan, so you can search inside your documents in Files, Mail, or any PDF reader. • Smart names — scans name themselves after what's on the page ("Hashi Market – Aug 13"), not "Scan_0142.pdf". • Small files — a full page is usually a few hundred KB, not several MB. Email-friendly, always. • Multi-page in one pass — keep pointing at pages; they stack into one PDF. PRIVATE BY ARCHITECTURE Everything happens on your iPhone. No account. No cloud. No tracking. Your documents never leave your device unless YOU share them. Scan in airplane mode if you like — it all works. HONEST PRICING 10 free scans every month — full quality, full OCR, no watermark, forever. Need more? One purchase unlocks unlimited scans for life. Prefer monthly? There's a small monthly plan, cancel anytime. No forced trials, no bait-and-switch, no features held hostage. BUILT INTO iOS • Lock Screen widget — scan without unlocking • Control Center button — swap your flashlight for a scanner • Action Button support (iPhone 15 Pro and later) • Siri & Shortcuts — "Scan a document with ZipScan" • Back Tap — double-tap your phone to scan WHAT ZIPSCAN DOESN'T DO No ads.
