Free Case Converter — Upper, Lower, Title & Sentence Case
Instantly convert any text with our free case converter: UPPERCASE for headings and warnings, lowercase for normalized slugs and code, Title Case for blog headlines and book titles, Sentence case for clean prose, aLtErNaTiNg for playful memes, and iNVERSE for fixing accidental Caps-Lock disasters. Writers paste messy drafts, developers normalize labels, students repair essays, and social media managers restyle captions — all in a single click without retyping a single word.
The tool shows live word and character counts beneath the editor so you can watch limits for tweets, meta titles and ad headlines as you convert. Title Case capitalizes every major word while Sentence case lowercases everything except the first word of each sentence, matching standard publishing conventions. Alternating and inverse modes transform character-by-character for stylistic effects. When you are done, copy the result to your clipboard or download it as a plain-text file for offline use.

When to use each case
Use UPPERCASE sparingly for short warnings since full caps read as shouting; Title Case for post headlines and video titles; Sentence case for body copy and emails; lowercase for URLs, hashtags and code identifiers. Never submit essays in alternating case — reserve it for memes and jokes.
