Why Use the Case Converter?

Whether you are cleaning up a headline, renaming variables, or fixing text typed with caps lock on, retyping is a waste of time. Paste your text, pick a case style — UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, or kebab-case — and copy the result.

Common use cases

  • You have a Text file and need it in Text format for notes, logs, and readme files.
  • The target software or platform requires Text but your file is in Text.
  • You want to reduce file size or improve compatibility without using desktop software.
Keep in mind: No formatting, structure, or metadata — plain text carries only the characters themselves.
