How to scan a document to PDF on Android

Use Google Drive or your phone's scanner to make PDFs from paper documents, then polish them in Flint.

Android's camera plus Google Drive is one of the best document scanners going. Auto edge detection, deskew, multi-page support, OCR. Nobody talks about it because Apple owns the marketing for scanning.

The scan is easy. The post-processing is what people get stuck on.

Scanning with Google Drive

Open Drive. Tap + (new), then Scan. Point the camera at the page — Drive detects edges and snaps. Add more pages with the +. Tap Save. Drive uploads a multi-page PDF straight to your account.

Works on every Android phone with Drive installed (most of them).

Why scans need follow-up

Drive scans come out clean but big — typically 3–6 MB per page. A ten-page contract is 50 MB before you've even sent it. Gmail caps attachments at 25 MB. Compress drops most scans to a quarter of their size with no visible quality loss.

Sign and edit in the same trip

If the scan needs signing — leases, NDAs, school forms — pull it into Flint's signer and add your signature. S Pen makes it look real. Need to edit a field on the scan first? Edit the PDF — text edits work on born-digital PDFs; for scanned text, layer new text on top.

Samsung's scanner alternative

Galaxy phones have a scanner built into the Camera app — point at a document and a 'Scan' icon appears in the corner. Saves to the Files app as PDF. Same quality and same post-processing needs as Drive's scanner. Use whichever is closer to hand.

FAQ

Are Drive scans OCR-searchable?

Drive runs OCR on scans uploaded to your account — you can search the document text within Drive. The exported PDF includes a text layer in many cases, making it searchable in other apps too. Verify by opening in a PDF reader and trying to select text.

How big are Android scans?

Typically 3–6 MB per page, depending on phone and scanner. A 20-page document easily hits 80 MB raw. Compress before sharing — Flint usually gets it under 10 MB.

Can I scan multiple pages?

Yes. Both Drive and Samsung scanners support multi-page — keep tapping the + or 'Add' to feed in pages. Reorder before saving if the scanner shuffled them.

Scanned, but too big for email? Compress in Chrome and ship it.
