About This Tool

Phone cameras are convenient, but raw photos of documents are rarely flat, square, or easy to read. This page corrects that by letting you manually align the document edges and apply scan-style filters.

It is a practical replacement for a quick scanning app when you need better readability, cleaner geometry, or a more formal-looking image before sharing, archiving, or further OCR processing.

Why People Use It

  • Manual corner alignment for better perspective correction
  • Readable scan filters including B&W, grayscale, color, magic, and light
  • Runs fully in the browser for document privacy

Typical Use Cases

  • Straightening mobile photos of forms and contracts
  • Cleaning up receipts for claims and accounting
  • Improving readability before OCR and archiving
  • Creating flatter scans without a dedicated scanner app

How To Use Document Scanner

  1. Step 1

    Upload a photo of the document you want to clean up.

  2. Step 2

    Drag the four corner handles to match the visible document edges.

  3. Step 3

    Choose the filter that best suits the page content.

  4. Step 4

    Download the corrected scan as a JPEG image.

Common Questions

Does the scanner auto-detect the page edges?

The current workflow is manual, which gives you direct control over the four corners and often produces more predictable results on difficult images.

Which output format do I get?

The document scanner exports a flattened JPEG that is easy to share and reuse in other workflows.

Are document photos uploaded anywhere?

No. The document scanner runs in the browser, so the source image remains on your device during processing.
