Generators
Create QR codes and barcodes, strong passwords, random numbers and strings, and ready-to-paste CSS for gradients and shadows. Generators use your browser's cryptographically secure random number generator where randomness matters.

Security-sensitive generators (passwords, random strings, UUIDs) use crypto.getRandomValues, the same source browsers use for encryption keys, and never Math.random.
QR codes and barcodes are generated as crisp vector SVG or high-resolution PNG so they scan reliably when printed.
Frequently asked questions
Do generated QR codes expire?
No. The QR codes are static: the content is encoded directly in the image, with no redirect or tracking link, so they work forever.
Are generated passwords stored?
No. Passwords are generated in your browser and never transmitted or logged.
