About

What Is This Tool?

Text Case Converter is a free, instant tool for converting text between any capitalization format — UPPER CASE, lower case, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, SCREAMING_SNAKE_CASE, dot.case, and aLtErNaTiNg case. Paste your text, click a format, copy the result.

Who Built It?

This site was built by a small independent developer to solve a common everyday need for developers, writers, and students. Switching between naming conventions is tedious — this tool makes it instant.

Our Mission

Developer tools should be fast, free, and work without a login. Text Case Converter runs entirely in your browser with no server round-trips, no tracking of what you type, and no account required.

Supported Formats

The converter supports 11 case formats covering the most common programming conventions (JavaScript, Python, CSS, SQL), writing styles (Title Case, Sentence case), and a few fun ones. All conversions handle multi-word inputs, mixed input cases, and camelCase splitting automatically.

Privacy

Text you enter is never sent to any server. All processing happens locally in your browser — your text stays private. See our Privacy Policy for full details.
