About NoUpload

NoUpload is a collection of file and developer tools that run entirely inside your web browser. There is no upload step, because there is no server doing the work. The processing happens on your own device, using WebAssembly and modern browser APIs.

Most online converters work by uploading your file to someone else's computer, processing it there, and sending the result back. That means handing your documents, photos and videos to a third party you have no reason to trust. In March 2025 the FBI warned that free online file converters had become a common vector for malware and data theft.

We built the alternative. Your files are never transmitted anywhere, so there is nothing to leak, nothing to retain, and nothing to subpoena.

Don't take our word for it. Verify it yourself: load a tool, turn off your Wi-Fi or switch to airplane mode, and use it. It still works, because everything it needs is already running on your machine.
