Free Text Reverser — Flip Characters, Words & Lines

Reverse text in three different ways: flip every character ("hello" → "olleh"), reverse the order of words ("hello world" → "world hello"), or reverse the order of lines in a list. Useful for puzzles, palindrome checks, creative writing and developer testing.

Features

Reverse characters, words, or whole lines
Live preview as you type
Unicode-safe — handles emojis and accents
Copy result in one click

How to use

Step 1. Paste your text in the input area.
Step 2. Pick a reverse mode: characters, words or lines.
Step 3. Copy the reversed output.

Real use case: verifying that a name field survives round-tripping

A QA engineer is testing a signup form that started mangling names containing emoji and accented characters after a database migration. Reversing a string is a quick way to prove whether the pipeline treats text as real Unicode characters or as raw bytes.

The engineer reverses "José 👨‍👩‍👧" in the tool, pastes the result into the form, submits, and reverses the stored value back. If it does not match the original exactly, the stack is splitting multi-byte sequences somewhere — a concrete, reproducible bug report instead of "names look weird sometimes".

How Text Reverser works

Character mode splits the string with the Unicode-aware iterator (spread over the string / Intl.Segmenter semantics) rather than by UTF-16 code units. That matters: a naive split('').reverse() breaks surrogate pairs and turns an emoji into two invalid characters.

Word mode splits on whitespace runs, reverses the array and re-joins with single spaces. Line mode splits on newline boundaries and reverses the order while preserving each line's internal content — useful for flipping chronological logs.

All three modes are pure string operations executed in your browser as you type, so there is no upload, no limit and no latency.

Text Reverser vs similar tools

Other ways to reverse text, and their limits:

Tool	How it works	Trade-off
One-line JavaScript in the console	str.split('').reverse().join('')	Corrupts emoji and combining accents because it works on UTF-16 units.
Command line (rev)	Reverses each line's characters in a terminal.	Requires a shell, and locale handling of multibyte input varies by system.
ToolZone Text Reverser	Unicode-safe character, word and line reversal with live preview.	Manual paste-in workflow, not scriptable in a build pipeline.

Frequently Asked Questions

Does it work with emojis?

Yes. We split text using Unicode code points so multi-byte emojis stay intact when reversed.

Can I check if a word is a palindrome?

Reverse the word in 'characters' mode — if the output matches the input (ignoring case), it's a palindrome.
