Text Case Converter

Read full description

Convert text to any case in one tap. Paste a word, a variable name, a headline or a whole paragraph and get it back as UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, SCREAMING_SNAKE, slug, reversed or aLtErNaTiNg โ€” 12 cases, all generated at once. Most converters give you one result and make you start over for the next format. Text Case Converter shows every case at the same time, live, as you type. Tap the one you want and it is on your clipboard. On top of that sits a Tools tab with 20 text operations for the cleanup work that usually happens in a text editor: trimming, de-duplicating, encoding, sorting and counting. WHAT YOU GET - 12 cases computed at once from a single input โ€” tap any result to copy it - Developer naming done right: camelCase, PascalCase, snake_case, kebab-case, SCREAMING_SNAKE and URL slugs with accents folded out - 20 text tools: trim whitespace, collapse spaces, remove line breaks, strip accents, remove numbers, remove punctuation - Line work in bulk: sort A to Z, deduplicate, reverse order, add line numbers, wrap every line in quotes - Encode and decode Base64, escape and unescape HTML entities - Live word, character, line and sentence counts while you type PERFECT FOR - Developers naming variables, classes, constants, database columns and CSS classes - Writers and editors fixing a headline typed in caps lock or a paragraph pasted in the wrong case - Marketers and bloggers turning titles into clean URL slugs - Students and office workers tidying pasted text before it goes into a doc or a spreadsheet WHY NOT JUST USE A WEB CONVERTER Because pasting into a website means your text leaves your device, and because a browser tab gives you one format per visit. This app is offline, opens instantly, keeps a history of your last 50 transformations so you can recover something you already copied, lets you star the ones you reuse, and remembers your draft between launches. A Reference tab explains what each naming convention is and where it is actually used, so you pick the right one the first time. PRIVACY Every transformation runs on your iPhone. No account, no sign-in, no ads, no tracking of your content. Your text is never uploaded anywhere. FULL ACCESS Full Access unlocks all 12 cases, all 20 text tools, unlimited history and favorites, and the complete case reference library. It is available as a weekly plan, a yearly plan, or a one-time lifetime purchase โ€” pick the one that fits, and cancel anytime on the subscription plans. Paste your text, tap the case you need, and get back to work.
