Why this tool is useful
Use character shuffling to create puzzle material, randomized letter exercises or test data where the original character inventory must remain unchanged.

Unicode Letter Shuffler
Shuffle Unicode characters with cryptographic browser randomness and a transparent two-million-character safety limit.
Ready. Your working data stays in this browser.
How it works
A rejection-sampled crypto.getRandomValues index drives an unbiased Fisher–Yates shuffle over Unicode code points. No seed or source text leaves the tab.
Practical example
Shuffle ABCD repeatedly to get changing orders such as CADB while every result still contains A, B, C and D exactly once.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
