My transparent PNG came out with a black background.

JPEG has no transparency, so every transparent pixel must become something. Set the background colour before converting — white is usually what you want.

Which format should I pick?

WebP for the web: same quality, noticeably smaller. JPEG for photos that must open anywhere. PNG when you need transparency or crisp text and screenshots.

Can it convert iPhone HEIC photos?

Yes — HEIC to JPG or PNG is the common case, and the reason most people arrive here. The conversion happens in your browser.

Which format should I choose?

JPG for photographs, PNG when you need transparency or crisp text, WebP when you want both at a smaller size and the recipient is a browser.
