Reverse Text

What is the Reverse Text tool?

The Reverse Text tool flips your writing back to front in whatever sense you mean by "reverse". Drop in a word, a sentence, a list, or a whole paragraph, and choose one of four reversal modes: reverse the characters, reverse the order of the words, reverse the characters inside each line, or flip the order of the lines. The result appears live as you type, and a single tap copies it. It is the quickest way to turn Hello world into dlrow olleH, to flip a phrase into backwards text for a puzzle or a username, or to invert a numbered list without retyping it.

Everything happens in your browser, so even private text stays on your device. The text you paste is never uploaded, logged, or saved, which matters when you are reversing a draft note, a passphrase, or anything you would rather not hand to a stranger's server.

How to use it

1. Type or paste your text into the top box.
2. Pick a reversal mode with the radio buttons — reverse characters, reverse word order, reverse each line, or flip line order.
3. Read the result in the lower box; it updates the instant you type or switch modes.
4. Press Copy to take the reversed text with you, then close the tab. The whole flow is paste, reverse, copy, leave.

The four modes

• Reverse characters — flips the entire string end to end; newlines are reversed too, so a block reads completely backwards.
• Reverse word order — keeps every word spelled correctly but flips their sequence, so the last word comes first.
• Reverse each line — reverses the characters within every line while keeping the lines in their original top-to-bottom order.
• Flip line order — leaves each line untouched but puts the last line first, like turning a stack upside down.

How Unicode-safe reversal works

Reversing text sounds trivial until you reverse an emoji. A naive reverser splits a string into UTF-16 code units and flips the array. That destroys anything built from more than one unit: most emoji are surrogate pairs, flags and skin-tone variants are multi-emoji sequences, and an accented letter like é may be a base letter plus a combining mark. Flip those blindly and you get scrambled boxes, the wrong skin tone, or an accent that jumps onto the wrong letter.

This tool reverses by grapheme — a user-perceived character — using the browser's built-in Intl.Segmenter with grapheme granularity. Each emoji, flag, accented letter, or CJK character is treated as one indivisible unit, so it survives the flip intact. On the rare older browser without that feature, the tool falls back to a code-point split, which still keeps most emoji whole. The upshot is that your thumbs-up emoji, your café, and your Japanese characters come out the right way round, not as broken fragments.

Worked example

Take a short input that mixes plain letters, an emoji, and an accent — a greeting, a waving hand, and the word café:

• Reverse characters, done grapheme-safe, keeps the waving hand emoji and the accented letter whole while flipping the whole string end to end.
• A naive character reverser would instead produce a broken hand emoji and a stray accent on the wrong letter — exactly the bug this tool avoids.
• Reverse word order keeps each word spelled correctly and simply puts the last word first.

Common use cases

• Making backwards text for usernames, puzzles, riddles, or playful social posts.
• Reversing word order to test a phrase, build a mirror caption, or check a palindrome.
• Flipping the order of a log or a numbered list so the newest line sits on top.
• Creating mirror-style ASCII layouts by reversing each line.
• Reversing strings full of emoji or accented names without breaking them.

Why use this one

Many sites can reverse a plain ASCII string; far fewer do it correctly for the text people actually paste today, which is full of emoji, accents, and non-Latin scripts. This tool combines four distinct modes, grapheme-correct reversal, instant live output, one-tap copy, and a strict no-upload privacy promise — all on a page that loads fast on a phone with no account required.

It is part of a small, focused text toolkit, and each tool has a clear job. To tidy stray spaces before or after reversing, the Text Formatter collapses double spaces and trims lines without touching word order. To change capitalization, the Case Converter switches between UPPERCASE, lowercase, and Title Case. And to join wrapped lines into one continuous paragraph, Remove Line Breaks is built for exactly that.
