Your Files Never Leave Your Device
MixConvert is fundamentally different from other file converters. We process everything locally in your browser — there's no upload, no server, and no way for us to ever see your files.
How It Works
1. You Select Files
When you choose files, they're read directly by your browser. They never travel over the internet.
2. WebAssembly Converts
We use FFmpeg compiled to WebAssembly — the same powerful tool professionals use, running locally on your device.
3. Works Offline
After the page loads, you can disconnect from the internet and still convert files. Proof that nothing is uploaded.

Verify It Yourself
Don't just take our word for it. Here's how to prove your files stay local:

- Go to the Network tab
- Convert any file on MixConvert
- Watch the network activity — you'll see zero file uploads
Frequently Asked Questions
Is MixConvert HIPAA/GDPR compliant?
Since no data ever leaves your device, there's no data transfer to regulate. Your files are processed entirely client-side, which inherently satisfies data privacy requirements. Consult your compliance officer for your specific use case.
What happens to my files after conversion?
Your original and converted files exist only in your browser's memory. When you close the tab or refresh the page, they're gone. We have no servers that could store them even if we wanted to.
Is this really free? What's the catch?
Yes, it's genuinely free with no hidden fees. Because everything runs in your browser, we don't have expensive server costs for processing files. We may show non-intrusive ads to support development.
