How Local Processing Works
Unlike traditional online converters that upload your files to a server, ConvertUnlimited works entirely inside your web browser. Your files never leave your device.
The Magic of Browser-Native Processing
We use modern web technologies like the HTML5 Canvas API and WebAssembly (WASM) to decode and encode your images and documents locally. When you drop a file, your browser's own engine does the heavy lifting.
Why This is Better for You
LOCAL-FIRST
- ✅ 100% Private (No one else sees your files)
- ✅ No upload/download waiting time
- ✅ Work offline once the page is loaded
- ❌ Limited by your device's RAM/CPU
- ❌ Extremely large files (2GB+) may struggle
SERVER-BASED
- ✅ Can handle massive enterprise-scale files
- ❌ Files are uploaded to someone else's server
- ❌ Slower (upload/download required)
- ❌ Privacy risks
Our Privacy Promise
ConvertUnlimited is designed to be zero-knowledge. We don't have a backend that stores your data. We don't have accounts. We don't track your content. The code you see on the screen is the code that runs on your machine.
FAQ
Are my files safe?
Yes. Since your files are never uploaded, they are as safe as they are on your own computer.
Does this use my internet data?
Only to load the initial website (a few KB). The actual file processing uses zero data because it happens offline on your device.
