What each reversal type is for
Reverse characters: flips the entire text backwards, letter by letter ("Hello" becomes "olleH"). Reverse word order: keeps each word intact, only changing their position in the sentence. Reverse letters in each word: keeps the word order, but reverses the letters within each one.
Reverse lines: useful for multi-line text, flipping the order lines appear in without changing each line's content. Upside down text: swaps each letter for a Unicode character that looks flipped upside down, and reverses the text order, creating a fun effect for social media and messages.
Limitations of upside down text
Not every letter or symbol has an exact flipped Unicode equivalent — results work best with lowercase letters, numbers, and basic punctuation. Uppercase letters are converted to lowercase before flipping, since most don't have a matching flipped glyph.
