Document Scan

Online document scan & deskew tool: upload a phone photo of paper, a card or a receipt, drag the four corners, and the tool perspective-corrects it into a flat front-on view. Pick color / grayscale / B&W (scan) enhancement for a crisp scanned look. Everything runs locally — files are never uploaded.

How to use

Purpose

Document scanner / perspective correction — take a phone photo of a document, the tool auto-detects edges and applies perspective transform to produce a flat, scanner-like image. Optional B&W mode removes shadows / paper tint, edge sharpening enhances text. Export as PDF (multi-page supported). Documents (contracts, IDs, notes, receipts) contain sensitive data and are strictly processed locally — a meaningful privacy improvement over CamScanner / similar cloud-based scanners.

Steps

  1. Take or upload a phone photo of a document
  2. Auto-detect the four corners of the document
  3. Manually adjust corners if auto-detection misfires
  4. Apply perspective correction → flattened result
  5. Pick mode: color / B&W (best for uneven lighting) / enhance (sharpens text)
  6. Export JPG / PDF (multiple pages merge into one PDF)

FAQ

How does it compare to a real scanner?
Under even lighting with perspective correction + enhancement, results approach 300 DPI scanner output. Uneven lighting causes shadows — the B&W mode largely eliminates them by removing color and tonal variation.
Can I scan multi-page documents into one PDF?
Yes — upload several photos, process each page, then click 'Export PDF' to merge into one document. Ideal for contracts, multi-page reports, notes.
Is my document uploaded?
Never. Contracts, IDs, notes — strictly local processing. This is our biggest differentiator vs CamScanner, ScannerPro, and similar cloud apps.
What if auto-detection fails?
Switch to manual mode — drag the 4 corners to the document's exact corners, perspective correction applies your specified mapping.
When to use B&W mode?
Uneven lighting (one side bright, the other dark), yellowed paper, mild shadows — B&W mode discards color and keeps only text strokes, producing crisp output.

Use cases

  • Contracts / agreements digitization
  • Notes / whiteboard archive
  • Receipts / invoices for expense filing
  • Passport / ID document backup
  • Books / articles scan as OCR input

Use cases

Phone shot → perspective correction + B&W mode + multi-page PDF. Local-only — better privacy than CamScanner. Contracts, IDs, notes all benefit.
