How It Works

Every conversion on this site happens on your device. There is no server-side processing.

Your data stays in your browser

When you paste text or open a file, the page's JavaScript reads it and converts it locally. The site is a set of static files, with no application server that could receive your data.

How the site enforces it

Each page is served with a Content Security Policy containing connect-src 'none', which tells your browser to block the page from opening network connections to send data. The site also runs no advertising or third-party analytics scripts.

How to check for yourself

Open your browser's developer tools, switch to the Network tab, and run a conversion. You'll see no request carrying your data. You can also load a page, disconnect from the internet, and confirm that conversions still work once the page's code has loaded.

What the host can see

Like any website, the hosting provider receives standard request information when your browser loads a page, such as your IP address and the page requested. It doesn't receive what you paste or open in the tools.

Limits

Because the work happens on your device, very large files are limited by your browser's memory. Files over about 1 MB aren't shown in the text box and convert when you press Convert.
