How to Generate Custom QR Codes for URLs, WiFi, and Business Cards for Free

Quick Response (QR) codes have become ubiquitous across restaurants, product packaging, print advertisements, conference badges, and event ticketing. With a simple point of a smartphone camera, users can open websites, connect to WiFi networks, or save contact cards.

However, many online QR code generators use deceptive tracking redirects, place expiration dates on free codes, or require paid accounts to download high-resolution vector images.

Static vs. Dynamic QR Codes

Dynamic QR Codes: Route users through an intermediary tracking URL managed by the service provider. If the provider shuts down or cancels your subscription, the QR code immediately stops working.
Static QR Codes: The destination payload (URL, plain text, WiFi credentials, or vCard) is directly encoded into the binary matrix pattern of the QR code itself. Static QR codes never expire and function forever without any third-party dependency.

Error Correction Levels Explained

QR codes utilize Reed-Solomon error correction algorithms, allowing scanners to read codes even if they are partially smudged, torn, or overlaid with a logo:

Low (L - 7%): Highest data capacity, simplest pattern.
Medium (M - 15%): Default balance between density and durability.
Quartile (Q - 25%): Good for printed posters exposed to weathering.
High (H - 30%): Essential when placing a logo in the center or printing on rough materials.

Types of Payloads You Can Encode

Website URLs: https://example.com/landing-page
WiFi Networks: Automatically prompts phones to join networks without typing long passwords: WIFI:S:MyNetwork;T:WPA;P:SecretPassword123;;
Contact Cards (vCard): Saves contact info directly into the phone’s address book.
Plain Text & Cryptographic Keys: Encodes Bitcoin/Ethereum addresses or plain text notes.
