Reverse a string by character, word or line.
Updated
Quick start
Pick a granularity, paste your text, copy the reversed output.
Characters for letter-by-letter reversal (emoji-safe), Words to flip word order, Lines or Sentences to reorder blocks.
Drop the input into the left pane. Multi-line and Unicode-rich text are both supported.
Hit Copy or press ⌘/Ctrl+Enter. Punctuation, whitespace runs and line endings are preserved.
In-depth guide
Reverse any text — at character, word, line or sentence granularity — without breaking emoji, combining marks, or your line endings. Useful for crosswords and word puzzles, generating mirror strings for tests, flipping list order, or just curiosity.
hello → olleh; café → éfac; 👨👩👧 hi → ih 👨👩👧 (emoji intact).The quick brown fox → fox brown quick The. Whitespace runs are preserved.., !, ? and reverses sentence order, leaving the terminators attached to the right sentence.If your browser doesn't support Intl.Segmenter (very old mobile browsers), we fall back to code-point reversal — better than UTF-16 but still imperfect for joined emoji.
JavaScript strings are UTF-16 code units. A family emoji like 👨👩👧 is actually 11 code units glued together with zero-width joiners. The classic str.split('').reverse().join('') trick splits between every code unit and produces gibberish — combining marks attach to the wrong base character, surrogate pairs become unmatched halves.
This tool uses Intl.Segmenter with granularity: 'grapheme', which implements Unicode Standard Annex #29. The result is what users perceive as "characters" — and reversing those, instead of code units, gives correct output for every script.
When to reach for it. Use it to flip a string, reverse word order, or create mirror-style text for puzzles and quick checks.
When something else is better. It’s a transformation toy, not a cipher — reversed text offers no real security.
The pitfall to watch. Emoji and accented characters are multi-code-unit; a naive reverse can split them, so combined glyphs may break.
Everything runs on your device. The values you enter are processed locally in this browser tab — EpitomeTool does not send your input to a server, store it, or log it. That means you can use the tool offline once the page has loaded, and refreshing the tab wipes the slate.
No. Reversal runs entirely in your browser using standard JavaScript and the Intl.Segmenter API. DevTools → Network shows zero requests during use.
Character mode segments the input into grapheme clusters using Intl.Segmenter, so multi-codepoint emoji like 👨👩👧 stay as one unit. Naive reversal with `.split('').reverse()` would tear them apart into invalid sequences.
Yes. We split on whitespace runs, reverse only the word chunks, and reassemble — so double spaces, tabs and trailing punctuation end up exactly where they were, just attached to different words.
We detect which line ending dominates and use the same one when rejoining. Files copied from Windows stay CRLF; Unix files stay LF — no silent line-ending changes.
Line reversal flips literal newline-separated lines; sentence reversal splits on `.`, `!` and `?` regardless of line breaks. Pick line for poetry / lists, sentence for prose.
Yes, but reversing characters and using a mirroring font are different things. This tool reverses logical order; for visually-mirrored text you'll still need a right-to-left script or a glyph-flipping font.
