About ToolsFort

ToolsFort is your browser’s built-in toolbox: a collection of free, fast online tools — calculators, unit converters, text utilities and developer tools — built around three principles.

1. Instant

Every tool calculates as you type. There is no "submit" button and no waiting for a server.

2. Private

Every calculation runs in your browser with JavaScript. The numbers, text, files and passwords you enter are never uploaded to our servers.

3. Accurate and transparent

Each tool shows the formula it uses, worked examples and answers to common questions, so you can check the result and understand it.

No accounts, no email

ToolsFort has no sign-up, no logins and no newsletter. We never ask for your email address — you open a tool and use it.
