Questions people ask
How do I turn ALL CAPS text back to normal?
Paste it here — lower case is already selected, so it converts the instant you paste. If you want the first letter of each sentence capitalised too (not just everything lowercased), tap the Sentence case option next to it instead.
Why did my Caps Lock text happen in the first place?
Almost always a stuck or accidentally-enabled Caps Lock key while typing in a chat, form or document — a common enough accident that "uppercase to lowercase converter" is one of the most searched utility phrases online.
Does converting to lowercase fix punctuation and spacing too?
No — only letter casing changes. Punctuation, spacing, line breaks and paragraph structure are left exactly as they were, so nothing else about your text is altered.
Will this work on Hindi or other non-Latin text mixed in?
Yes — scripts without letter case, like Devanagari, pass through completely unchanged, while any Latin letters in the same text are correctly lowercased using your browser's Unicode-aware casing rules.
Is anything I paste here sent to a server?
No. The whole tool is JavaScript running in your browser, and this site has no endpoint that accepts text. That matters when what you are pasting is a real API payload, a customer record, or a password.
