Reverse text at four granularities: characters ("hello" → "olleh"), words (per line, keeping whitespace), sentences (split on . ! ?), or lines (first ↔ last). Character mode uses grapheme-cluster reversal so emoji and Chinese / Arabic / Hindi stay intact.

What is Text Reverser?

A text reverser flips the order of units in a string. Choosing the right unit matters more than it sounds: naïvely reversing a JavaScript string as [...str].reverse().join("") will split composite emoji like 👨‍👩‍👧 into their component code points, producing garbled output. This tool uses Intl.Segmenter to reverse by grapheme cluster, so any user-visible character — including combining marks, ZWJ emoji sequences, flags, and skin-tone modifiers — is preserved. Word and sentence modes work on English-language conventions and preserve original whitespace and punctuation position so "Hello, world!" reverses cleanly into "world! Hello,".

How to reverse text online

1Paste your text into the input pane.
2Pick a reversal mode: Characters, Words, Sentences, or Lines.
3The output pane updates instantly. Use the Copy button to grab the result.
4Chain operations by using the reversed output as the input to another tool (e.g. Sort → Reverse for a Z→A sort).

Use Cases

Puzzles, brain-teasers, and social-media posts

Generate 'sdrawkcab written' text for jokes, cryptic-clue setups, or engagement bait.

Reverse a filename or ID batch

Use Line-reverse mode to flip a long list so the last entry appears first — no scripting needed.

Test edge cases in string-handling code

Reversed Unicode strings expose bugs where code accidentally uses .length on a JS string containing astral characters.

Quick obfuscation for demos

Character-reversed text is machine-recoverable but not human-readable at a glance — useful for hiding spoilers or answer keys.

Key Concepts

Grapheme cluster: The user-perceived unit of text. A single emoji like 👨‍👩‍👧 is one grapheme cluster but four code points and eleven UTF-16 code units.
Intl.Segmenter: The Unicode-aware string segmentation API standardized in ECMAScript. Provides grapheme / word / sentence boundaries that match user expectations.

Tips & Best Practices

▸Character reverse uses Intl.Segmenter — supported in Chrome/Edge 87+, Safari 14.1+, Firefox 125+. On very old browsers the tool falls back to code-point reversal.
▸Word mode preserves per-line word order — if you want to reverse across the entire input, first join lines with spaces.
▸For search-engine-friendly obfuscation, don't use reverse — it fools no one but hurts crawlers.
▸Combine with the Sort tool for Z→A: sort ascending, then Line-reverse — cleaner semantics than a native descending sort in some pipelines.

Frequently Asked Questions

Which reverse modes are supported?

Four modes: Characters (flip every character, emoji-safe using Intl.Segmenter), Words (reverse word order per line while keeping spacing), Sentences (reverse order of sentences split on . ! ?), and Lines (first line becomes the last).

Does character reverse work with emoji and Chinese?

Yes. It uses Intl.Segmenter for grapheme-cluster reversal, so composite emoji like "👨‍👩‍👧" and multi-byte characters (Chinese, Arabic, Hindi) stay intact instead of being broken apart.

Is the reversed text still readable by search engines?

No — reversing text produces machine-visible but human-unreadable output. Use it for jokes, puzzles, ROT-style obfuscation, or as an intermediate transform in a pipeline. Never for accessibility or SEO copy.

Is my text uploaded anywhere?

No. Reversal runs entirely in your browser — nothing is sent to a server.
