Text Reverser

Free online tool to reverse text in various ways.

🛠️ Reversal Mode

📝 Input Text

✨ Reversed Text

Reverse text in multiple ways: entire text in reverse order, individual words while maintaining word order, or completely reversing line order.

📚 Examples

Entire Text Reversal:
Hello World → dlroW olleH
Words Reversal:
Hello World → olleH dlroW
Lines Reversal:
Line 1 Line 2 Line 3 → Line 3 Line 2 Line 1

Key Features​

  • Reverse Entire Text: Arrange all characters in reverse order
  • Reverse Each Word: Reverse each word individually
  • Reverse Line Order: Change line order to reverse
  • Swap Function: Quick exchange between input and output
  • Instant Processing: See results immediately as you type
  • Examples Provided: Display examples for each mode

How to Use​

Basic Usage​

  1. Enter text in the input area
  2. Select a reversal mode:
    • Reverse Entire Text: All characters in reverse order
    • Reverse Each Word: Reverse each word individually
    • Reverse Line Order: Lines in reverse order
  3. Reversed results are displayed automatically

Button Usage​

  • Copy: Copy results to clipboard
  • Swap: Exchange input and output (useful for double reversal)
  • Reset: Clear all content

Reversal Mode Explanation​

1. Reverse Entire Text​

Completely reverses all characters. Spaces, newlines, and special characters are all reversed.

Input: Hello World
Output: dlroW olleH
Input: 안녕하세요
Output: 요세하녕안
Input: 123 ABC !@#
Output: #@! CBA 321

Use Cases:

  • Simple encryption/obfuscation
  • Fun text effects
  • Creating mirror text
  • Palindrome verification

2. Reverse Each Word​

Reverses each word individually but maintains word order. Spaces are preserved.

Input: Hello World
Output: olleH dlroW
Input: The quick brown fox
Output: ehT kciuq nworb xof
Input: 안녕하세요 친구들
Output: 요세하녕안 들구친

Use Cases:

  • Word games or puzzles
  • Text encryption (maintaining word structure)
  • Language learning tools
  • Fun text transformation

3. Reverse Line Order​

Leaves content of each line as is and only reverses the line order.

Input:
Line 1
Line 2
Line 3

Output:
Line 3
Line 2
Line 1
Input:
첫 번째 줄
두 번째 줄
세 번째 줄

Output:
세 번째 줄
두 번째 줄
첫 번째 줄

Use Cases:

  • Sort log files in reverse (latest items on top)
  • Reverse time order
  • Change list order
  • Data reorganization

Practical Application Examples​

1. Palindrome Verification​

Use to check if something is a palindrome:

Input: racecar
Output: racecar (if same, it's a palindrome!)

Input: hello
Output: olleh (if different, not a palindrome)

2. Simple Encryption​

Input: secret message
Output: egassem terces

The recipient can recover the original by reversing with the same tool

3. Log File Sorting​

When you want to see the latest logs first:

Input:
2024-01-01: Started
2024-01-02: Processing
2024-01-03: Completed

Output:
2024-01-03: Completed
2024-01-02: Processing
2024-01-01: Started

4. Word Games​

Input: LISTEN
Output: NETSIL

Game of making different words with input and output spelling
(Similar to LISTEN ↔ SILENT)

5. Fun Text Effects​

Input: Hello Friend
Reverse Each Word: olleH dneirF
Reverse Entire Text: dneirF olleH

Multilingual Support​

This tool perfectly supports all languages:

Korean​

Input: 안녕하세요 반갑습니다
Reverse Entire Text: 다니습갑반 요세하녕안
Reverse Each Word: 요세하녕안 다니습갑반

Japanese​

Input: こんにちは
Reverse Entire Text: はちにんこ

Chinese​

Input: 你好世界
Reverse Entire Text: 界世好你

Emoji​

Input: Hello 😊 World 🎉
Reverse Entire Text: 🎉 dlroW 😊 olleH

Utilizing Swap Function​

Using the swap button allows you to move output back to input:

1. Input: Hello World
   Output: dlroW olleH

2. Click [Swap]

3. Input: dlroW olleH
   Output: Hello World

Use Cases:

  • Recover original with double reversal
  • Experiment with various mode combinations
  • Encryption/decryption testing

Utilizing Mode Combinations​

Reverse Entire Text + Reverse Each Word​

Original: Hello World

Step 1 (Reverse Entire Text): dlroW olleH
Step 2 (Swap then Reverse Each Word): Wlrod Hella

Reverse Line Order + Reverse Entire Text​

Original:
Apple
Banana
Cherry

Step 1 (Reverse Line Order):
Cherry
Banana
Apple

Step 2 (Swap then Reverse Entire Text):
elppA
ananaB
yrrehC

Algorithm Explanation​

Reverse Entire Text​

inputText.split('').reverse().join('')
  1. Split string into character array
  2. Reverse array order
  3. Join back into string

Reverse Each Word​

inputText
  .split(/(\s+)/)  // Split including spaces
  .map((part) => {
    if (/\s/.test(part)) return part;  // Keep spaces as is
    return part.split('').reverse().join('');  // Reverse only words
  })
  .join('');

Reverse Line Order​

inputText.split('\n').reverse().join('\n')
  1. Split by lines
  2. Reverse array order
  3. Join back together

Performance​

  • Processing Speed: O(n) - proportional to character count
  • Memory Efficient: Uses minimal memory
  • Real-time Processing: Reverse immediately upon input

Frequently Asked Questions​

Q: Can emojis be reversed?​

Yes. All Unicode characters are supported, so emojis can be reversed too.

Q: How are newlines handled?​

  • Reverse Entire Text: Newlines are also reversed
  • Reverse Each Word: Newlines are preserved as is
  • Reverse Line Order: Newlines are used as delimiters

Q: Does reversing twice return to the original?​

Yes. Reversing twice with the same mode recovers the original. Use the swap button!

Q: How are blank lines handled?​

Blank lines are treated as regular lines and their position changes during line order reversal.

Q: Can this tool be used for encryption?​

Simple obfuscation is possible, but it's not suitable for security encryption. Anyone can easily decrypt it.

Practical Tips​

1. Creating Palindromes​

Enter a word, reverse the entire text, then combine the original and reversed to create a palindrome:

Original: ABC
Reversed: CBA
Palindrome: ABCCBA

2. Mirror Text​

After reversing entire text, you can read the original text when viewed in a mirror.

3. Log Analysis​

Use line order reversal to see the latest logs first.

4. Language Learning​

Practice spelling with word-by-word reversal.

Browser Compatibility​

This tool works normally in the following browsers:

  • Chrome (all versions)
  • Firefox (all versions)
  • Safari (all versions)
  • Edge (all versions)
  • Opera (all versions)

Fun Facts​

Palindrome​

Words or sentences that are the same when reversed:

racecar → racecar
level → level
A man a plan a canal Panama

Ambigram​

Some words have different meanings when reversed:

SWIMS → SWIMS (when flipped upside down)

Retrograde Music​

Reversal techniques are also used in music. Playing note sequences backward is called "retrograde."
