About the String Reverser
This tool reverses a string character by character while keeping Unicode intact, so emoji, accented letters and combining marks are never split into meaningless fragments. Word and sentence reversal modes are available alongside it for flipping larger units.
Reversing a string is the classic programming exercise, and also the classic place naive code breaks. Reversing by code unit splits emoji and accented characters into meaningless halves, because a single visible character can occupy several units.
This handles the text as grapheme clusters — what a reader sees as one character stays one character. A string containing an emoji or a combining accent reverses cleanly rather than coming back as replacement squares.
Alongside character reversal, word and sentence modes flip larger units while leaving the smaller ones intact. Useful for palindrome work, puzzles, generating test strings, and checking how a system handles right-to-left or unusual input.

Frequently asked questions
Why do some tools break emoji when reversing?
They reverse by code unit rather than by visible character, which splits emoji and accented letters into fragments.
Does this handle accented characters?
Yes. Text is reversed by grapheme cluster, so accented letters and combining marks stay intact.
Can I reverse word order instead?
Yes. Word and sentence modes flip the larger units while leaving individual words readable.
Is there a length limit?
Nothing fixed. Very long strings are limited only by your device's memory.
Is my text uploaded?
No. Reversal happens entirely in your browser.
