BookmarkedTools is a developer-first suite of 100% browser-native online utilities. We engineered every single tool to run entirely inside your browser's local sandbox — eliminating cloud server uploads, security risks, subscription paywalls, and artificial file limits.
Most online tools on the internet today operate on an outdated client-to-server model. When you compress a photo, validate a JSON payload, or sample a color, traditional websites upload your files to remote cloud servers.
Modern personal computers and smartphones possess immense compute capability. Modern browsers are equipped with high-performance V8 JavaScript engines, WebAssembly runtimes, and hardware-accelerated Canvas APIs.
