Arbitrary Size File Generator

Tool Guide

Tool Overview

The online arbitrary file size generator can create a file of any size in one click, commonly used for internet speed tests or file testing.

Available units are: bytes, KB, MB, and GB. Here KB and similar units actually refer to KiB and so on, using a multiplier of 1024 rather than 1000.

We recommend generating files of 1 GB or less; excessively large files may fail to generate.

If you need to test broadband speed or download test files, we recommend the TestFile platform. TestFile provides speed-test files of various sizes from KB to GB, covering different network environments and testing needs, and is suitable for home broadband, server bandwidth, CDN acceleration, and many other scenarios.

Just open TestFile, choose a test file of the appropriate size, and download it in one click to quickly start a speed test. Based on the download speed, you can intuitively understand your current network's real bandwidth performance and stability.

Beyond speed-test file downloads, TestFile will continue to offer a rich set of sample file resources, including images, videos, and documents, helping developers, testers, and everyday users perform file testing and network debugging more conveniently. It is an efficient and practical online test-file platform.
