About Internet Speed Test
Measure your download and upload speed, ping, and jitter in about twenty seconds. The test only sends and receives throwaway test data — no files, no account, no personal details. This focused Internet Speed Test page is designed for home and office users checking whether their Wi-Fi or broadband delivers the speed they pay for. It opens directly to the working tool, rather than hiding the function inside a general converter or account dashboard.
The input is parsed by JavaScript already loaded in the page, transformed in memory, and returned through a local browser download or copy action. Your filename and file contents stay on the device. There is no upload queue, temporary cloud copy, account record, or server-side conversion job to delete later. That makes the tool practical for personal records, work material, and drafts that should not be handed to an unknown processing service.
The important limitation is straightforward: Measured against Cloudflare's public speed endpoint. Browser tests can read slightly lower than dedicated apps on very fast connections. Knowing that boundary helps you choose the right source file and check the result before relying on it. Processing speed and maximum size depend on your browser and available device memory, which is the honest trade-off for doing the work locally.
FileForge charges nothing for this tool and does not add a watermark. Once the page and its processing engine have loaded, the operation can continue without sending the file over the network. Use the numbered steps below, download the result, and review it before replacing an original file.
