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.
Where are my data processed?
Only in your browser. Your data is not sent to any server.
The tool calculates and converts with JavaScript right on your device. Input and files are not sent to us or anyone else. You can check this yourself: load the page, disconnect from the internet, and the tool keeps working in the open tab.
