Reverse Text
Flip any text backwards, one character unit at a time.
This tool runs entirely in your browser. Your files are never uploaded to a server.
What this tool does
Type or paste any text to instantly see it reversed, with the last character now first and the first now last.
How to use it
Start typing in the box, or paste existing text — the reversed version appears immediately below, ready to copy. There's no button to press.
Worked example
Typing "Hello, world!" produces "!dlrow ,olleH" — every character, including punctuation and spaces, is flipped in place.
How the reversal works
The text is split into an array using JavaScript's basic string split, reversed, and rejoined — this operates on UTF-16 code units, the same building block JavaScript uses internally for strings.
Checking palindromes
If the reversed output matches the original text exactly (or matches after you separately lowercase it and strip spaces), the original is a palindrome — this tool doesn't do that comparison for you, but it produces the reversed text you'd compare against.
Limitations with emoji and accented characters
Most emoji and some rare CJK characters are stored as two UTF-16 code units (a "surrogate pair"). Reversing at the code-unit level splits that pair apart, which typically breaks the character into two invalid, unrenderable pieces rather than just displaying it "backwards" — this tool is best suited to plain ASCII or simple accented text, not emoji-heavy input.
Privacy
Reversal happens entirely in your browser as you type — nothing is uploaded to a server.
Frequently Asked Questions
- Does this reverse word order or characters?
- It reverses individual character units, not the order of words — so 'hello world' becomes 'dlrow olleh', not 'world hello'.
- Can I use this to check palindromes?
- Yes — if the reversed output matches the original text exactly (or after you separately normalize case and spaces), the original is a palindrome.
- Does it work correctly with emoji?
- Not reliably: most emoji are stored as two code units, and reversing at that level splits them apart into broken, unrenderable characters rather than a flipped emoji.
- Does it change letters, numbers, or punctuation differently?
- No, every character type — letters, digits, spaces, and punctuation — is treated identically and simply has its position flipped.
