Whether you're a developer needing unique identifiers, a business professional scheduling international meetings, a student converting measurements, or anyone needing to create QR codes or secure passwords, our comprehensive suite of utility tools provides everything you need for efficient daily operations.
Our QR Code Generator & Scanner is a versatile tool that supports multiple QR code types including URL codes, contact vCards, WiFi network configurations, plain text, and more. The generator allows customization of colors, sizes, and error correction levels, while the built-in scanner can read QR codes directly from your device's camera or uploaded images.
The Barcode Generator supports industry-standard barcode formats including Code 128 (most common), UPC-A, UPC-E, EAN-8, EAN-13, and Code 39. This is invaluable for small businesses, inventory management, product labeling, and retail applications where professional barcode generation is needed.
Our Unit Converter handles conversions across multiple measurement categories with precision and accuracy. Supported conversion types include:
Convert between meters, feet, inches, miles, kilometers, and more with precise calculations.
Convert between grams, kilograms, ounces, pounds, and other weight measurements.
Convert between Celsius, Fahrenheit, and Kelvin with accurate temperature scaling.
The Time Zone Converter is essential for global collaboration, supporting all major time zones with automatic daylight saving time adjustments. You can convert single times or create comparison tables for multiple time zones, making it perfect for scheduling international meetings, webinars, or coordinating with remote teams.
Our UUID Generator creates universally unique identifiers following RFC 4122 standards. These 128-bit identifiers are essential for database records, distributed systems, and applications requiring guaranteed uniqueness. The tool supports multiple UUID versions including version 1 (time-based), version 4 (random), and version 5 (namespace-based).
The Random Number and Password Generator creates cryptographically secure values for various applications.
