Privacy Policy

Your files

Your files are processed entirely in your browser, using JavaScript and WebAssembly, and are never transmitted to any server. When you drop or select a file, it's read directly from your device's disk into memory, decoded and re-encoded locally in a background worker thread, and offered back to you as a download. The bytes never travel over the network, because there's no server anywhere in that path to send them to.

This is a verifiable claim, not a promise you have to take on faith. Open your browser's developer tools (in most browsers: right-click the page → "Inspect" → the "Network" tab), convert a file, and watch the network activity yourself. You'll see no request carrying your file data leave the page. There is no upload step, no server-side processing, and no copy of your file is ever stored anywhere by this site.

This guarantee is not specific to the HEIC converters. It applies to every tool on this site, current and future: nothing is ever uploaded, on any of them.

Analytics and cookies

This site uses Google Analytics (GA4) to understand traffic: which pages get visited, roughly what device and browser you're using, an approximate location derived from your IP address, how long a session lasts, and general patterns like that. It also sets a cookie to tell one visit apart from another.

GA4 runs inside a separate web worker rather than the main thread, using a tool called Partytown, so it never competes with page load or with the conversion tools themselves for your device's processing power.

GA4 never sees your files. It only observes page visits and navigation, and has no access to what happens inside the conversion tool itself: no file name, no file content, and no converted output ever reaches it. That part of this site still runs entirely on your device, with nothing uploaded, exactly as described above.

Hosting

This site is served as static files with no backend server or database, hosted on Hostinger. Standard web server logs (such as IP address and request time) may be recorded by Hostinger for security and operational purposes, independent of anything this site's code does.
