Reverse Text
TextEverything runs locally in your browser — nothing is uploaded
Reversing text is ambiguous, and the four readings give entirely different results: `abc` becomes `cba` (within each line), the first line becomes the last (line order), the whole text is turned around including its line breaks (whole text), or `one two` becomes `two one` (word order). So this tool offers four separate options rather than one Reverse button — guessing wrong costs you another paste. It reverses by grapheme cluster, not by code unit. `"👍🏽".length` is 4: an emoji with a skin-tone modifier takes four UTF-16 code units. Reversing those units yields two lone surrogates and the screen shows `��`. Reversing by code point fixes surrogate pairs but still splits ZWJ sequences such as `👨👩👧` and accented letters written as base plus combining mark. This tool therefore cuts on the browser’s native grapheme boundaries — what you would call one character. Word order leaves your layout alone. Leading and trailing whitespace and the gaps between words all stay where they are; only the words move. Reversing everything would turn ` foo bar` into `bar foo `, with the indent stranded at the end.
Features
- Four independent modes: within each line, whole text, line order and word order
- Grapheme-aware, so emoji, skin-tone modifiers, ZWJ sequences and combining marks never split in half
- Line-structure-preserving modes keep the number of lines unchanged
- Word order keeps leading and trailing whitespace and the gaps between words
- Line order is a pure reordering — nothing inside a line moves
- Handles CRLF, CR and LF, and always writes LF back
- Blank lines take part like any other (line order turns them around too)
- Everything runs locally in your browser; nothing is uploaded
How to use

FAQ
- What is the difference between “whole text” and “line order”?
- Line order only moves lines around; nothing inside a line changes: `abc / def` becomes `def / abc`. Whole text treats the entire thing as one sequence including the line breaks: `abc\ndef` becomes `fed\ncba`. The line count is unchanged either way, but each line now holds content from what used to be a different line, and a trailing newline flips to a leading one. It is the literal “rotate the paper 180°” reading, which is exactly why it is its own option.
- Why is my indentation still at the start after reversing word order?
- Because what moves is the words, not the characters. The line is split into an alternating sequence of words and gaps; the gaps stay in their slots and only the words are reordered. So ` foo bar ` becomes ` bar foo ` with both the two leading spaces and the trailing spaces intact. Reversing the gaps as well would strand the indent at the end, which counts as quietly reformatting your text.
- Will emoji get mangled?
- No. The text is cut on the browser’s own grapheme boundaries (the grapheme granularity of `Intl.Segmenter`), which follow what a reader would call one character rather than code units or code points. A skin-tone emoji like `👍🏽`, a ZWJ family sequence, and a letter written as base plus combining mark all survive as single units.
