Our document scanner uses advanced computer vision algorithms to automatically detect the edges of your document in a photo. It then applies perspective correction (homography transformation) to straighten the document, removes shadows, enhances contrast, and sharpens text for a professional scanned appearance. All processing happens in your browser using JavaScript and HTML5 Canvas.

You can scan any type of paper document including receipts, invoices, contracts, business cards, notes, letters, certificates, whiteboards, handwritten notes, forms, tickets, and more. The tool works best with rectangular documents that have clear edges.
We support all popular image formats including JPEG, PNG, WebP, HEIC, and more. You can upload photos taken with your smartphone, digital camera, or from any image file on your computer.

Choose Color mode for documents with important colors like receipts, colorful forms, or photos. Select B&W (black and white) for text-heavy documents like contracts or handwritten notes - this reduces file size and improves text clarity. Use High Contrast mode for faded, low-quality, or difficult-to-read documents that need maximum enhancement.

For best results: 1) Take photos in good lighting conditions. 2) Position the camera directly above the document when possible. 3) Ensure the entire document is visible in the photo with some background around the edges. 4) Keep the document as flat as possible. 5) Use a contrasting background (e.g., white paper on dark table).
