Why it matters

When You Need a Scanned Look

Legal

Contracts and official docs

Many platforms and institutions require documents to look scanned — signatures, stamps, and official seals need that scan aesthetic to appear legitimate and processed.

Clean

Clean up whiteboard photos

A photo of a whiteboard is hard to read — glare, uneven lighting, color cast. B&W scanner mode strips all of that away and leaves only the content.

Pro

Professional receipts and invoices

Scanned-looking receipts are easier to read, archive, and expense. Turn a crumpled phone photo into a clean grayscale document that accounting will actually accept.

Style guide

Three Scan Styles — Know When to Use Each

Each style applies a different pixel-level transformation. The right choice depends on your document type.

Grayscale

Most natural

Removes color while preserving all shading and contrast. Produces the most natural scanned appearance. Best for documents with photos, complex shading, or when readability with visual depth matters.

Best for

  • Receipts with logos
  • Mixed text+photo documents
  • Professional reports

Black & White

Cleanest text

Applies an adaptive threshold — every pixel becomes pure black or pure white. Produces the cleanest text legibility and smallest file sizes. Best for text-only documents and handwritten notes.

Best for

  • Contracts
  • Handwritten notes
  • Whiteboards with text
  • Receipts

Color Enhance

Vibrant & sharp

Boosts contrast and saturation without removing color. Ideal for colored diagrams, highlighted notes, or any document where color carries meaning.

Best for

  • Colored diagrams
  • Highlighted text
  • Colored forms
  • Mind maps

Tips for the best scan result

Flat surface: Place your document on a flat, non-reflective surface before photographing.

Even lighting: Avoid shadows across the document — soft overhead light gives the most consistent result.

Straight angle: Shoot directly above, not at an angle. Perspective distortion makes edges appear skewed.
