About this tool
Retyping text just to fix its capitalization wastes time — this tool converts a whole block of text to the case style you need in a single click, without touching the words themselves. It handles the common cases writers need daily, plus a few developer-oriented formats.
Title Case here follows the common editorial convention of capitalizing major words while leaving short connecting words like 'a', 'the', and 'of' lowercase (except at the start), which produces more natural-looking headlines than a naive 'capitalize every word' approach.
Why use it
- Seven case styles in one tool
- Editorial-style Title Case, not naive word capitalization
- One-click conversion, no retyping
- Works on any length of text
- Nothing you type leaves your browser
Frequently asked questions
What's the difference between Title Case and Sentence case?
Title Case capitalizes most words (skipping short connectors like 'and' or 'of'), the style used in headlines. Sentence case capitalizes only the first letter of each sentence, like normal prose.
What are camelCase and snake_case used for?
They're common naming conventions in programming — camelCase joins words with no spaces and capitalizes each new word (myVariableName), while snake_case joins them with underscores in lowercase (my_variable_name).
Will converting case change my punctuation or spacing?
No, only letter casing is changed — punctuation, numbers and spacing (except in camelCase/snake_case, which remove spaces by design) are left untouched.
Can I undo a conversion?
Simply paste your original text back in, or use your browser's undo (Ctrl+Z / Cmd+Z) while focused in the text box.
Is my text stored anywhere?
No, all conversion happens instantly in your browser and nothing is saved or transmitted.
