Free Online Generators — UUID, QR Code, Lorem Ipsum & More
Generators create unique data on demand — UUIDs for database records, QR codes for sharing links, placeholder text for designs, or random passwords for security. These tools give you exactly what you need in seconds.
All generation happens client-side. UUIDs use cryptographic randomness, QR codes render instantly, and passwords are never stored or transmitted.

Frequently Asked Questions
Are generated UUIDs truly unique?
UUID v4 uses 122 random bits, giving 5.3 x 10^36 possible values. The probability of a collision is astronomically low — far less than 1 in a billion even after generating billions of UUIDs.
Can I customize QR code colors and size?
Yes. Our QR code generator lets you set custom foreground and background colors, adjust size, and download the result as a PNG image.
What UUID version does the generator create?
The generator creates UUID v4 (random), which is the most commonly used version for application identifiers. It uses the Web Crypto API for secure random generation.
