Mobile scanner that turns paper into clean, editable PDFs
Beginner
What is iScanner?
iScanner is a free iOS and Android scanning app that converts paper into clean PDFs with AI cropping, distortion correction, OCR in 23 languages, e-signature and a built-in editor. Extra modes cover math solving, object counting and room area measurement.
iScanner is a mobile document scanner built around a camera-first workflow. A phone or tablet becomes the capture device, and the app handles the rest: automatic cropping, distortion correction, and a rectangular, crisp result that looks like it came off a flatbed. The company describes itself as a US-based scanning and document management platform with more than 125 million users, and it is free to download on iOS and Android. Beyond basic capture, iScanner bundles a set of modes that go past what a scanner does. Math mode reads and solves equations from a photo, Count mode tallies similar objects in a frame, and Area mode builds a 3D room plan and calculates surface area, which makes it useful for remodeling and real estate work. An AI straightener fixes skews, warps and curves across a page, and smart filters retouch scans by cleaning up background noise. OCR converts scans into editable text in 23 languages, and a live text extractor grabs text as it appears in the camera. On top of that sits a document editor: e-signature and stamps, merge and split, page reordering, page numbers, annotations, text editing and hiding, images, shapes and watermarks. Files sync to cloud storage so the same document opens on phone, tablet or desktop, and the web app lets users manage iScanner documents from a browser. The tool fits individuals and small teams that handle paperwork away from a desk: freelancers sending invoices, realty agents signing forms on site, students digitizing notes, and small businesses keeping records in order. It is a direct competitor to phone scanner apps rather than desktop PDF suites, so it wins on portability and speed (the site claims under 5 seconds to scan and save) and asks users to accept a mobile editing surface. Ratings are strong, with 4.7 on the App Store, 4.5 on Google Play, and 4.9 on several software review sites.
How do you use iScanner?
1Install the app
Download iScanner from the App Store or Google Play. There is no desktop installer; the phone app is the entry point, and the web app is used later for file management.
2Scan your first document
Open the camera capture and point it at a page. The app detects edges, crops automatically and saves a corrected scan, typically in a few seconds.3Clean up and retouch
Apply the AI straightener to remove skews and curves, then use smart filters to strip background noise and fingers from the image.
4Extract text and edit the file
Run OCR to turn the scan into editable text in one of 23 languages, then reorder pages, merge or split files, add page numbers and annotations in the editor.
5Sign and send
Add an e-signature or stamp to finish contracts and forms, then export the PDF and share it by email or another channel.
6Sync across devices
Turn on cloud storage so scans open on tablet and desktop, and manage the document library from the website if the phone is not at hand.
