Text & Developer Tools
Fourteen browser-side utilities for text, encoding and web development — everything runs locally, so nothing you paste ever leaves your machine.
Encoding is not encryption
The Base64 Converter, URL Encoder and HTML Entities all transform text so it can travel safely through a channel that would otherwise mangle it — a URL, an email header, an HTML attribute. All three are trivially reversible by design and provide no security whatsoever. The Hash Generator is the opposite: a one-way fingerprint used to verify that data has not changed, not to hide it.
Working with structured data
The JSON Formatter indents, validates and reports the first syntax error with its position, which is usually all you need to find a stray comma. The UUID Generator produces version 4 identifiers — 122 random bits, which is enough that collisions are not a practical concern even across billions of records. The Timestamp Converter moves between Unix epoch seconds and readable dates in either direction.
Text and content utilities
The Word Counter gives words, characters with and without spaces, sentences and reading time — the figures that word limits and content briefs are actually measured in. The Case Converter switches between camelCase, snake_case, kebab-case, Title Case and the rest. The Lorem Ipsum produces placeholder text by paragraph, sentence or word count.
Design and security helpers
The Color Converter moves between HEX, RGB and HSL — HSL being the one worth learning, because adjusting lightness while holding hue and saturation is how you build a coherent palette. The Password Generator creates strong random passwords in your browser, and the QR Generator encodes a URL or text into a scannable code, again entirely locally.
