Why Client-Side Processing Matters: Privacy in the Age of Cloud
Understanding the importance of client-side file processing and why keeping your data on your device is crucial for privacy and security.
Why Client-Side Processing Matters: Privacy in the Age of Cloud
In an era where data breaches make headlines weekly, understanding where and how your files are processed has never been more important. Let's explore why client-side processing is the future of online tools.
What is Client-Side Processing?
Client-side processing means your files are processed directly in your web browser, on your device. The files never leave your computer and aren't uploaded to any server.
Traditional (Server-Side) Approach:
- You upload your file
- Server receives and stores it
- Server processes the file
- You download the result
- Server (maybe) deletes your file
Client-Side Approach:
- You select your file
- Your browser processes it locally
- You download the result
- Nothing was ever uploaded
