# RoundCut

> RoundCut is a privacy-first image-tools site. 21 live tools today (7 general tools + 12 convert format pairs + 2 family hubs) across 29 locales. Different tools have different architectures: some run entirely in your browser, some use a hybrid client-preview / server-encode model, some need cloud inference. Each tool's page describes its own architecture honestly.
