About Pixel-Perfect Margin Inspector

The Pixel-Perfect Margin Inspector is a precision QA tool built for designers, frontend developers, and design system teams who demand accuracy. Paste a screenshot, hover anywhere, and instantly measure spacing, padding, or gaps — all calculated using high-contrast pixel detection and smart directional rays.

Key Features

  • Smart Hover Engine: Detects visual boundaries using adaptive color-contrast logic.
  • Instant Pixel-Gap Detection: Mouse over any whitespace to reveal exact distances.
  • Two-Side & Single-Side Modes: Measure full gaps or only one direction as needed.
  • Zoom-Based Precision: Use Ctrl + Scroll for sub-pixel QA.
  • Client-Side Privacy: Screenshots never leave your browser — no uploads.
  • Perfect for QA: Ideal for Figma→Frontend verification, audits, and UI regressions.

Who Uses This Tool?

  • UI/UX designers validating spacing consistency
  • Frontend developers debugging CSS margin/padding mismatches
  • QA engineers conducting pixel-perfect visual regression tests
  • Design system maintainers checking strict layout rules
  • Agencies delivering precise client work

How It Works

  1. Paste a screenshot or upload any UI image.
  2. Move your cursor — the tool fires detection rays in all directions.
  3. The algorithm identifies nearest visual edges via pixel contrast shifts.
  4. Vertical & horizontal spacing instantly appear as labeled measurement lines.
  5. Adjust threshold sensitivity if your UI uses subtle color changes.
