FAQ
What is character frequency analysis used for?
Character frequency analysis is used in cryptography (frequency attacks), text classification, data compression algorithm tuning, encoding issue debugging, and more. In English text, the letter "E" appears most frequently (about 12.7%), so analyzing character frequency can help with simple substitution cipher cracking.
Which character types are supported?
All Unicode characters are supported, including letters, digits, punctuation, Chinese characters, Japanese kana, special symbols, and emoji. Each character shows its Unicode code point and type category.
Will my data be uploaded to a server?
No. All analysis is completed locally in your browser. Your text data is never uploaded to any server.
