Change text case

A case converter is a free online tool for changing letter case in text. It supports uppercase (UPPERCASE), lowercase, Title Case, Sentence case, camelCase, snake_case, kebab-case and other formats. Online text case conversion is useful for copywriters, programmers and editors when preparing headings, variable names and formatting content.

Title Case — each significant word starts with a capital letter (as in headings). Sentence case — only the first letter of the sentence is capital, the rest lowercase. Both modes are available in our free online case converter.

These are naming formats for programming: camelCase — concatenated, each word capitalized (except the first); snake_case — words with underscores; kebab-case — with hyphens. Online text case converter helps quickly convert text to the right format for code, URLs or file names.
