Turn your camera into a document scanner
Point, capture, done. SnapPDF detects edges automatically, cleans up the shot, and builds a crisp multi-page PDF. No cloud upload, no waiting.
Everything a scanner app should do, and nothing it shouldn't
No accounts, no ads, no upload limits. Just a fast path from camera to a finished PDF.
Automatic edge detection
Point your camera at a page and SnapPDF finds the corners, corrects perspective, and crops it clean. No manual dragging required.
Five one-tap filters
Magic Color, Black & White, Grayscale, and Strong Contrast, tuned for readable scans, not Instagram.
Built-in OCR
Pull selectable, searchable text off any page in seconds.
Fully offline
Every scan and PDF is processed on your device. Nothing leaves your phone.
Multi-page documents
Keep scanning, then reorder, rotate, or delete any page before you export a single combined PDF.
From camera to PDF in four steps
The whole flow is designed to take under a minute per document.
Capture
Open the app and point your camera. Edges lock on automatically as you hold steady.
Enhance
Pick a filter, rotate if needed, and add more pages to the same document.
Export
Choose A4, Letter, or Legal, add a password if it's sensitive, and generate.
Share
Send it straight from the share sheet, or keep it in your on-device library.
Handle contracts, receipts, and IDs like they matter
AES-256 password protection
Lock any exported PDF with a password before you share it.
Reorder & rotate freely
Fix a sideways page or move it to the back without rescanning.
Standard page sizes
Export to A4, US Letter, or Legal, whatever the recipient expects.
I scan every receipt for expense reports now instead of stuffing them in a drawer. The auto-crop is scary accurate.
Password-protecting a lease before emailing it took two taps. That alone replaced three other apps for me.
Offline OCR on lecture notes is the whole reason I installed it. Searchable PDFs, zero uploads, done.
