About Super Utility Hub

Super Utility Hub is a free suite of online PDF tools built around one simple idea: your documents belong to you, and nobody needs to see them. Every tool — from merging PDFs to adding passwords — runs entirely inside your browser using JavaScript. Files are never uploaded, never stored, and never shared with anyone.

We built this website because the most popular PDF services take your documents to their servers, impose file size limits, and charge for features that should be free. Our tools have no limits, no accounts, and no watermarks.

The service is free for everyone and supported by advertising, which keeps the lights on without putting your files at risk.

Our principles

Privacy first — all processing happens on your device.
Free forever — no paywalls, no trials, no hidden fees.
No limits — use the tools as often as you like with files of any size.
Simplicity — open a tool, drop a file, download the result.
