Convert text to UPPERCASE, lowercase, Title Case, camelCase, snake_case, kebab-case and more instantly.

Real-time character, word, line, sentence count plus Twitter / SMS / meta-description limit warnings. Grapheme-aware (emoji counts as 1).

Strip duplicate lines from any list, preserving the first occurrence and original order. Case + whitespace toggles, optional alpha sort.

Find and replace across a block of text — plain or full regex with back-references, case toggle, multiline mode.

Whitespace cleanup with surgical control — collapse spaces, trim lines, collapse newlines, remove blank lines, or strip ALL whitespace.
