Character Shuffler
Shuffle characters in any text. Choose to randomize letters within each word, across the entire string, or per sentence. Useful for word puzzles, anagram practice, password noise, and quick-scramble obfuscation.
How to use the character shuffler
1. Paste your text
Drop a word, phrase, sentence, or paragraph into the input box. The shuffler picks a random ordering on every keystroke. Click "Shuffle again" for a new permutation of the same input.
2. Pick a shuffle mode
Three modes available. "Within each word" keeps word boundaries (great for anagram practice and word puzzles). "Entire string" shuffles all characters globally - words break apart. "Per sentence" shuffles letters within each sentence; sentence-ending punctuation stays in place.
3. Copy out
The Copy button puts the shuffled string on your clipboard. Paste it into a puzzle clue, a meme, an obfuscation challenge, or wherever you need randomized characters.
When you need to shuffle characters
Anagram practice and word puzzles
Anagram solvers thrive on shuffled inputs. Take a target word ("listen") and shuffle within-word mode to get test inputs ("sileln", "iesltn", etc.) for an anagram-solving drill.
Scrabble and word-game tile order
If you have 7 Scrabble tiles ("R-A-I-N-B-O-W"), shuffling them randomizes the visual order to break psychological fixation. Sometimes a fresh order surfaces a word you missed.
Password and noise generation
Need a quick noisy string for a placeholder password, a test database, or a randomized variable? Paste a candidate string and shuffle whole-string mode. Result is unpredictable but contains the same character set as the input.
Captcha-style obfuscation
Need to hide an email or phrase from low-effort scrapers? Shuffle within-word: "myemail@example.com" becomes "miyaeml@xaepmle.com". A human can decode at a glance; a bot reading the rendered text will not match it to the original.
Children's word-puzzle worksheets
Teachers building unscramble worksheets need shuffled words. Paste the target word list, shuffle within-word, copy out. Print as a worksheet.
Stage names and creative writing
Anagram-derived names are a long tradition (Pamela becomes "A-Lamp" then "Almap"). Shuffle a base word, browse permutations until something euphonic appears.
How the shuffle works
The shuffler uses the Fisher-Yates algorithm: iterate the array of characters from the last index to the first, swap each element with a randomly chosen earlier element (or itself). The result is a uniformly random permutation of the input. JavaScript's `Math.random()` provides the randomness; it is good enough for puzzles and play but is NOT cryptographically secure (don't use this for password generation if security matters - use a real password manager).
Mode behaviors in detail
- Within each word: identifies word boundaries (any run of letters), shuffles the letters in each word independently, leaves whitespace and punctuation untouched. "The quick fox" → "Teh kiucq oxf".
- Entire string: shuffles every character (letters, spaces, punctuation, all). "The quick fox" → "qoiceh xufkT ". Word boundaries dissolve.
- Per sentence: splits on sentence-ending punctuation (. ! ?), shuffles characters within each sentence (letters AND spaces), leaves the sentence terminator in place. "The fox. The cat." → "ehoT fx. taTeh c." Each sentence is shuffled independently.
Shuffled text and reading comprehension
A 2003 internet meme claimed that words with their middle letters shuffled (first and last letter intact) are still readable. The Cambridge effect, supposedly. The original claim was overstated - comprehension drops noticeably as shuffling increases - but partial readability does hold for short common words. Our sibling tool text scrambler implements the Cambridge-effect variant (preserve first and last letter). This page shuffles everything inside the word, including the first and last letters. Result: less readable, more random, useful when you actually want obfuscation rather than just visual noise.

Frequently asked questions
How is this different from a text scrambler?
The text scrambler implements the Cambridge effect: it preserves the first and last letter of each word and only shuffles middle letters. This shuffler randomizes every character, including first and last letters. Use scrambler for readability-preserving obfuscation; use this shuffler for full randomization.
Is the shuffle truly random?
It uses Fisher-Yates with JavaScript's Math.random(), which produces uniformly distributed permutations. Math.random() is NOT cryptographically secure, so do not use this for password generation. For puzzles, anagrams, and play it is good enough.
What's the difference between 'within each word' and 'entire string'?
Within-word keeps word boundaries (spaces and punctuation in place; only letters inside each word are shuffled). Entire-string shuffles every character including spaces, so words break apart.
Can I shuffle a single word repeatedly to find anagrams?
Yes, with the 'Shuffle again' button. Each click re-shuffles. You will see different permutations of the same input. For exhaustive anagram solving, use a dedicated anagram-solver tool (word.tips/anagram-solver/ shows all valid English anagrams).
Will my text be sent to a server?
No. Shuffling runs entirely in your browser. Pasted text never leaves this tab.
Does the shuffler preserve punctuation?
Yes, in within-word and per-sentence modes. In entire-string mode, punctuation gets shuffled with everything else.
Can I use this to generate a strong password?
No. Math.random() is not cryptographically secure. Use a password manager (1Password, Bitwarden, your browser's built-in generator) for real passwords. The shuffler is for play, puzzles, and lightweight obfuscation.
Does it work with emoji and Unicode?
Yes for shuffling, but with caveats. Emoji that consist of multiple codepoints (skin-tone variants, zero-width joiners) may split into their components and produce weird intermediate sequences. ASCII and basic Latin text works perfectly. See also: text shuffler. See also: palindrome maker. See also: all utilities.
