String Reverse
Reverse any string of text and check for palindromes.
Reversing text has practical uses in programming, puzzles, and data manipulation. Developers use string reversal to check for palindromes, solve algorithm challenges, or process text in reverse order. This free string reverser can reverse a full string character by character, reverse the order of words in a sentence, or reverse the order of individual lines.
How to use this tool
- Paste or type the text you want to reverse.
- Choose the reversal mode: reverse characters, reverse word order, or reverse line order.
- The reversed text appears immediately. Click Copy to save it to your clipboard.
Frequently asked questions
What is a palindrome?
A palindrome is a word, phrase, or sentence that reads the same forwards and backwards (ignoring spaces and punctuation). Examples: "racecar", "A man a plan a canal Panama". Reversing a string and comparing it to the original is one way to detect palindromes.
How is string reversal used in programming?
String reversal is a classic coding interview question. It tests knowledge of loops, arrays, and two-pointer techniques. It is also used in real applications for text encoding and certain algorithms.
Can I reverse word order without reversing characters?
Yes — this tool supports reversing word order separately from character order. Select "Reverse Words" mode to flip the order of words while keeping each word's letters intact.
What does reversing lines do?
Reversing lines flips the order of newline-separated lines in your text. This is useful when you have a list and want the last items first — for example, reversing a dated log file.
