PNG or JPG — which should I use for iPhone photos?

PNG for editing, print, or any further processing — bit-faithful decode, no JPEG artifacts. JPG for sharing, email, social, web upload — much smaller files.

How large will the PNG be?

Substantially larger than the HEIC — typically 5–10× larger because PNG is uncompressed for photographic content. That's the cost of losslessness.

Will EXIF orientation be correct?

Yes — the HEIC's EXIF orientation tag is read and the pixels are rotated before encoding. Portrait shots taken sideways will come out upright.

Why can't Windows or Android open HEIC natively?

HEIC requires the HEIF codec, which is paid on Windows (Microsoft Store) and missing on many Android devices. PNG is universal.

PNG 是 HEIC 的无损输出路径：忠实于解码后的像素，无 JPEG 伪影，支持透明。输出文件会比原始HEIC大得多，因为HEIC被高度压缩，而PNG没有——这是预期中的。当照片即将被编辑、修饰或发送打印时，选择PNG。当目标是电子邮件、网页上传或社交分享时，选择JPG（HEIC转JPG工具），这些地方需要尺寸。
