Text Reverser — Reverse String, Words, Sentences, Lines (Online)
Reverse any text — by character, word, sentence, or line. Unicode-aware (handles emoji, accents). Free, in-browser, no length limit.
About Text Reverser
A text reverser is a tool that flips the order of characters, words, sentences, or lines in a string. The ZTools Text Reverser is Unicode-aware (handles emoji, combining accents, and right-to-left scripts correctly using `Intl.Segmenter`), supports four reversal modes, and runs entirely in your browser. Useful for puzzle-solving, palindrome checking, RTL preview testing, generating mirror-image text for design mockups, or just learning how Unicode grapheme clusters work.
Use cases
- Checking whether a phrase is a palindrome. Type a candidate ("racecar", "A man a plan a canal Panama"), reverse it, compare to the original (case-insensitive, ignore spaces). The character-mode reverser produces the bit-for-bit reverse needed for the comparison.
- Generating decorative reversed text for design mockups. Mirrored text for posters, t-shirts, and tattoos. Reverse "STRENGTH" to "HTGNERTS" — the visual impact for graphic design. Note: this is character reversal, not glyph mirroring; use a mirroring filter in your design tool for true visual mirroring.
- Testing right-to-left (RTL) layout in i18n work. For locales like Arabic, Hebrew, and Persian, your UI must support RTL text flow. Reverse a sample phrase to simulate how Latin-script text would appear in an RTL context, useful for layout debugging.
- Word-order reversal for parody and creative writing. Switch reverser mode to "Words" — "The quick brown fox" becomes "fox brown quick The". Combined with sentence-level reversal, generates Yoda-style transpositions for parody content.
How it works
- Paste text into the input pane. Any length — paragraphs, multi-line text, Unicode strings with emoji and accents.
- Choose reversal mode. Characters (every grapheme reversed), Words (word order reversed, words intact), Sentences (sentence order reversed), Lines (line order reversed).
- Click Reverse. The tool uses `Intl.Segmenter` to split text into grapheme clusters, words, or sentences according to Unicode rules — so emoji like 👨👩👧 stay intact instead of being split into surrogate halves.
- Review the output. Output appears in the right pane. Character counts shown for both input and output (should match unless your input had trailing whitespace).
- Copy or download. One-click copy. Original input stays available for re-reversing with different settings.
Examples
Input: Hello, World! 👋
Output: 👋 !dlroW ,olleH
Character mode. Emoji is preserved as a single grapheme cluster — not split into halves.
Input: The quick brown fox jumps
Output: jumps fox brown quick The
Word mode. Words reversed, internal characters intact.
Frequently asked questions
Will reversing emoji break them?
No — the tool uses `Intl.Segmenter` to identify grapheme clusters. Compound emoji like 👨👩👧👦 stay together; the cluster is moved as a unit.
Does the reverser handle accented characters correctly?
Yes. A character with a combining accent (e.g., `é` as `e` + combining acute) stays bound to its base character through the reversal. Without grapheme-cluster awareness, naive reversal would put the accent on the wrong character.
What about right-to-left scripts like Arabic?
RTL scripts have their own native logical order independent of visual presentation. Reversing them produces correct logical-order reversal but may look "wrong" in the visual flow because the original was already presented right-to-left.
Is the reversal lossless?
Yes for character mode (reversing twice returns the original). For sentence and line modes, intervening whitespace and punctuation are preserved positionally — a double-reverse is still lossless.
Can I reverse very long text?
Yes — handles inputs up to ~10 MB. Beyond that, browser memory becomes the bottleneck.
Does it work offline?
Yes. Once loaded, the page works without network. Open DevTools → Network and confirm zero requests during reversal.
Pro tips
- Use character mode for palindrome checking and pure visual reversal.
- Use word mode for parody, Yoda-style transpositions, and word-order experiments.
- For mirror-image visual reversal in design, combine character reversal with a CSS `transform: scaleX(-1)` filter.
- When working with i18n RTL, prefer your framework's native RTL flag over manual reversal.
