About Invoice Gen
What this tool does
Generator tools create passwords, UUIDs, Lorem Ipsum placeholder text, QR codes, barcodes, fake data sets, random numbers, and various code snippets. Each output is generated fresh on every click using cryptographic or pseudo-random algorithms.
Why use this tool
Developers and designers constantly need test data, unique identifiers, and placeholder content during prototyping. Generating them locally avoids dependency on external APIs and keeps sensitive outputs like passwords off the network.
How it works
For security-sensitive outputs (passwords, UUIDs), the tool uses the Web Crypto API's crypto.getRandomValues(). For placeholder text, it assembles words from a built-in dictionary. QR codes and barcodes are rendered to canvas or SVG.
Pro tip
For passwords, enable all character classes and use at least 16 characters. A passphrase of 4-5 random dictionary words is equally strong and much easier to remember.
