What it does

Whatever the paper: a receipt, a letter, a notebook, a petition. All of it becomes a PDF and text on your phone.

  • A typewritten letter from 1903

    Scan with the camera or import

    Documents, receipts, notes, letters.

  • A notebook with alphabet tabs, around 1920

    Multi-page PDFs in one go

    Scan page after page; it becomes one PDF.

  • A restaurant receipt on a wooden table

    Automatic edge detection

    Perspective is corrected; the table leaves the frame.

  • A typewritten court complaint from 1886

    On-device OCR

    Text from every page; languages written in the Latin alphabet.

  • A handwritten letter on hotel letterhead, 1920

    Search across every scan

    Type a name, an amount or a date; results come from the text.

  • Offline Scanner: the recognised text screen

    Share the PDF or the text

    Copy the text, send the PDF.

Common questions

Is Offline Scanner paid?

No, it is free and supported by ads. Ads do not appear on the scanning screen; they come after a PDF is saved and when you return to the app.

Are my documents uploaded anywhere?

No. Scanning, PDF creation and text recognition all happen on your phone; there is no account and no cloud upload. Only ads use the internet.

Does it work without internet?

Yes. The scanner module is downloaded once through Google Play services the first time you use it (about 200 KB). After that, scanning works fully offline.

Which languages does text recognition support?

Languages written in the Latin alphabet: English, Spanish, Portuguese, German, Turkish, Indonesian and the like.

What does the search look through?

The recognised text and the name of every scan. Type a name, an amount or a date; matching scans stay in the list.

Which phones does it run on?

Android 7.0 and up, on phones with Google Play services.

Your scans,
on your phone.

Open it on Google Play and scan your first document. Scanning, PDFs and text recognition stay on the device. Type a word into the box on the Scans screen: the four sample documents find it in their text.
