  Full URL & expanded redirects (follows short links using safe HEAD requests, when permitted)

• 💳

  UPI payment details (UPI ID, payee name, amount, currency, notes, transaction refs)

• 🏷️

  Tracking parameters like UTM source/medium/campaign and other query strings

• 📶

  Wi-Fi configuration (SSID, encryption hints, etc.)

• 👤

  vCard contact fields (name, email, phone)

• 🧭

  Geo coordinates (for geo: or Maps links) with one-click viewing on Google Maps

• 🛡️

  Security cues (HTTPS vs HTTP, suspicious keyword flags, redirect expansion notice)

Why trust this tool?

We designed the experience around user safety and transparency. Our analyzer does not automatically redirect your browser to the destination page. Instead, it decodes the QR content locally and displays the information in a clean, human-readable layout. For shortened links, we attempt server-side expansion using a safe HEAD request—so you see the final URL string—but we still don’t take you there unless you choose to click.

Built for clarity and speed

Unlike generic QR readers that simply open a link, the QR Code Explainer shows you the full breakdown—domain, path, parameters, and campaign tags—and groups them into clean tables. That means you can instantly answer:

• ✅

  Is this a real UPI request or a link disguised as one?

• 🌐

  Which website will it open?

• 🏷️

  What tracking tags are attached?

• 🛡️

  Does the link look safe (HTTPS + reputable domain)?

• ↪️

  Is there a hidden redirect behind a short URL?

How it works (plain English)

1. Upload or scan a QR code (camera mode available on supported devices).
2. The tool decodes the QR content locally (e.g., URL, text, UPI, Wi-Fi, vCard, SMS, geo).
3. For URLs, it optionally expands shortened links via HEAD (no auto-navigation).
4. It then parses and explains the content with clear labels and tables, highlighting the details that matter.

Limitations & best practices

• 🌐

  Some servers block HEAD requests or CORS, so expansion may not always be possible. You’ll still see the original URL string.

• 💡

  UPI implementations vary by app; we extract commonly used parameters where present (e.g., pa, pn, am, tn, tr, tid, mc, cu).

• 🧭

  Suspicious keyword flags are heuristic hints—not definitive security verdicts. Always use judgment.

• 🔍

  When handling payment QR codes, confirm payee name and UPI ID through a trusted channel before paying.
