This solves a real anxiety I've had for years. Every time I needed to compress a PDF or strip image metadata, I'd hesitate before uploading to some random site — not knowing where my files actually went. Tax docs, contracts, medical records… you just don't know. KeptLocal flips the model entirely. WebAssembly in the browser means your files genuinely never leave your device. You can even open DevTools and verify zero network requests — that level of transparency is rare and refreshing. 27 tools, no account, no watermarks, works offline after load. This is the kind of product that should be the default. Congrats on the launch — bookmarked immediately.
