Our Mission
Every day, millions of people need to convert, edit, or transform PDF files. Most existing tools either cost money, require registration, or - worst of all - upload your sensitive documents to remote servers.
PDFBase was created to solve this problem. We built a complete suite of PDF tools that process everything directly in your browser using WebAssembly and JavaScript. Your files never leave your device.
Whether you're converting a HEIC photo to PDF, merging multiple documents, or extracting text from a PDF, you can trust that your data stays private. No uploads, no accounts, no tracking - just tools that work.
Our Values
Every decision we make is guided by these core principles
Privacy First
Your files never leave your device. All processing happens directly in your browser using client-side JavaScript.
Fast & Free
No signup required. No payment needed. Just open a tool and start converting. Works offline too.
Open Technology
Built with modern web standards and open source libraries like pdf-lib and PDF.js.
Accessible Anywhere
Works on any device with a modern browser. Desktop, tablet, or mobile - your choice.
How It Works
You select a file
When you choose a file, it's loaded directly into your browser's memory. The file never leaves your device.
Processing happens locally
Using JavaScript libraries running in your browser, we convert, edit, or transform your file. No server communication required.
You download the result
The processed file is generated in your browser and downloaded directly to your device. We never see or store your files.
Privacy Guarantee
We can confidently say your files are 100% private because they never leave your device. We don't have servers to store files on, we don't have databases to log your activity, and we don't track what you convert.
