Generally yes. HEIC and HEVC are the high-efficiency formats Apple devices use by default; they typically store a photo or video at similar quality in a noticeably smaller file than JPEG or H.264.
Converting your existing HEIC photos to JPEG will usually make them bigger, so only do it when an app or person needs JPEG. Most current software on Mac and Windows opens HEIC and HEVC.
