Fixed Sample Files
Download deterministic sample files of fixed sizes (1KB to 1GB).
How does this tool work?
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.
