This page explains what inverse case is, when to use it, how the tool works, and answers the most common questions about case conversion.
What is an Inverse Case?
Inverse case is a text format where the capitalization of every letter is flipped. Every converted to uppercase, and every converted to lowercase. Spaces, numbers, and punctuation stay exactly as they are, only the letters change.
Here are two clear examples:
- Before: This is an Example Sentence. After: tHIS IS AN eXAMPLE sENTENCE.
- Before: hello WORLD, how ARE you? After: HELLO world, HOW are YOU?
You may also see this called toggle case, both names describe the exact same transformation. Each letter is toggled individually based on its current state, not based on its position in a word or sentence.
This is different from other case types. When you use a title case converter or a sentence case converter, the rules are based on word position. With inverse case, there are no positional rules, every letter simply becomes the opposite of what it currently is.
