What happens to my file?
Your file never leaves your device.
Step by step
You choose a file
Your browser reads it from your device into its own memory. Nothing is sent anywhere.
Your browser converts it
The converter is code that came with the page. It runs in your browser, on your device's own processor.
You download the result
The new file is saved straight from your browser's memory to your device.
You close the page
Your browser clears the file from its memory. We never had a copy.
Check it yourself
Open any converter and wait until it says it's ready offline. Then switch off Wi-Fi and mobile data, or turn on flight mode, and convert a file. It still works, because nothing needs to go over the internet.
Watch the network
On a computer, open your browser's developer tools and choose the Network tab. It lists every request the page makes. Then convert a file: no request carries your file. What you may see there is listed below.
What this site does send
Your browser does talk to the internet while you use this site. This is all of it, so nothing in the Network tab comes as a surprise:
The page and the converter's code are fetched when you open a page.
- Who gets it
- Cloudflare, which hosts this site
- What they see
- Your internet address and browser type, like the host of every website.
The FFmpeg program (31 MB) is fetched the first time you choose a file on four converters: AVI to MP4, WMV to MP4, MP4 to AVI and WMA to MP3.
- Who gets it
- jsDelivr, a public service for open-source code
- What they see
- Your internet address and browser type.
Never in any of these: your file, its name or its size.
