HEICをJPGへ：検索が多い理由
iPhone写真の互換性と、手軽に共有するための変換。
HEIC (or HEIF) is Apple’s efficient photo format on iPhone and iPad. It saves space compared to JPEG, but many websites, email attachments, and older PCs expect JPG instead.
Converting HEIC to JPG is one of the most common “phone to web” workflows: you keep a widely compatible image without asking recipients to install codecs.
Before converting, check whether you still need transparency or very wide color—JPG does not support transparency. For graphics with alpha, PNG or WebP may be better.
Use Panyas Converter’s HEIC to JPG tool in the browser: upload, convert, download. Delete local copies of sensitive photos after you finish.
