Free Random File Type Generator

This tool produces results like multipart, video, application, and many others - covering a wide variety of content categories commonly used in HTTP headers and media classification.

You can generate up to 1000 file types at a time and download them as CSV, Excel, or HTML files, or simply copy the results to your clipboard for seamless integration.

Each file type is randomly selected from a curated list that mimics actual file type categories, making it ideal for testing APIs, forms, upload features, or metadata fields.

Whether you're building a file browser, validating content-type logic, or populating sandbox data, these file types help you add credible realism to your prototypes or backend processes.

The tool is 100% free, requires no sign-up, and delivers quick, ready-to-use output to support your dev, QA, or demo needs.
