Generators
Generators that run locally in your browser: QR and barcodes, passwords, UUIDs, PGP keys, favicons and Lorem Ipsum. No upload, no sign-up.
Last updated:
Every tool that creates something new in one place: QR codes and barcodes (DataMatrix, PDF417, Aztec), strong passwords, UUIDs, PGP key pairs, favicons and Lorem Ipsum placeholder text. Instead of searching across several categories, you find the right generator directly here.
Each generator runs entirely in your browser. That matters most for passwords and keys: they are created locally from your device's randomness and never sent to a server, so nothing is logged.
