The core principle: your browser does the work
Every tool on PDF Genius Pro runs entirely in your browser using JavaScript and standard browser APIs. When you use any tool, your browser downloads a small processing program, runs it locally using your device's CPU and memory, and saves the result directly to your downloads folder. At no point does your document travel to any external server.
This is fundamentally different from how most online PDF tools work. Services like Smallpdf, ILovePDF, and Adobe Acrobat Online require you to upload your document to their servers. Your file travels to their infrastructure, gets processed there, and is sent back as a download. During that process, those companies technically have access to your file. PDF Genius Pro does not.
Technologies used for local processing
PDF Genius Pro uses several established open-source browser libraries:
- PDF.js — Mozilla's PDF rendering library for reading PDFs in the browser
- pdf-lib — Creates and modifies PDFs entirely in the browser
- Tesseract.js — OCR engine compiled to run in the browser via WebAssembly
- Mammoth.js — Reads Word (.docx) format in the browser
- JSZip — Creates ZIP archives of multiple output files, entirely client-side
These use standard Web APIs built into every modern browser including Chrome, Firefox, Safari, and Edge. No browser extensions or plugins are required.
What data does leave your device?
- Your files do not leave your device — document content is never transmitted over the network.
- Anonymous analytics may be collected if you accept cookies (page views, tool usage counts — no document data).
- Contact form submissions are transmitted when you use the contact form. No document data is involved.
What happens when you close the tab?
When you close the browser tab, any temporary file data in your browser's memory is released. PDF Genius Pro does not use localStorage, IndexedDB, or service worker caches to store your files between sessions. Only your cookie consent preference persists.
Verifying this yourself
Open any tool page, press F12 to open DevTools, go to the Network tab, and process a document. You will see requests for JavaScript files and analytics scripts — but no requests containing your PDF data. The absence of any binary POST requests with your file content confirms that your document is not being transmitted.
GDPR and privacy regulations
Because we never receive your documents, we are not acting as a data processor for those files under GDPR. Our data processing is limited to analytics data (if you consent) and contact form data. For data subject rights requests, contact concerns@pdfgeniuspro.com.
