How to use Document Scanner

  1. Upload a photo of your document, take a picture with your camera, or paste from clipboard.
  2. Click "Auto Detect Edges" to let the tool find the document corners automatically.
  3. Fine-tune the corner positions by dragging the colored handles on the preview.
  4. Adjust brightness, contrast, sharpen, or apply black-and-white threshold as needed.
  5. Export your straightened document as PNG or PDF.

What is Document Scanner?

This document scanner lets you capture or upload a photo of a document and turn it into a clean, straightened scan. It uses edge detection (Sobel contrast analysis) to automatically find the document corners, then applies a perspective warp to flatten and straighten the document.

Fine-tune the results with draggable corner handles for manual adjustment, brightness and contrast sliders, a sharpen filter, and an optional black-and-white threshold for crisp text documents. Export your finished scan as a high-quality PNG image or a PDF file.

All processing is done client-side using Canvas 2D — your document images never leave your device.

FAQ

Does this work with curved or folded documents?
The perspective correction works best on flat documents photographed at an angle. Severely curved or folded documents may require additional flattening that this tool does not provide.
What image formats can I use?
You can upload PNG, JPEG, WebP, and other common image formats. You can also take a photo directly using your device camera or paste an image from your clipboard.
Are my document images secure?
Yes. All processing — edge detection, perspective correction, and adjustments — is done entirely in your browser using Canvas 2D. Your document images are never uploaded to any server.
What export formats are available?
You can export as a PNG image (lossless) or as a PDF file. You can also copy the scanned image directly to your clipboard.
