What types of documents can you scan with the Docutain Scanner app?

Updated

Docutain is a mobile scanning and document management app for Android and iOS that handles essentially any paper document you can photograph — forms, receipts, invoices, and general paperwork — and turns it into a PDF or image with OCR text recognition. It suits anyone who wants to digitize, organize, and share documents from a phone, whether for private archiving or business use. The app is described as free to download and try, and the site says it is used by several million users.

Document types you can scan

The site names these categories directly:

  • Forms — paperwork you need to fill in or file digitally
  • Receipts — expense and purchase records
  • Invoices — including the kind of PDF invoices used in billing workflows
  • General documents — the site frames the app around "all kinds of documents" and "all your paperwork," so anything on paper that fits in front of the camera is in scope

Because the app applies OCR, scanned invoices and receipts become searchable text rather than flat images, which is what makes them useful for later retrieval.

How scanning quality is handled

You don't frame the shot manually. According to the site, the app:

  1. Automatically detects the edges of the document and scans it instantly
  2. Applies perspective correction so a photo taken at an angle comes out rectangular
  3. Crops to the document boundaries
  4. Offers color filters to improve the result

The practical effect: you point the camera roughly at the page, and the app does the straightening and trimming. This matters most for receipts and forms, where a skewed or over-cropped scan can make text unreadable.

What you can do after scanning

  • Add more pages to an existing scan
  • Rearrange the scanned pages
  • Edit pages as needed
  • Create a PDF from the scan with a single tap (the site describes both "Scan to PDF" and "Image to PDF")
  • Search the text inside the app thanks to OCR
  • Share the result as a PDF or image via email, a local folder, or messenger apps such as WhatsApp

Organizing and storing scans

Docutain also works as a document manager. You can attach a title, document type, address, and tags to each document to group and structure them, and use a search bar to find them again. Documents can stay locally on your device or go to a cloud provider of your choice — the site says optional connections to common cloud providers are offered, and that you decide where documents are stored.

What to check before committing

The site's evidence covers scanning, OCR, PDF/image output, sharing, and organization, but does not state current pricing, subscription terms, or account requirements beyond "free to download and try." If cost or storage location is decisive for you, confirm those in the app store listing or in-app before relying on it for a large archive. For a quick test, scan one receipt and one multi-page form, then check whether the OCR text is searchable and whether the PDF opens correctly in your usual reader.
