About JupiterPdf
JupiterPdf is a browser based PDF toolkit built for speed, privacy, and simplicity. With 97+ powerful tools, you can edit, convert, organize, and secure PDF files without ever uploading them to a server.
Why We Built This
Most PDF tools require users to upload sensitive documents or place essential features behind expensive paywalls. We believed there was a better approach.
This toolkit was created to give everyone access to professional PDF tools while keeping full ownership of their data. All processing happens directly inside the browser, so files stay on the user device at all times.
Whether working on assignments, business documents, or everyday files, users can complete tasks quickly and securely.
What We Stand For
Your Data, Your Control
PDF files are processed locally on your device. There are no uploads, no tracking, and no data collection.
Built for Speed
Instant results powered by modern web technologies without waiting for servers or downloads.
Works Everywhere
Works on any device and any modern browser, with support for 9 languages.
Free Without Limits
No accounts, no subscriptions, and no hidden restrictions. Just open the app and start using it.
Transparent by Design
Every feature is built with clarity and user trust in mind, ensuring predictable behavior and strong privacy protections.
Built With Users
Feedback from real users drives continuous improvement and feature refinement.
How It Works
This product is engineered using modern browser technologies to deliver performance and security:
- Next.js for fast, scalable, and search friendly web pages
- WebAssembly for high speed PDF processing inside the browser
- Web Workers for smooth background processing without interface freezes
- pdf-lib and PDF.js for accurate and reliable PDF manipulation
- IndexedDB for secure local file handling
This setup enables desktop level PDF functionality entirely in the browser without relying on servers or compromising privacy.
