Convert files on your own machine. Nothing is uploaded.
Every tool runs in the browser tab you are reading this in. Your photos, contracts and tokens are read from disk, processed on your CPU, and handed straight back.

Why trust it
check it yourselfTen seconds to verify
Open your browser's network tab and convert a file. You will see this page load, and a small page-view count go out — and not your file. Then switch your Wi-Fi off and convert another one.
The whole trick
Browsers gained the ability to read files, decode images and run compiled code years ago. Many online converters do the work on a server, which means your file is uploaded first.
This one does the work where the file already is. The HEIC decoder is libheif compiled to WebAssembly, about 1.5 MB, downloaded once and then cached. After that the page keeps working with the network switched off.

The older converter sites are being folded into this one, so there is one set of tools to maintain instead of four.
