How Local Processing Works

Unlike traditional online converters that upload your files to a server, ConvertUnlimited works entirely inside your web browser. Selected file contents are processed locally in your browser.

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

✅ browser-native local processing (file contents are processed locally in your browser)
✅ No file-transfer wait after the page loads
✅ 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)
❌ server-side exposure risks

Privacy behavior

Selected file contents are processed locally in your browser for supported workflows. This privacy build does not intentionally load ads, analytics, remote fonts, or third-party runtime scripts.

FAQ

Are my files safe?

Yes. Since your file contents are not intentionally uploaded by supported tools, 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). After the static page is loaded, supported processing flows run locally in the browser.
