About the Text Case & Format Converter
The Text Case & Format Converter is a free, browser-based utility that reformats your text in a single click. Beyond switching between UPPERCASE and lowercase, it offers Title Case, Sentence case, alternating and inverse case, plus developer-friendly formats such as camelCase, PascalCase, snake_case, CONSTANT_CASE and clean kebab-case URL slugs. It can also tidy messy text — collapse extra spaces, trim lines, strip blank lines and remove line breaks — and even build ready-to-paste HTML by wrapping each line in <li>, a full <ul> list or <p> tags.
Writers, marketers, developers and students rely on these conversions every day. Consistent casing keeps headings and tags tidy, slugs power SEO-friendly URLs and file names, and the reorder tools (reverse text, reverse words, sort lines A→Z and remove duplicate lines) make quick work of cleaning data. Everything runs locally in your browser, so it is instant, private and unlimited — with live character, word, line and sentence counts, an undo button and one-click copy or download.
