Text Reverser - Reverse Characters, Words & Lines Online
100% LocalFree online text reverser supporting character, word, and line modes with correct CJK and Emoji handling. All processing runs locally in your browser.
TL;DR: Free online text reverser with three modes: reverse by characters, words, or lines. Correctly handles multi-byte characters including CJK and Emoji. Real-time preview, one-click copy, all processed locally with no uploads.

Usage Guide
Reverse characters, reverse words, reverse lines — three reversal granularities for testing, puzzles and data munging. This tool handles multi-byte characters like CJK and emoji correctly instead of splitting them into garbage, all local.
1. How to use
- Paste the text you want reversed.
- Pick a mode: character reversal (Hello → olleH), word reversal (Hello World → World Hello), or line reversal (last line becomes first).
- Copy the output.
2. When each mode helps
- Character reversal suits palindrome checks, encoding experiments and reverse-lookups — but a reversed shuffle is never encryption.
- Word reversal helps reorder inverted-phrase data or generate repetitive-style copy.
- Line reversal reorders log timelines, chat history or CSV row order.
- Make sure the tool reverses by Unicode code point, not by byte — emoji will shatter into mojibake otherwise.
3. What else matters after reversing
Reversal is a pure text operation and does not change encoding — but "reverse by code point" and "reverse by perceived character" diverge on combining characters: é (e + combining accent) reversed by code point becomes a strange accent-first string. Code-point reversal is fine for most use cases; run NFC normalization first if humans will read the output. And if the reversed text feeds back into a program, verify the target system Unicode support level before shipping.
FAQ
Completely free, no registration required. Paste your text in the browser to reverse it — all operations run locally with no usage limits.
Three modes are supported: reverse by characters (full reversal), reverse by words (preserving letters within each word), or reverse by lines (line order flipped). Switch modes freely.
No. All reversal operations run locally in your browser. Your text is never sent to any server, ensuring complete privacy.
Yes. The tool uses a Unicode-safe reversal algorithm that correctly handles Chinese, Emoji, and other multi-byte characters without garbling or splitting surrogate pairs.
