Scan paper into a searchable PDF — on your device.
Capture a document with the camera, let edge detection square it up, and turn it into a PDF whose text you can search — recognised entirely on your phone, never uploaded.
One purchase. No subscription, ever.
From paper to searchable PDF
Capture, clean up, and recognise — without a round trip to a server.
Capture & straighten
Point the camera at a page; edge detection finds the document and squares the corners.
Searchable OCR
Text is recognised on-device, so you can search inside the scan later.
Multi-page PDFs
Add page after page into one clean PDF, then share or file it.
Private because of how it's built
PDF Bench has no network access at all. There is nowhere for your documents to go.
Stays on your device
Every file, edit and signature is stored only on your phone. No cloud, no account, no sign-up.
Works fully offline
The app never touches the internet — it behaves the same in airplane mode.
No ads, no tracking
No analytics, no trackers, no data collection. You paid for the app — you are not the product.
Questions
Does the scanner need the internet or an account?
No. Capture and text recognition both run on your device, with no account and no network.
Are my scans uploaded for OCR?
Never. The OCR model runs on your phone; the pages and recognised text stay on the device.
Can I search the text in a scan?
Yes. Because the text is recognised on-device, scans become searchable like any other PDF.
