FAQs – PDF HUB

Answers to all common questions about privacy, speed, tools, mobile support, and more.

General Questions

Is PDF HUB really free? Yes, 100% free. No hidden fees, no “pro” upgrade popups, no watermarks — ever.

Do I need to create an account? No. Just open the site and start using any tool instantly.

Are my files private and safe? Yes — completely. Your PDF never leaves your device. All processing happens in your browser only. We literally cannot see your files.

Why is PDF HUB so much faster than other sites? Because there’s no upload/download wait time. Everything happens instantly on your side.

Will you ever add watermarks or limits? Never. That’s our promise.

Security & Privacy

Do you store my files? No. Since files are processed in your browser, nothing ever reaches our server.

Do you use cookies or trackers? No cookies, no analytics that track you, no ads, no third-party scripts.

Can I use PDF HUB for sensitive documents (legal, medical, financial)? Yes — it’s actually one of the safest options because your files never get uploaded anywhere.

What happens when I close the tab? All files and data are automatically wiped from memory. Nothing remains.

Tools & Features

Which tools are available? Merge, Split, Compress, Convert (to/from Word, Excel, JPG, PNG), Rotate, Unlock, Add Page Numbers, Watermark, Edit Text, Sign PDF, and more coming every month.

Can I use PDF HUB on mobile? Yes — fully works on Android, iPhone, iPad, and tablets.

Do the tools work offline? Not yet (needs internet to load the site), but we’re working on a PWA version that will work offline.

Why do some tools sometimes not work on very large files? Very large or complex PDFs (100MB+) can slow down or crash the browser. This is a browser limitation, not ours. Try splitting large files first.
