Reverse Text
Reverse text by characters, words, or lines instantly in your browser.
About the Reverse Text
The Reverse Text tool flips your text backwards in three different ways: it can reverse the individual characters of a string, reverse the order of the words, or reverse the order of the lines. Everything runs live in your browser as you type or paste, so there is no upload, no waiting, and no limit on how much text you can process. Nothing you enter ever leaves your device.
Reversing text is handy for more than novelty. Character reversal is a quick way to create mirror-style strings, puzzle answers, and simple obfuscation, or to test whether a routine correctly handles right-to-left and Unicode content. Reversing word order helps you rethink a sentence, build word games, or check the structure of a phrase. Reversing line order is genuinely useful when you want the newest entry of a log at the top, need to flip a list, or want to invert a stack of items you pasted in the wrong direction. Because the output updates instantly, you can switch modes and immediately see the difference.
How to use
- Pick a reverse mode. Choose Reverse characters to flip the whole string end to end, Reverse words to reverse the order of the words, or Reverse lines to reverse the order of the lines. Only one mode is active at a time.
- Type or paste your text into the Input box. The Output box updates on every keystroke and whenever you change the mode.
- Read the result in the Output box. It is read-only so your reversed text stays intact while you review it.
- Copy or clear when you're done — "Copy result" places the reversed text on your clipboard, and "Clear" empties the input to start fresh.
A few details worth knowing about how each mode works:
- Reverse characters is Unicode-aware. It splits the text into whole characters (code points) before flipping, so emoji and accented letters made of surrogate pairs are not broken apart into garbled fragments.
- Reverse words keeps the whitespace between words in place while reversing their order, so single spaces, tabs, and line breaks that separated the words are preserved in the flipped output rather than collapsed.
- Reverse lines splits on line breaks and reverses the blocks, which is the fastest way to turn a top-to-bottom list into a bottom-to-top one without retyping anything.
Everything happens on your device in plain JavaScript, which is why it works offline once the page has loaded and stays fast even on very long inputs.
Frequently asked questions
Is my text uploaded or saved anywhere?
Never. All reversing happens locally in your browser on your device. The text is not sent to a server, stored, or logged — close the tab and it's gone. That makes the tool safe for private notes, drafts, and anything else you'd rather not share.
What's the difference between reversing characters, words, and lines?
Reversing characters flips every character so "hello" becomes "olleh". Reversing words keeps each word intact but reverses their order, so "one two three" becomes "three two one". Reversing lines keeps each line intact but flips their top-to-bottom order, which is ideal for lists and logs.
Will reversing characters break emoji or accented letters?
No. The character mode is Unicode-aware and splits the text into whole code points before flipping, so emoji and characters built from surrogate pairs stay in one piece. Note that some complex sequences, like a family emoji joined by zero-width joiners, may still separate because they are technically several code points.
Does it work with right-to-left languages like Arabic or Hebrew?
The tool reverses the underlying character sequence. Your browser then applies its own bidirectional display rules, so visually reversed right-to-left text can look different from what you might expect. It's reliable for logical character order but not a substitute for a proper bidi editor.
Is there a length limit?
No. Because the tool runs entirely in your browser, you can reverse a single word or an entire document. Extremely large inputs may briefly pause while processing, but there is no hard cap on length.
Why is the output box read-only?
The output is generated from your input, so it's locked to prevent accidental edits that would be overwritten on your next keystroke. To change the result, edit the Input box or switch the reverse mode, then use "Copy result" to grab the reversed text.
