Text Reverser
Reverse characters, words or lines — without destroying emoji, flags or Indic script.

How to use Text Reverser
Paste your text
Any script, any length. It is reversed in this browser tab.
Choose what to reverse
Characters flips the whole thing. Word order keeps each word readable but flips the sequence. Characters-within-words does the opposite.
Copy the result
Reversing the output again returns the original exactly.
Why use this text reverser
Runs on your device
Your input is handled entirely in this browser tab. Nothing is uploaded, so there is nothing for us to store, log or leak.
No sign-up, no quota
No account, no daily limit, no watermark and no email wall. Use it once or two hundred times a day.
Built to be linked
Options are stored in the URL, so a configured tool is a link you can send to a colleague or bookmark.
Technical notes
Reversal is the operation where the standard JavaScript one-liner is most visibly wrong, and almost every tool online uses it. Splitting a string on code points breaks anything built from more than one — emoji, flags, and Indic consonant clusters. The comparison below was produced by running both implementations on the same input.

Naive code-point reversal versus grapheme clusters — measured, not asserted
| Input | Naive reverse | This tool |
|---|---|---|
| 👨👩👧👦 | 👦👧👩👨 (different people) | 👨👩👧👦 (unchanged — one character) |
| 🇧🇩 | 🇩🇧 (a different flag) | 🇧🇩 (unchanged) |
| नमस्ते | ेत्समन (broken clusters) | स्तेमन (clusters intact) |
| éclair | rialće (accent moved) | rialcé (accent stays) |
Supported
- Grapheme-cluster reversal via Intl.Segmenter
- Emoji sequences, including ZWJ families and skin-tone modifiers
- Regional indicator pairs (flags)
- Combining marks and Indic conjuncts
- Five reversal modes, all of which round-trip exactly
Limits and trade-offs
- Not mirrored or upside-down text — that substitutes different glyphs and is a separate tool.
- Right-to-left scripts are reordered correctly but the display algorithm may re-reorder them, so the visual result can be confusing.
- Cluster boundaries follow the browser's Unicode version, so a very old browser may segment a brand-new emoji differently.

Frequently asked questions
Why do other reverse tools break emoji?
They use the JavaScript one-liner `[...text].reverse().join("")`, which splits on code points. A family emoji is seven code points joined by zero-width joiners, so reversing them produces a different arrangement of people. This tool splits on grapheme clusters — what a reader would call a character — so it stays intact.
What is a grapheme cluster?
One user-perceived character, which may be several code points. "é" can be one code point or "e" plus a combining accent; a flag is two regional indicators; "नमस्ते" is six code points forming four clusters. Reversing anything smaller than a cluster corrupts the text.
Does reversing twice give me back the original?
Yes, exactly — for every mode. That is a useful check: if a reverse tool does not round-trip your text, it is splitting at the wrong boundary and has already damaged it.
Will this produce mirrored or upside-down text?
No. This reverses the order of characters; it does not substitute mirrored glyphs. "abc" becomes "cba", not "ɔqɐ". Those are different operations and mixing them silently would be wrong.
Does it work with Arabic and Hebrew?
The characters are reordered correctly, but be aware that right-to-left scripts already display in reading order — so reversed RTL text may look unchanged in some contexts because the display algorithm reorders it again.
