A Case Converter changes the capitalisation style of a text without requiring you to retype it. It can transform content into UPPERCASE, lowercase, Title Case, Sentence case and other supported formats with a single selection. Consistent capitalisation improves the readability and presentation of headings, titles, product names, data fields, code labels and other written content. Manually correcting a long text can be time-consuming and may introduce inconsistencies. A case conversion tool applies the selected style across the complete input instantly. ## How to Convert Text Case Paste or type the text you want to edit into the input area. Select the preferred case style, then copy the converted result for use in your document, content management system, spreadsheet, code editor or publishing platform. The available options include: * **UPPERCASE:** Converts every letter to a capital letter. * **lowercase:** Converts every letter to a lowercase character. * **Title Case:** Capitalises the main words in titles and headings. * **Sentence case:** Capitalises the beginning of sentences while keeping the remaining text primarily lowercase. The most appropriate option depends on where the content will appear. Uppercase can be useful for short labels or identifiers, while sentence case is generally easier to read in longer copy. Title case can create consistent headings, but editorial rules may differ regarding articles, conjunctions and prepositions. ## Where Is Case Conversion Useful? Case conversion can speed up the preparation of blog titles, page headings, social media copy, product catalogues, campaign names and presentation content. It is also useful when imported data contains inconsistent capitalisation or when text copied from another source does not match the required style. Developers and data teams may use case conversion when preparing identifiers, database values, test data or structured content. Editors can use it as an initial cleanup step before reviewing spelling, punctuation and style. Case conversion changes letter capitalisation rather than rewriting the content. It does not correct grammar, improve wording or determine whether proper names have been capitalised correctly. The converted result should therefore be reviewed before publication, especially when the text contains brand names, abbreviations or language- specific capitalisation rules. ## Private Conversion in Your Browser All conversion takes place locally in your browser. The entered text is not uploaded to a remote server or shared with third parties. Once the required style has been applied, the result is immediately available to copy. ## Track the digital heartbeat with Kriko Subscribe to receive curated insights, news, and ideas shaping the digital landscape.
