Text Case Converter Title, Sentence, UPPER & lower Case
Convert text between UPPERCASE, lowercase, Title Case, Sentence case, and Alternating case.
5 Case Modes
UPPERCASE, lowercase, Title Case, Sentence case, Toggle case, and Alternating case — all with one click and live real-time conversion as you type.
Highlight View
Switch to Highlight mode to see every changed character highlighted — uppercase letters in red, lowercase in blue — so you can visually review every transformation.
Case Distribution Bar
A live proportional bar shows the balance between uppercase, lowercase, and other characters in the output — changes in real time with every keystroke.
All Languages + RTL/LTR
Unicode-aware — Arabic, English, Greek, Cyrillic, Hebrew, and all other scripts. RTL/LTR toggle for correct display direction per language.
Live Stats
Real-time: characters, words, uppercase count, lowercase count, changed chars, and line count — all update as you type or switch modes.
Instant — No Button
Conversion happens as you type. Switch modes by clicking the case cards — the result updates in milliseconds with no manual trigger needed.
