Reverse Text
Reverse text by characters, words, or lines with multiple transformation modes.
About This Tool
The Reverse Text tool is a free browser-based utility that lets you reverse text in multiple ways: by characters, by words, by lines, by characters within each word, or by flipping the entire text upside down using Unicode look-alike characters.
Text reversal is a fundamental string operation used across many domains. Developers use it for algorithm practice, palindrome detection, and string manipulation tasks. Content creators use upside-down and mirrored text for creative social media posts, unique usernames, and eye-catching headlines. System administrators reverse log file lines to view the most recent entries first.
The Characters mode reverses the entire input character by character, turning "Hello World" into "dlroW olleH". The Words mode reverses the order of words in each line while keeping individual words intact. The Lines mode flips the order of lines, useful for reversing chronological logs. The Each Word mode reverses the characters within each word but keeps words in their original order. The Flip Upside Down mode uses a Unicode character mapping table to produce text that appears rotated 180 degrees.
Every operation runs entirely in your browser using pure JavaScript string manipulation. No data is transmitted to any server, no cookies are set, and no input is logged. This makes the tool safe for any content you want to transform. You can also use our Text Case Converter for changing letter casing, our ROT13 / Caesar Cipher for letter-shift encoding, or our String Escape/Unescape for format-specific escaping.
Whether you are solving coding challenges, creating fun social media content, or processing text data, this tool provides instant results with zero setup required.
How to Use
- Select a reversal mode using the tabs at the top: Characters, Words, Lines, Each Word, or Flip Upside Down.
- Paste or type your text into the Input textarea on the left.
- The reversed result appears instantly in the read-only Output panel on the right.
- Read the mode description below the tabs to understand exactly what the selected mode does.
- Click Copy to copy the output to your clipboard, or use Ctrl+Shift+C.
- Use the Swap button to move the output back into the input for further transformations.
- Click Clear to reset both fields and start over.

FAQ
Is my data safe when using this tool?
Yes. All text reversal is performed entirely in your browser using client-side JavaScript. No data is sent to any server, and nothing is stored or logged. It is safe to use with any text content.
What is the difference between the reversal modes?
Characters mode reverses the entire string character by character. Words mode reverses the order of words in each line. Lines mode reverses the order of lines. Each Word mode reverses characters within each word while keeping word order. Flip Upside Down uses Unicode characters to make text appear rotated 180 degrees.
Does the Flip Upside Down mode work with all characters?
The Flip Upside Down mode maps common Latin letters, digits, and punctuation to their Unicode look-alikes. Characters without a known upside-down equivalent are left unchanged. The result is approximate and works best with basic ASCII text.
Can I use this tool to detect palindromes?
Yes. Enter your text in Characters mode and compare the output with the original input. If they match (ignoring spaces and case), the text is a palindrome. For example, 'racecar' reversed is still 'racecar'.
Does this tool handle Unicode and emoji correctly?
Yes. The tool uses JavaScript's spread operator to split strings into Unicode code points, which correctly handles multi-byte characters, emoji, and characters outside the Basic Multilingual Plane.
Is there a character limit?
There is no hard character limit. The tool processes text entirely in your browser, so performance depends on your device. Very large inputs (over 1 MB) may cause a brief delay but will still work correctly.
