About this reverse text generator
The reverse text generator offers five distinct reversal modes. Character reversal walks the input as Unicode grapheme code points (so emoji and multi-byte characters reverse cleanly without being broken into surrogate halves). Word, sentence, and line reversal keep punctuation and whitespace in place while flipping the order of the named unit. The upside-down flip is a character-substitution effect that swaps each letter for its closest visually-rotated Unicode counterpart and then reverses the string, so the result reads as if the page were turned 180°.
A concrete example. Input: `"Hello world! How are you?"`.
- Reverse characters → `?uoy era woH !dlrow olleH` - Reverse word order → `you? are How world! Hello` - Reverse sentence order → `How are you? Hello world!` - Flip upside-down → `¿noʎ ǝɹɐ ʍoH ¡plɹoʍ ollǝH`
This is handy for puzzles, stylistic social-media posts, generating test data that exposes string-handling bugs, or quickly checking whether a substring reads the same forwards and backwards. All processing runs in your browser.
FAQ
- Does character reversal handle emoji correctly?
- Yes. The character mode uses `Array.from(text)` which iterates over Unicode code points rather than UTF-16 code units, so an emoji like 🌍 is reversed as one unit instead of being split into its surrogate pair.
- How is sentence order detected?
- Sentences are detected by splitting on runs of `.`, `!`, or `?` followed by whitespace. Each sentence keeps its trailing punctuation, so reversing the sentence order does not mangle the punctuation.
- Why does upside-down flip leave some characters unchanged?
- The flip uses a fixed mapping of letters, digits, and common punctuation to their Unicode upside-down equivalents. Characters that have no upside-down counterpart (for example most non-Latin scripts) are passed through unchanged.
- Will reversed text display correctly in any app?
- The character, word, sentence, and line modes produce plain text that displays anywhere. The upside-down mode relies on Unicode characters that some older fonts may render as boxes; modern browsers and OS fonts render them correctly.
- Can I use this to check for palindromes?
- You can paste a word and run "reverse characters" to compare visually, but for proper palindrome checking (which ignores case, spaces, and punctuation) use our dedicated palindrome checker.
- Is my text uploaded anywhere?
- No. The tool runs entirely in your browser. Your text is never sent to a server, logged, or stored.
