About these generators tools

Generators produce something new instead of transforming an input: secure passwords from the browser's crypto engine, QR codes and barcodes as downloadable images, and clearly-marked fake data for tests. Everything is computed locally — no external API is called and nothing you generate is stored.

Each tool is a small, focused utility with its own page, its own instructions and its own set of supported inputs. There is no account to create and no server-side processing step: the work happens on your device.
