What Is a Text Case Converter?
A text case converter is a simple tool that transforms the capitalization of text. Whether you need to fix a wall of SHOUTING ALL-CAPS, standardize headings to Title Case, or create a fun alternating meme style, a case converter does the job in one click.
When Should You Use Each Case?
Sentence case is the standard for body text in most English writing — only the first word of each sentence and proper nouns are capitalized.
Title Case is the standard for headlines in journalism and publishing. Major words are capitalized; articles and short prepositions are not.
UPPER CASE is used for acronyms, emphasis, legal documents, and technical constants in programming.
lower case is common in URLs, email addresses, hashtags, and many programming identifiers (like Python variables).
Capitalized Case (every word capitalized) is sometimes used in marketing copy or product names.
Alternating case and Inverse case are primarily used for creative or humorous purposes.
