What File Byte Frequency Analyzer does
Count occurrences and percentages for all 256 possible byte values in a local file without modifying it.
Input and output contract
One file up to 16 MiB is read locally; the report lists non-zero byte frequencies for convenient inspection. A copyable CSV-style frequency report.
Safe workflow
Choose a file and analyze its byte distribution before deeper format investigation. SaveEditor processes this operation locally in the browser and does not infer a game format from the input.
Important limitations
Byte frequency alone cannot prove encryption, compression, randomness, or corruption. Use the existing Entropy Analyzer when you need entropy measurements rather than raw frequency counts.
