Built with the same on-device tech trusted by

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.

01

Capture

Open the app and point your camera. Edges lock on automatically as you hold steady.

02

Enhance

Pick a filter, rotate if needed, and add more pages to the same document.

03

Export

Choose A4, Letter, or Legal, add a password if it's sensitive, and generate.

04

Share

Send it straight from the share sheet, or keep it in your on-device library.

Built for real documents

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.
