About the Case Converter

Retyping a heading because caps lock was on is a waste of a minute. Paste the text, pick a case, and copy the result. The converter handles eight formats: UPPERCASE, lowercase, Title Case, Sentence case, aLtErNaTiNg case, camelCase, snake_case and kebab-case.

Title Case follows the common English style rule of leaving short articles, conjunctions and prepositions such as "a", "of" and "the" in lower case unless they open the sentence. The programmer formats — camel, snake and kebab — strip punctuation first, so a plain English phrase converts cleanly into a variable name, a database column or a URL slug.

Key features of the Case Converter

Eight cases in one tool

Everyday formats and programmer formats sit side by side, so you never need a second converter.

Title Case that follows the style rule

Short articles, conjunctions and prepositions such as "a", "of" and "the" stay lowercase unless they open the line.

Clean camel, snake and kebab output

Punctuation is stripped first, so an ordinary English phrase converts straight into a variable name, a column name or a URL slug.

Works on any length of text

A single heading or several pages convert the same way, with no character cap.

One-click copy

The converted text is copied to the clipboard in a single click, with the original left untouched.
