Upside down text generator

There is no "rotate" command for plain text that survives copy and paste, so the generator fakes it in two steps:

1. Swap each letter for a Unicode character that looks like that letter turned 180 degrees.
2. Reverse the order of the characters, because turning a line upside down also puts its last letter first.

So hello world becomes plɹoʍ ollǝɥ. Turn your screen around and it reads normally again. The trick works because many turned letters already exist in Unicode: linguists use them in the International Phonetic Alphabet, and they sit mostly in the IPA Extensions block (U+0250–U+02AF), which phones and computers have supported for a long time.

Letter	Flipped	Where it comes from
a	ɐ	turned a, a phonetic letter
b / q	q / b	the letters simply swap
c	ɔ	open o, a phonetic letter
d / p	p / d	swap
e	ǝ	turned e
h	ɥ	turned h
m	ɯ	turned m
n / u	u / n	swap
r	ɹ	turned r
t	ʇ	turned t
v, w, y	ʌ, ʍ, ʎ	turned v, w, y
o, s, x, z	o, s, x, z	already look the same upside down

Lowercase letters flip most convincingly. Turned capitals are patchier in Unicode and in fonts, so a flipped all-caps word may look less even than the same word in lowercase.

Accents are dropped: é is flipped as a plain e, because an accent mark would land in the wrong place once the letter is turned.

These three effects are easy to mix up:

• Upside down (this page): turned letters plus reversed order, readable when you rotate the screen.
• Reversed: the same letters in backward order, like olleh, with no turning. Use the reverse text tool for that, or to reverse word order instead of letters.
• Mirrored: letters flipped left to right, as on the front of an ambulance. That needs an image or a design app, because few letters have mirrored Unicode twins.

People use upside-down text for jokes ("my day has been..." followed by a flipped word), Australia puns, puzzle clues, and bios that make visitors tilt their head.

The compatibility marks next to the result cover Instagram, TikTok, Discord, Facebook and X, and say whether the text should work or may break, meaning empty boxes on some devices or the app trimming it. They are estimates based on when the characters were added to Unicode and on fonts that common devices ship, so treat them as a guide; platforms change.

Most turned letters are long-established phonetic characters, so they usually display. As with any special characters, you can't use them in an @username, and Facebook won't accept them in your profile name. Posts, comments and chats are fine.

A sighted reader sees a playful upside-down sentence. A screen reader sees a backward row of phonetic letters and may read it as "p, l, latin small letter turned r, o, latin small letter turned w..." or skip it. Since the order is reversed too, even a perfect letter-by-letter reading would come out backward. Use the How a screen reader may hear it toggle to see the character names for yourself.

Keep the flipped part short and make sure your post still makes sense without it. The counter shows characters and UTF-16 code units, handy if you are fitting a flipped line into a 150-character Instagram bio. All processing happens in your browser.
