Lina Scanner: PDF Scanner, OCR

Lina Scanner — the premium on-device document scanner that finishes the job in one shot Receipts, contracts, notes, business cards, whiteboards, any paper. Point your camera and Lina Scanner turns it into a cropped, sharpened, searchable document. Cropping, filters, OCR, search, and privacy protection all run entirely on your device, offline. No ads, no sign-up, no cloud upload. Automatic edge detection and perspective correction Finds a document's four corners automatically and straightens a tilted photo into a clean rectangle, like a real scanner. Adjust corners yourself if needed, or keep the full frame uncropped. Auto-crop applies instantly in burst mode. Nine color filters built for documents Document B&W (erases shadows), Magic (fixes uneven lighting), Sharpen, Brighten, Whiten, Warm, Cool, Gray, and Original. A dim, shadowy photo turns into a crisp document. Remove or reapply filters any time, with no damage to the original. On-device OCR and full-text search Recognizes Korean, English, Spanish, and Japanese. Pick up to 2 languages at once for mixed-language documents. Every scan is indexed on your device for instant search, and text exports as a searchable, selectable PDF. Runs automatically right after capture. Automatic personal-info detection and masking Sensitive numbers like ID, phone, and card numbers are detected in recognized text and hidden automatically. The viewer covers them with a reversible blur; exporting applies a permanent mask. Toggle visibility per document any time. Automatic blur and duplicate detection Out-of-focus shots and accidental double-captures are flagged automatically. Review everything in Tools and clean up only what you don't need. Clean, folder-based organization Sort documents into folders, and jump back to frequent ones with Favorites and Recent. Drag to reorder pages and folders, merge folders, or duplicate one entirely. Pinch the grid to adjust columns. Flexible export options Export as a regular PDF, a searchable PDF, a plain TXT file, or straight to your photo library in JPG or PNG. Choose whether crop, filter, and masking apply on each export, build your own filename template, and let large documents auto-split into parts. A full toolkit for managing documents Instantly recognize QR codes and barcodes in a photo, clean up duplicate pages, and keep deleted items in Trash for a period you choose. Exported PDFs and TXTs land in their own vault. A thoughtfully polished experience Burst-captured pages process automatically in the background, in capture order, and the app slows or pauses briefly if your device gets hot, protecting battery and lifespan. Dark mode, resolution, haptics, and grid columns are all yours to tune, and an in-app guide explains how each feature works. An intuitive, lightweight interface Built with no bloated ads or decoration, so capturing, organizing, and exporting take the fewest taps possible. Long-press to multi-select pages, and drag once to reorder. Single shots and burst mode Single-shot for one quick page, or burst mode for a multi-page contract or notebook. Four resolution tiers balance quality against file size. Storage at a glance See exactly how much space originals, cache, exported files, and the search index each use. Clear the cache instantly, or regenerate deleted previews from the originals. Privacy that is actually yours No sign-up, no ads, no cloud upload. Capture, recognition, search, and privacy protection all finish on your device, and your documents are never sent to a server. Built for professionals and business owners scanning contracts and receipts, students digitizing notes into PDFs, anyone storing sensitive paperwork safely, and anyone who wants a clean scanner with no ads, no account, working fully offline.
