Does this work offline on iPhone?

Yes — after the first visit Safari caches the tool, so it still runs without a connection.

Are my photos uploaded anywhere?

No. Every conversion runs locally inside Safari on your iPhone; nothing is sent over the network.

HEIC is a newer Apple-driven format without native support on every OS.

Quality is adjustable. The default 92% is visually lossless for most photos.
