No. Your PNG files are read and converted entirely inside your browser using JavaScript. They never leave your device or get sent to any server.
Can I convert multiple PNG files at once?
Yes. You can add several files and convert them in one batch. Each downloaded file keeps its original name with the new .webp extension.
