Paperline: Offline PDF Scanner

Tired of a scanner that wants a subscription, a card number or an account before it will save a PDF?

Paperline is the other kind of scanner app. You photograph a page, it finds the edges, flattens the perspective, cleans up the shadows and reads the text. All of it happens on your phone. The app has no server of its own: nothing is uploaded unless you choose to share a file.

WHY PEOPLE LEAVE OTHER SCANNERS
• A free trial that quietly turns into a yearly charge
• Ads in the middle of a simple job
• Features that used to be free, moved behind a paywall
• A forced account and cloud storage for a few pages
Paperline does none of that. There is no account, no cloud, no ads, no watermark and no analytics.

WHAT YOU GET
• Live automatic edge detection through the camera. Hold the phone steady and the page is captured by itself, or tap the shutter
• Import photos from your gallery, or use Share to Paperline from any app
• Crop with draggable corners and edges, plus a magnifier loupe for precise placement
• Perspective correction that straightens pages shot at an angle
• Filters: Enhanced (removes shadows), Color, Grayscale, Black & white, Original
• Rotate pages, add pages, re-edit any page later
• Multi-page documents: reorder pages with long-press and drag, delete pages
• Text recognition (OCR) on the device for English, Polish, German, French, Spanish and other languages written in the Latin alphabet
• Copy the recognised text, or search across all your documents by the words inside them
• New documents get a useful name from their text, like "2026-10-30 Invoice Northwind Studio"
• Export a searchable PDF in A4, Letter or fit-to-page size, with an invisible text layer so you can search and copy in any PDF viewer
• Pick full quality or a smaller file for email, and put both sides of an ID card on one A4 page at real size
• Export as JPG, share through the share sheet, save to Downloads/Paperline or to any folder you pick (Syncthing, Nextcloud, SD card)
• Save every document as a PDF to Downloads or your chosen folder in one tap, for your own backups
• Clean, modern design with light and dark themes

PAY ONCE
Try everything free for 7 days. No card needed, and nothing can charge you, because the trial is not a subscription. After 7 days, a single one-time purchase unlocks scanning new pages for good. The price is shown in Google Play in your currency.
• One payment, no subscription, nothing renews, nothing to cancel
• Every feature is included. Nothing gets moved to a paid tier later
• If you never buy, your existing documents stay open, searchable and exportable. Your scans are never held hostage

PRIVACY
• No account and no sign-in
• Scans live only in the app's private storage on your phone. Backups of the app data are turned off
• Text recognition (Google ML Kit) runs on the device, and its diagnostics upload is removed from the app
• The camera is used only to scan documents
• The only network connection is Google Play: your purchase, app updates and the optional rating prompt
• Scanning and text recognition run on the device. Only the purchase, updates and the rating prompt go through Google Play

Delete a document and its pages are removed from the phone. Uninstall the app and everything it stored goes with it.
