About LocalFirstTools

LocalFirstTools is a focused collection of 23 micro tools for people who work with JSON, tokens, encodings and identifiers. Every tool is a static page plus a script that runs in your browser — format, convert and inspect data without uploading a byte.

There is no account, no processing API, and no file store. If your network drops after the page loads, the tools still work. That is the product: inspect data without handing it to a website.

What we are

A privacy-first data toolkit for developers, no-code builders and anyone pasting payloads.

What we are not

A cloud converter, a PDF suite, or a place to upload confidential documents.
