Frequently Asked Questions
Everything you need to know about our privacy-first technology.
Are my PDF files uploaded to your servers?
Absolutely not. gKPDF is built entirely on client-side technology. When you use tools like Protect PDF or Split PDF, the modification happens directly in your browser's memory. Your data never touches our servers, ensuring 100% privacy.
Is gKPDF really 100% free for everyone?
Yes! There are no hidden subscription tiers or daily limits. Every utility, including the advanced PDF OCR and Repair PDF, is completely free for personal and commercial document management.
Do I need to install any software to start editing?
No installation required. Our advanced engine runs natively in any modern web browser. Just open the tool, for example Organize PDF, and start dragging pages instantly.
Is there a maximum file size limit for large documents?
Because the processing happens locally on your machine, there are no artificial file size limits. You can process massive files—like those created with Merge PDF—limited only by your device's available RAM.
