Your images never leave your device.
Every conversion on Filexum runs inside your browser using WebAssembly. There is no upload and no server that receives your files, so nothing about your images — not the pixels, the filename or a hash — is ever sent over the network. You can prove it: open your browser's Network tab and watch it stay silent, or turn off Wi-Fi and convert anyway.
