The speed advantage of utool comes from eliminating the upload-process-download cycle entirely. When you click the action button, processing starts in the same millisecond. There's no HTTP request leaving your browser, no queuing on a remote server, no download of the result from across the internet.
utool's WebAssembly engine runs compiled binary code in your browser at near-native CPU speeds. For a typical file operation, this means results in 1–3 seconds, regardless of your internet speed — which is entirely irrelevant once the page is loaded.

At no point during the process is any data transmitted over the network. You can verify this yourself by opening your browser's Network Inspector (F12 → Network) and observing that no file upload requests are made.
