Frequently asked questions
What does invert case mean?
Invert case means every uppercase letter becomes lowercase and every lowercase letter becomes uppercase. For example, "HeLLo" becomes "hEllO".
Is the Invert Text Case Converter free?
Yes. It is free with no signup and no limits.
Can it fix text typed with caps lock on?
Yes. If you typed "tHIS SENTENCE" with caps lock on, inverting the case gives you "This sentence" back.
Does it change numbers or punctuation?
No. Numbers, punctuation, spaces, and symbols stay exactly the same. Only letters change.
What is the difference from alternating caps?
Inverting flips each letter to its opposite case. Alternating caps forces a strict upper-lower-upper pattern regardless of the original case.
Is my text sent to a server?
No. The conversion runs in your browser with JavaScript, so your text never leaves your device.
