Why do iPhone photos come in HEIC format?! My family’s Android phones can’t open them. Now I use reaConverter to batch-convert all my HEIC pics to JPEG before sharing. Problem solved, and no quality loss!

My son sends me HEIC photos from his phone, and I can't view them on my old laptop. reaConverter fixed that in two clicks. Now I have JPEGs that open anywhere. It's so easy even I can do it – and I'm not tech‑savvy at all!
