A random file generator creates downloadable files containing randomly generated data. Developers, software testers, and students can use these files to test file uploads, downloads, storage systems, and application performance without creating sample documents manually.
With Toolsten's Random File Generator, you can choose the file format, specify the size of each file, and generate multiple files in a single batch. For example, generate ten 500 KB text files or five binary files for testing upload restrictions.
Download individual files when you need specific test samples, or use the ZIP download option to collect all generated files into one archive. Files are generated directly in your browser, with no account or server upload required.
