About Toolcedar

Toolcedar is a collection of small, single-purpose online tools — formatters, converters, generators and calculators. Each one does a single job, needs no account, and is free to use with no usage limits.

There is no catalogue of features to learn. If a tool needs an explanation to be usable, that is a fault in the tool rather than in the reader.

This is the part worth knowing. The tools are not a front end for a server that does the work — the work happens on your own machine, in JavaScript, after the page has loaded. Nothing you paste is transmitted, logged or stored anywhere, because there is nowhere for it to go.

That is why it is safe to paste a production payload into the JSON formatter or a token into the JWT decoder. You do not have to take that on faith either: open your browser’s network panel and watch while you type. There is no request to see.

Most tools here have a companion article. They are not padding. A tool tells you what the answer is, and the article explains why it is that answer — which characters actually need escaping, why a longer loan costs disproportionately more, what a decoder genuinely cannot do for you.

Where a subject has a common misconception, the article says so plainly rather than repeating it.

There is no contact form, because a form needs a server and this site deliberately does not have one. Email works and reaches a person.

• Anything general — corrections, a bug in a tool, a suggestion for one that should exist: hola@toolcedar.com
• Privacy and data requests: contacto@toolcedar.com

Corrections are genuinely welcome. If something here is wrong, it is wrong on a page that people find through search, which makes it worth fixing quickly.

No accounts, no tracking cookies, and nothing you type in a tool leaves your device. The full detail is in the privacy policy.
