Case Converter - Upper, Lower, Camel & Snake Case
Convert text instantly between uppercase, lowercase, title, sentence, camel, snake, kebab, and alternating case formats.
TEXT CASE CONVERTER
Easily convert text between different cases: uppercase, lowercase, title case, sentence case, and more.
Essential for developers, writers, and editors who need to format text quickly and correctly.
Paste plain text, choose the target format, inspect the transformed text in the same field, and copy it when ready. Uppercase, lowercase, title, and sentence modes suit prose, while camelCase, snake_case, and kebab-case are useful for identifiers, filenames, and slugs.
Conversion uses deterministic character and word-boundary rules rather than an editorial style guide. Title and sentence case do not recognize every proper noun or acronym, identifier modes can remove punctuation, and each conversion replaces the current field value. Keep the source elsewhere when you may need to compare or undo a transformation.
