What is Document Scanner?
Document Scanner is a free browser-based tool that transforms your phone camera or webcam into a document scanner. It automatically detects document edges, corrects perspective distortion from angled photos, and lets you enhance scans with brightness, contrast, and black & white filters. Export multiple pages as a single PDF or as individual images.
Perfect for scanning receipts, contracts, ID documents, notes, business cards, whiteboards, or any flat document without needing a dedicated scanner or app.

Common Questions
Does this work on iPhone and Android?
Yes. The scanner works on any device with a camera and a modern browser. On mobile, use Safari (iPhone) or Chrome (Android). Position your phone parallel to the document for best results.
How does edge detection work?
The tool uses computer vision algorithms to detect rectangular shapes (document edges) in the camera feed. A green outline shows detected edges. For best results, place documents on a contrasting background.
Can I scan multiple pages into one PDF?
Yes. Scan as many pages as needed—each appears as a thumbnail. Reorder pages by dragging them. When done, click "Download PDF" to get a single PDF containing all pages in order.
Why should I use black & white mode?
B&W mode is ideal for text documents. It improves readability, reduces file size significantly, and creates cleaner scans for OCR processing. Color mode is better for photos or documents with important color information.
What resolution are the scanned images?
Scan resolution depends on your camera quality. Most modern phones capture at 1080p or higher, producing high-quality scans suitable for printing or archiving. Desktop webcams may produce lower resolution.
