Why I Built ITKB.app to be 100% Client-Side

As a tech creator at "IT Kang Baan" (ไอทีข้างบ้าน), I’ve seen countless users worry about their sensitive data when using online tools. That’s why I developed ITKB.app using Client-side Processing technology. My philosophy is simple: your files should never leave your computer. I believe great tools should be **free, accessible, and above all, respect your privacy.**

The Power of Local Processing (WebAssembly)

I utilize WebAssembly (WASM) to harness your device's own power. Whether you are separating vocals from music, compressing videos, or unlocking Excel files, everything happens right in your browser. No upload queues, no server-side storage, and zero risk of anyone else seeing your files.

Data Efficient (Only loads the page once)

Built for Productivity & Peace of Mind

Whether you need to edit videos online, scan QR codes from images, or manage JSON data, I’ve built these tools to be minimalist, fast, and secure. ITKB is perfect for office workers, students, and developers who need reliable tools they can trust. No strings attached, just pure utility.
