Text Reverser

It splits the input by Unicode code point before reversing, so a single emoji stays whole rather than turning into two garbled surrogate halves. Sequences built from several code points, like family emoji or flags, can still come apart, since those are genuinely multiple characters joined together.

Yes, there's no signup, no quota, and no upload. The reversal is a few lines of JavaScript running in your own browser tab, so it even works offline once the page has loaded.

More than you'd guess. Teachers use it for mirror writing exercises, puzzle makers hide answers with it, developers feed reversed strings into forms to probe rendering and validation, and plenty of people just want a strange looking username.

No, punctuation travels with the characters around it. Reverse Hello, world! and you get !dlrow ,olleH, with the exclamation mark now leading. If you want words moved but left readable, that's a word order flip, not a character reversal.

Reversed text makes a cheap adversarial input. It preserves length and character set while destroying meaning, which is handy for checking truncation, right to left rendering quirks, and whether a parser chokes on unexpected orderings.

Completely. Running the reversed string through the tool a second time restores your original text exactly, code point for code point. That round trip is also a quick way to verify nothing was mangled.

It can reverse tens of thousands of characters without slowing down, since the work is a single in-memory pass. Just note that reversed paragraphs are nearly unreadable, which is sort of the point.
