ScanFree is a fast, clean PDF document scanner built for people who just want to scan documents to PDF or JPG and get back to work.

Most scanner apps let you scan a few pages and then trap your file behind a watermark, a mandatory cloud login, or a surprise subscription wall. ScanFree is different: a document scanner without watermark and without an account — built to finish, save, and share.

✓ No watermark stamped on your PDF or JPG scans
✓ No account, no sign-up, no cloud lock-in
✓ 100% offline document scanner — your files never leave your phone
✓ Choose your PDF size when you share — High, Medium, or Low

SMART CAMERA, LIVE PREVIEW & DUAL-SCANNER FLEXIBILITY
• Live Page-Edge Preview: See the highlighted document boundary in real time on the camera screen before you tap the shutter, even on angled shots.
• Automatic Edge Detection & Perspective Fix: An on-device neural network finds all four corners of your page and straightens angled shots into flat, rectangular A4 or letter scans.
• Option to Scan with Google's Document Scanner: If our detector misses a tricky page (such as a low-contrast white sheet on a light surface), long-press Scan and pick "Google scan", or tap "Google scan" at the top of the camera. It opens once while ScanFree's own camera stays your default, and pages return into Crop, filters, and library just like a normal scan. (Needs Google Play services and internet once to download the model; works offline after that.)
• Precision Manual Corner Crop: Drag any corner handle to fine-tune your selection with pixel accuracy.
• Low-Light Flash Assistant: Detects dark rooms and lets you turn on the camera torch with a single tap.

4 OFFICE-GRADE SCAN FILTERS
• Original: Keep the natural photo exactly as captured after perspective straightening.
• Enhance: Brightens paper to clean white while sharpening dark ink for crystal-clear reading.
• Color: Keeps the page in full color while whitening the background — preserves blue pen signatures, official stamps, letterheads, and book covers.
• B&W: High-contrast black and white filter ideal for office printing, photocopying, and compact file sizes.

MULTI-PAGE PDF & NON-DESTRUCTIVE EDITING
• Multi-Page PDF Creator: Capture up to 50 pages into a single document, or add new pages to an existing scan at any time.
• Smooth Drag-and-Drop Reorder: Long-press and drag pages in the 2-column or 3-column grid to rearrange page order, then rebuild your PDF automatically.
• Batch Filter: Apply Original, Enhance, Color, or B&W across all selected pages at once.
• Non-Destructive Re-Crop: Your full original photo is kept alongside the cropped page, so you can re-open any page later to adjust corners or switch filters without losing quality.
• Gallery Import: Convert existing photos and images from your phone gallery into clean PDF documents or JPG files.
• Share-Ready PDF Sizes: When you share a PDF, pick High (full quality, as captured), Medium, or Low (compact, made for email and WhatsApp).

WHAT YOU CAN SCAN WITH SCANFREE
• Office Papers: Official notices, letters, contracts, memos, invoices, and signed agreements.
• Receipts & Bills: Paper receipts, expense slips, and utility bills for tax and accounting.
• ID Cards, Passports & Certificates: Private offline copies of national IDs, certificates, and forms that never touch a server.
• Study Notes & Books: Handwritten notes, class handouts, and printed worksheets into neat multi-page PDFs.

PRIVATE BY DESIGN & COMMUNITY SUPPORTED
ScanFree contains no analytics trackers and no cloud servers. Every scan is processed and stored exclusively on your device, and exports go straight to your phone's Downloads folder.

ScanFree is supported by optional tips from users who love it. After you download or share a file, you will see a compact confirmation with an optional "Support ScanFree" button — your file always exports first, whether or not you ever tip. Support unlocks nothing; every feature is included.
