Generators
04 toolsTrueScalers publishes three generators: a password generator, a random number generator and a version 4 UUID generator. All three draw from the Web Crypto cryptographically secure pseudorandom number generator inside the browser, so generated values are never transmitted to a server, logged, or recoverable after the page is closed.
Passwords, random numbers and UUIDs, drawn from the browser’s cryptographic random number generator. Nothing leaves the page.
QR code generator
Create QR codes for URLs, Wi-Fi, contact cards, email and SMS. Download as PNG or SVG. No account, no expiry, no redirect.
