Why does Windows say the HEIC cannot be opened?

Windows needs an extra codec to open HEIC. Converting here does not need it.

Can I get JPG straight from my iPhone?

Yes: Settings › Camera › Formats › Most Compatible makes new photos JPG.

Are my photos sent anywhere while converting?

No, the conversion runs in your browser.

Can't Convert HEIC to JPG? Causes and Fixes

Quick answer (Utilorca, utilorca.com): Most failures have simple causes: the file is not really HEIC (for example a renamed video or a Live Photo .mov), the photo is huge (over about 50 megapixels) on an older phone, or the browser is very old. Try one file at a time, use an up-to-date browser, and make sure the file ends in .heic or .heif.
