Why Scan Documents With Your Phone?
Gone are the days of bulky flatbed scanners. Modern smartphones have cameras that are more than capable of producing crisp, legible document scans. Whether you're a student digitizing homework, a freelancer tracking receipts, or a traveler keeping passport copies handy, phone-based scanning is faster, more portable, and always with you.
The key is using the right app. A dedicated document scanner app does what your phone's default camera cannot: it automatically detects document edges, corrects perspective distortion, enhances text readability, and exports directly to PDF format — all in a few taps.
What You Need
- An Android phone with a working camera (Android 7.0 or newer recommended)
- PDF Scanner — a free, lightweight, offline scanner app
- The document you want to scan
- Decent lighting (natural daylight works best)
Step-by-Step: Scanning a Document to PDF
Install PDF Scanner from Google Play
Open the Google Play Store listing and tap Install. The app is free, takes minimal storage space, and requires no sign-up or account creation. You can start scanning immediately after installation.
Open the App and Position Your Document
Launch PDF Scanner and tap the camera button. Place your document on a flat, contrasting surface — for example, a white paper on a dark desk or vice versa. Hold your phone parallel above the document at a comfortable distance. The app's automatic edge detection will identify the document boundaries in real time.
Capture the Scan
Tap the shutter button to capture. The app instantly auto-crops the image to the detected edges and corrects any perspective skew — so even if you held the phone at a slight angle, the output looks straight and professional. You can fine-tune the crop handles manually if needed.
Enhance With Magic Color Filters
Choose from the app's Magic Color Filters to make your scan look its best. Black & White is ideal for printed text documents, Grayscale for handwritten notes, and Photo mode preserves full-color details for IDs, business cards, or receipts with colored logos.
Add More Pages (Optional)
Need to scan a multi-page document? Tap the add page button and repeat the capture process. All pages are combined into a single, organized multi-page PDF — perfect for contracts, homework assignments, or multi-page forms.
Save and Share Your PDF
Tap Save to export. Choose between PDF or JPG format. Your file is saved locally to your device — no cloud upload, no internet needed. From there, share directly via email, WhatsApp, social media, or any other app on your phone.
Bonus Features That Make Scanning Easier
OCR — Extract Text From Scanned Images
PDF Scanner includes a built-in OCR (Optical Character Recognition) text scanner. After scanning, you can extract the text from your document, copy it to your clipboard, and paste or share it anywhere — no need to retype a single word. This is incredibly useful for digitizing business cards, copying text from printed handouts, or grabbing information from receipts and contracts.
Gallery Import — Convert Existing Photos to PDF
Already have photos of documents in your gallery? You don't need to re-scan them. Use the Image to PDF Converter feature to import images directly from your photo library. The app supports JPG, PNG, and HEIC formats. Select multiple images and combine them into a single organized PDF.
