Why I built a 100% client-side utility suite with WebAssembly (Zero server uploads)

Hey Product Hunt community!

I'm Noureddine, and tomorrow I'm launching KioTools (kiotools.com)!

Every time I needed a quick online utility converting files, optimizing images, or formatting data I hated having to upload my files to a random cloud server and wait in a queue.

So I built KioTools to run entirely inside the browser using WebAssembly. Nothing ever leaves your device, meaning instant processing and 100% privacy.
