Frequently Asked Questions

How to generate qr code for free?

Use the utilAZ QR Code Generator - paste any URL, text, or data, choose your size and error-correction level, then click Generate. The tool runs entirely in your browser with no sign-up or watermark. Download the result as PNG or SVG instantly.

How to make a qr code for a link?

Paste your full URL (e.g. https://example.com) into the utilAZ QR Code Generator input field. The tool automatically detects it as a link and encodes it. Scan the generated code with any phone camera to open the URL directly.

What is the best free qr code generator?

The best free QR code generators are client-side tools that require no account, add no watermark, and support multiple data types. utilAZ meets all these criteria and adds real-time preview, custom sizing, adjustable error correction, and SVG/PNG export.

How to track qr code scans?

To track scans, encode a URL that passes through an analytics service (e.g. a UTM-tagged link or a short-link with built-in analytics). The QR code itself is static, but the destination URL can capture scan counts, locations, and device data.

How to customize a QR code with a logo?

Set the error correction level to H (30% recovery) so the code remains scannable even with a logo covering part of it. Then overlay your logo in the center. utilAZ supports custom foreground/background colors and high error correction to allow logo placement.

QR Code Technical Guide

Understanding the technical aspects of QR code generation helps you create reliable, scannable codes for any use case. Here are the key parameters that affect your QR code quality.

Error Correction Levels:

Level L - Low (~7% recovery)
Best for: Clean digital displays, maximum data capacity
Level M - Medium (~15% recovery)
Best for: General purpose, balanced size and reliability
Level Q - Quartile (~25% recovery)
Best for: Printed materials that may get slightly damaged
Level H - High (~30% recovery)
Best for: Codes with logos overlaid, harsh environments

Supported Data Types:

URL / Website Link
Opens a webpage when scanned
Plain Text
Displays any text message
WiFi Network
Auto-connects to WiFi (SSID, password, encryption)
vCard Contact
Saves contact info (name, phone, email, org)
Email / SMS / Phone
Pre-fills email, text message, or dials a number

Tip: Higher error correction levels make QR codes more resilient but also larger. Use Level M for most applications, and Level H only when you need to overlay a logo or expect physical damage.
