Major Risks of Uploading PDFs to Online Servers
When you upload documents to traditional online PDF tools, you're exposing yourself to multiple security risks:
Data Interception
Files can be intercepted during upload if not using proper encryption
Server Breaches
Hackers target servers storing user documents

Client-Side Processing Explained
Client-side processing means that all file operations happen directly in your web browser, without any data being sent to external servers.
How it works:
- Local Loading: You select PDFs from your computer
- Browser Processing: JavaScript and WebAssembly handle the merging
- Local Download: The merged file is created and downloaded to your device
- Zero Upload: No data ever leaves your computer
