Welcome to SuperToolsOnline. We build specialized, high-performance web utilities for a generation that values data sovereignty.
The internet is cluttered with online converters that demand your data in exchange for service. We believe the browser is powerful enough to handle these tasks locally.
Client-Side Only
Your files never touch our servers. Processing happens entirely within your browser's secure context.
Hardware Speed
By utilizing WebAssembly and native APIs, we deliver desktop-grade performance without upload latency.
100% Open Access
No registrations, no subscriptions, and no usage limits. Essential tools should be free for everyone.
Secure & Clean
No bloated software to install. Just clean, optimized code that runs on any modern device.
Our Philosophy
Our mission is simple: to make file conversion, text analysis, and productivity calculation as fast and as private as using a local app, but with the convenience of a web page.
