About this tool
Count letters or all non-whitespace symbols and rank them from most to least frequent. Every row includes the raw count and percentage share.
Frequency analysis is useful for exploring language and solving simple substitution ciphers. Longer samples normally give more representative rankings.

Good to know
Questions people actually ask
- Can frequency analysis break every cipher?
- No. It is useful against simple substitutions with enough text, but not against modern encryption.
- Why do short texts give unusual rankings?
- Language frequencies are statistical averages. Longer samples tend to produce more representative results.
