## How it works

Provides quick access to standardized sample files for testing purposes.

Choose from a list of predefined file sizes (from 1 KB up to 1 GB) or enter a custom size. Unlike random files, these files are deterministic: they are generated from a fixed, repeated data block, so a given size always produces the same content. A single click starts the download locally in your browser.

Fills byte arrays deterministically using repeating data patterns. Assembles sample files of exact target sizes in memory for instant downloads.
