ProAbout these tools
The QR codes and passwords are worth a particular note. The codes encode your data directly rather than pointing at a redirect service, so a printed code cannot be switched off by somebody else going out of business; the passwords come from the browser's cryptographic random source and are never transmitted.
Frequently asked questions
Do the QR codes expire?
No. The data is inside the image itself, so there is no account or redirect service that could lapse and break a printed code.
Is a generated password ever sent anywhere?
No. It is produced by your browser's Web Crypto API and stays on your device.

11 tools SEO ToolsThe technical side of getting a page indexed and shared properly: the tags that decide how it appears in results, the structured data behind rich results, and the files crawlers read before anything else.
8 tools Developer ToolsThe small utilities that come up mid-debug — reading a token, testing a pattern, generating identifiers, tidying a query — without pasting anything sensitive into a stranger's server.
9 tools Social Media ToolsTools for the part of posting that is fiddly rather than creative — hitting each platform's dimensions, staying inside its character limits, and getting a thumbnail or a still that actually works.
9 tools CalculatorsEveryday arithmetic that is easy to get slightly wrong: percentage change and reverse percentages, an exact age, a loan repayment, a unit conversion, a meeting time across three countries.
