8 transformation modes — reverse characters, words, lines, flip upside down, mirror text and more. Live preview, 100% private, runs in your browser.
A reference showing exactly what each transformation does to the input "Hello World" .
| # | Mode | Input | Output | What changes |
|---|---|---|---|---|
| 1 | 🔄 Reverse Text | Hello World | dlroW olleH | Every character reversed across the entire string |
| 2 | 🔁 Reverse Each Word | Hello World | olleH dlroW | Characters within each word reversed; word positions stay |
| 3 | ↔️ Reverse Word Order | Hello World | World Hello | Words reordered from last to first; characters stay |
| 4 | ⬆️ Reverse Line Order | Line 1↵Line 2 | Line 2↵Line 1 | Lines reordered from bottom to top; each line unchanged |
| 5 | ↩️ Reverse Each Line | Hello↵World | olleH↵dlroW | Each line reversed independently; line order stays |
| 6 | 🙃 Flip Upside Down | Hello | oןןǝH | Unicode IPA characters + reversed for 180° rotation effect |
| 7 | 🪞 Mirror Text | Hello | oʇʇǝH | Unicode mirror look-alikes + reversed for mirror effect |
| 8 | 📝 Reverse Sentences | Hi. Bye. | Bye. Hi. | Sentences reordered; individual sentences unchanged |
Upside-down and mirror text work on Instagram, Twitter/X, TikTok, and Discord using standard Unicode — no special app needed. Great for making bios and usernames stand out.
Reverse the character order or word order to create simple ciphers for escape rooms, scavenger hunts, or fun puzzles. The recipient can paste the result back in to decode.
Verify your string reversal algorithm output. Reversing strings is a classic coding interview question in Python, JavaScript, Java, and C++. Use this tool to check expected outputs instantly.
The built-in palindrome checker shows instantly whether your text reads the same forwards and backwards — useful for writing palindromic poetry, wordplay, and linguistics exercises.
Use "Reverse Line Order" to flip a log file so the most recent entries appear at the top — useful when debugging and the newest events are appended to the bottom.
Reverse sentence order to restructure paragraphs, use mirrored text as decorative headings, or flip a poem upside down for visual art and typographic design projects.
# Method 1: Slicing (most Pythonic) s = "Hello World" reversed_s = s[::-1] # Output: "dlroW olleH"# Method 2: reversed() iterator reversed_s = ''.join(reversed(s)) # Reverse word order words = s.split() words.reverse() result = ' '.join(words) # Output: "World Hello"
// Method 1: split/reverse/joinconst s = "Hello World"; const reversed = s.split('').reverse().join(''); // Output: "dlroW olleH"// Unicode-safe (handles emoji)const safe = Array.from(s).reverse().join(''); // Reverse word orderconst wordRev = s.split(' ').reverse().join(' '); // Output: "World Hello"
// Using StringBuilder.reverse() String s = "Hello World"; String reversed = newStringBuilder(s) .reverse() .toString(); // Output: "dlroW olleH"// Reverse word order String[] words = s.split(" "); Collections.reverse(Arrays.asList(words)); String result = String.join(" ", words); // Output: "World Hello"

reversed_s = my_string[::-1]
. The
[::-1]
slice reads the string with a step of -1, effectively reversing it. Other approaches include
''.join(reversed(my_string))
using the built-in
reversed()
function, or a manual loop. For reversing word order:
' '.join(my_string.split()[::-1])
.
const reversed = str.split('').reverse().join('');
— split into an array of characters, reverse the array, join back. For Unicode safety with emoji and multi-codepoint characters, use
Array.from(str).reverse().join('')
which correctly handles surrogate pairs. To reverse word order:
str.split(' ').reverse().join(' ')
.
=TEXTJOIN("",TRUE,MID(A1,LEN(A1)+1-ROW(INDIRECT("1:"&LEN(A1))),1))
. In VBA you can define a custom function:
Function ReverseText(s As String): ReverseText = StrReverse(s): End Function
. For a quick no-formula approach, paste your text into this online tool and copy the reversed result back into Excel.
