Every Way to Reverse Text in One Tool
Array.from() for Unicode safety — emoji and multi-byte characters (accented letters, CJK) are treated as single grapheme units rather than being split into surrogate pairs.LazyTools vs Other Text Reversers

Text Reversal — Uses, Examples and Technical Notes
Common uses for text reversal
Text reversal has more practical applications than it might first appear. Developers use character reversal to verify palindromes (strings that read the same forwards and backwards — “racecar”, “level”, “Was it a car or a cat I saw?”). Programming courses use “reverse words in a string” as a common interview question testing knowledge of string manipulation and array methods. Content creators use upside-down text for social media posts and usernames. Security professionals use leet speak to test password strength since many password validators allow letter-to-number substitutions. Log analysis tools often need line reversal to show the most recent entries at the top.
Unicode safety in text reversal
Naïve character reversal using str.split('').reverse().join('') breaks on emoji and certain Unicode characters. These use surrogate pairs — two JavaScript string characters representing one Unicode code point. Reversing the array splits the pair and produces garbled output. This tool uses Array.from() which correctly handles surrogate pairs, treating each Unicode code point as a single element. The upside-down text mode also handles multi-byte input safely using the same approach.
The “reverse words in a string” interview problem
One of the most common string manipulation interview questions asks candidates to reverse the order of words in a sentence without using built-in reverse functions. The solution typically involves: split on whitespace, reverse the resulting array, join with spaces. Edge cases to handle include multiple consecutive spaces (which this tool preserves), leading/trailing spaces and strings with only one word. The “Reverse word order” mode demonstrates the expected output for any test case you need to verify.
Frequently Asked Questions
Paste or type text into the input box. The reversed output appears instantly. Choose from 7 modes: reverse characters, word order, lines, each word, each line, upside-down or leet speak. Copy or download the result.
Select “Reverse word order”. Each word stays intact but the sequence is reversed. “The quick brown fox” becomes “fox brown quick The”. Use “Reverse each word” to reverse letters within each word instead.
Unicode characters that resemble rotated Latin letters. The text is also reversed so rotating your screen 180 degrees makes it readable. Works in social media, messaging apps and usernames anywhere Unicode is supported.
Letter-to-number substitution from internet/hacker culture: a=4, e=3, i=1, o=0, t=7, s=5. So “elite” becomes “3l173”. Used for usernames, creative passwords and internet culture references.
Yes. The character reversal mode uses Array.from() which handles Unicode surrogate pairs correctly — emoji and multi-byte characters are treated as single units rather than being split into garbled output.
Paste text, choose a mode and the output appears live. 7 modes: reverse chars, words, lines, each word, each line, upside-down, leet speak. Copy or download .txt. Free, browser-side, nothing uploaded.
Select “Reverse lines”. The line order is reversed (line 1 becomes the last line) while each line’s content is preserved. Useful for reversing log files, numbered lists or poem stanzas.
Mirror text is the same as character reversal — the entire string read backwards. It looks like text reflected in a mirror. “Hello World” becomes “dlroW olleH”. Some also use the term for upside-down text which uses Unicode flipped characters.
