Text Case Converter

You can convert text into uppercase, lowercase, title case, sentence case, alternating case, and inverse case. These formats cover most writing, editing, publishing, social media, and text cleanup needs.

Title case capitalizes most major words in a title or heading, such as "How to Write Better Headlines." Sentence case capitalizes the first word of a sentence and proper nouns, such as "How to write better headlines." Sentence case is common for body text; title case is common for headings, article titles, and book titles.

Paste the all-caps text and choose sentence case or lowercase. Sentence case is usually better for paragraphs because it restores a more natural reading style by capitalizing sentence starts. You should still review proper nouns, acronyms, names, and brand terms manually.

The converter provides a practical general-purpose title case. Style guides differ on prepositions, conjunctions, hyphenated words, and special terms, so review the output if you are submitting academic, legal, or professional publishing work that must follow a specific standard.

Yes. You can paste multi-paragraph text, lists, or article sections. The tool preserves line breaks while changing capitalization. For very large documents, converting section by section can make review easier.

Case conversion can change acronyms and names depending on the selected format. For example, lowercase will turn NASA into nasa. Always review specialized terms, brand names, product names, names of people, and acronyms after conversion.

Inverse case swaps uppercase letters to lowercase and lowercase letters to uppercase. It is useful for creative effects, test data, accessibility checks, and quickly spotting case-sensitive differences in strings.

No. The conversion is designed for local browser processing during normal use. Your pasted content is not saved to an account or database by the tool, and closing or refreshing the page clears the current text from the page session.
