How to scan documents to PDF on Android

Android doesn't come with a single obvious "scan" button, so many people photograph documents and send blurry, tilted JPGs. With the right tool you can produce a proper multi-page PDF in under a minute — and you have three good options.

Option 1: The Osd-Scan app (best results)

The Osd-Scan app is built for scanning. It runs entirely on your phone, so it's fast and private.

1. Install Osd-Scan from Google Play and open it.
2. Tap the camera button in the middle of the bottom bar.
3. Hold the phone over the page. A blue outline follows the edges of the paper.
4. Keep still — the page is captured automatically and a blue check confirms it.
5. Place the next page; the camera keeps scanning until you tap Done.
6. Review the pages, change a filter if you like, then tap Save PDF.

The PDF lands in Downloads › Osd-Scan. Tap Share to send it straight to WhatsApp, Gmail, Drive or any other app.

Option 2: Scan in the browser — no app needed

If you don't want to install anything, open Chrome and go to osd-scan.com/scan. Tap Scan with camera, allow camera access, and scan exactly as you would in the app. The PDF downloads to your phone. Everything is processed inside the browser, so the files are never uploaded.

Option 3: Google Drive or Files by Google

Some Android phones include a scan option in Google Drive or in the Files app. These are fine for a quick scan, but they offer fewer cleanup options and Drive uploads every scan to your account. If the document is sensitive — an ID, a bank statement, a medical report — a local scanner is the safer choice.

Get a sharp scan on any Android phone

• Clean the lens. Phones live in pockets; a fingerprint on the lens makes every scan look hazy.
• Use daylight. Stand near a window and avoid casting your own shadow on the page.
• Dark background. A wooden table or dark folder helps edge detection.
• Hold parallel. The app corrects angles, but a straighter photo means sharper text.

After scanning: what else you can do

Because Osd-Scan includes 24 PDF tools, you can finish the job on your phone:

• Merge several scans into one PDF
• Compress a large PDF to send it by email
• Sign a contract with your finger
• Make it searchable with OCR in 24 languages
• Protect it with a password before sharing

Open PDFs from other apps

Received a PDF in WhatsApp or Gmail? Tap Open with (or Share) and choose Osd-Scan. The app asks which tool you want — compress, sign, merge and more — and opens the file directly.

Scanning on Android is now as easy as taking a photo, and the result is a document you can confidently send to an employer, an accountant or a government office.
