About PDF Hub
PDF Hub is a collection of 21 free PDF tools — merge, split, compress, convert, protect, and more — built around one rule: your documents belong on your device. Every tool processes files locally in your browser, so your files never leave your device — nothing is stored, and there is nothing to trust us with.
Local by design
Every tool runs as JavaScript inside your browser tab. Files are read with the File API, processed in memory with libraries like pdf-lib and PDF.js, and written back to your downloads folder. There is no upload endpoint because there is no backend that handles documents.
Free without limits
No accounts, no credit card, no daily quota, and no watermarks on output. Because processing happens on your device, serving a tool to you costs us nothing per file — so every tool stays free and unlimited.
Open to verification
Skeptical of privacy claims? Good. Open your browser's developer tools, watch the network tab while you process a file, and see for yourself that no document data leaves the page. The code in your browser is the product.
Read the fine print yourself
The privacy policy spells out exactly what happens to your files — and what does not. Read the privacy policy, or jump straight to all 21 tools.
