## What this tool does
Pixel-diff two versions of a document page by page — differences highlighted in red so you can see exactly what changed before signing.

## Typical user problems
- The counterparty sent a "final" contract that looks identical to the draft — word changes hide in dense clauses and a changed digit in a price table is invisible by eye. Render both versions and diff them pixel by pixel; every edit shows red.

## Parameters


## Pricing
- Watermarked preview: free, no login required
- Final clean output: $2.99 one-time per task
- Require login (email/phone OTP) to complete payment
- Result available for download 24 hours after payment

## Limitations
- Visual comparison only — no semantic/text diff
- Rendering-based: identical content printed from different engines may show faint antialiasing noise
- Max 200 MB each
