Everything happens locally in your browser. Your text is never sent to any server. Each character is replaced with the closest-looking upside-down character, and the order is reversed. It is a visual trick, not a real 180° rotation of the letterforms. Both boxes work in either direction, so flipped text pasted into the second box flips back to normal in the first.
Flip Text Examples

These are flipped with the exact same tool above, so paste any of them into the input to watch them flip back to normal text.
Who invented Flip Text?
There's no single named inventor. It started with a Reddit post cataloguing Unicode characters that happen to look like upside-down letters. fliptext.org then expanded that character set and packaged it into the first proper flip-text application. Every other flip-text site that followed is built on the same character mapping it popularized, while fliptext.org, and now this app, are the original.
Why is it possible to flip letters at all?
Unicode, the character set behind virtually all modern text, happens to include characters from other alphabets and phonetic systems that visually resemble upside-down Latin letters. For example, the letter "e" flipped looks like the character "ǝ". Flip Text swaps each letter for its closest such look-alike and reverses the order of the text, so the whole line reads correctly when turned 180 degrees. It's a clever substitution trick, not an actual rotation of the letterforms.
Why doesn't Flip Text work with all letters?
Not every letter has a natural upside-down look-alike somewhere in Unicode. Some shapes simply don't have a mirrored counterpart that looks convincing when flipped. For those characters, the closest available approximation is used instead, which is why a few letters, numbers, or symbols can look slightly different from what you'd expect after flipping.
Why doesn't fliptext.org exist anymore?
Because the application now lives here. Flip Text is one of the tools on ToolsByTek.com, so keeping a separate standalone domain running just for it no longer made sense.
