Why do emoji sometimes look broken when I reverse characters?

Some emoji are made of multiple code points (for example, a family emoji built from joined individual emoji). Reversing the code units can put combining marks on the wrong base, which may render oddly. Word or line reversal does not have this problem.

Does it preserve my line breaks?

Character reversal keeps every newline in place, just reversed. Word reversal preserves line structure and reverses words within each line. Line reversal reorders whole lines.

Is my text uploaded anywhere?

No. Reversal runs in your browser with built-in string operations. Your text never leaves the tab.

Can I undo a reversal?

Yes — reversing again restores the original. Click Reverse twice with the same mode selected.

Reverse Text

Reverse text in three ways: mirror every character, swap word order within each line, or flip the order of the lines themselves. Handy for puzzles, right-to-left language experiments, formatting tricks and testing edge cases.

How to use

1

Drop a sentence, paragraph or list into the input box.
2
Choose a mode
Reverse characters to mirror every glyph, reverse words to swap word order within each line, or reverse lines to flip the order of whole lines.
3
Reverse
Click Reverse. The result appears in the output box and stays until you reverse again or reset.
4
Copy or save
Use Copy to put the result on your clipboard, or Save to download reversed.txt.

Common use cases

Create a palindrome-style puzzle or social media post.
Reverse the order of a numbered list so the latest item appears first.
Inspect how a string reads right-to-left for Arabic or Hebrew testing.
Mirror a paragraph for fun in messages or screenshots.

Limitations

Character reversal uses Array.from so surrogate pairs (emoji) stay together, but combining marks may end up on the wrong base character.
Word reversal joins words with a single space; original spacing between words is not preserved.
Line reversal treats \\r\\n and \\n as line separators and emits \\n in the output.
