About this tool
Flip your text upside down and backwards using mathematical Unicode character mappings for creative styling.
Upside Down Text rewrites what you type into rotated Unicode look-alikes — 'a' becomes 'ɐ', 'E' becomes 'Ǝ', '?' becomes '¿' — and reverses the character order so the result reads correctly when the whole line looks flipped. It covers a–z, A–Z, 0–9 and common punctuation, and adds four more styles from the same box: Bubble Text (ⓐ), Block Text (🄰), Mirror/Reverse, and Leetspeak (a→4, e→3, o→0). The output is plain text you can paste anywhere that accepts Unicode, so it survives in bios, usernames and messages without any image or font.
Open Upside Down Text on AltFTool — it loads instantly in your browser.
Type or paste into the "Normal Input Text" box — characters with no mapping, such as emoji or accents, pass through unchanged.
Choose a style: Upside Down, Bubble Text, Block Text, Mirror/Reverse or Leetspeak; in Upside Down mode, untick "Reverse Character Order" to flip glyphs in place.
The "Styled Flipped Output" box updates as you type — press Copy to take the plain Unicode text into a bio, username or message.
A toggle lets you flip the glyphs while keeping the original left-to-right order, which is what you want when a platform reverses the string for you.
Upside Down, Bubble, Block, Mirror and Leetspeak all read from the same text box, so you can compare them without retyping.
Any character with no mapping — an emoji, an accent, a symbol outside the table — is passed through unchanged instead of being deleted or replaced with a box.
It substitutes each character for a different Unicode character that happens to look like the rotated version, then reverses the string. There is no rotation happening — 'ɐ' is U+0250, a real letter used in phonetic notation, not an 'a' turned 180 degrees.
Usually yes, because the output is ordinary Unicode text rather than an image. Some platforms strip unusual characters from display names or fall back to a box glyph if the device font lacks one, so paste it in and check before you save.
Turn it off when the destination already reverses or renders the line for you, or when you want each letter flipped in place while the reading order stays normal. With it on, the characters are flipped and then the whole string is reversed so the sentence reads correctly upside down.
All 26 lowercase and 26 uppercase letters, the digits 0–9, and punctuation including . , ' " ? ! ( ) [ ] { } < > & _ ; ` - +. A few have no true flipped counterpart, so H, I, O, S, X, Z, 0 and 8 map to themselves, and anything unmapped is left as-is.
