About Tools Hub

Tools Hub is a small collection of utilities for everyday tasks. Each tool is a single page that does one job and does it without getting in the way:

• Password Generator — Strong random passwords with a live strength estimate.
• Base64 Tool — Encode and decode text, including Cyrillic and emoji.
• JSON Formatter — Validate, format and minify JSON with exact error positions.
• Text Analyzer — Words, characters, sentences, reading time and top words.
• Color Converter — HEX, RGB and HSL, shades and WCAG contrast.
• Hash Generator — SHA-1, SHA-256, SHA-384 and SHA-512 for text or a file.
• UUID Generator — Random version 4 UUIDs, one or many.

How it works

The site is static. All calculations happen in your browser using standard web APIs, which means the tools keep working at the speed of your own device and your input never needs to leave it. There are no accounts, no tracking scripts and no advertising.

Browser support

Any current version of Chrome, Edge, Firefox or Safari. The hash and UUID tools rely on the Web Crypto API, which is only available on secure (HTTPS) pages.
