Convert HEIC to PNG
The efficient photo format iPhones shoot by default: smaller than JPG at similar quality. Lolly reads HEIC/HEIF photos even on browsers that can't open them, using a bundled decoder, so an iPhone photo just works as an image. It's import-only, and it carries no Content Credential.
The go-to lossless image format, with real transparency, so nothing is thrown away and edges over a background stay clean. Great for logos, screenshots and artwork. Lolly tags it with an sRGB profile, can boost it to genuine HDR brightness on capable screens, and embeds provenance and Content Credentials.
大多數同類工具都是上傳型網站：你的檔案會上傳到他們的伺服器，廣告為此買單。Lolly 執行於你的裝置上，因此你的檔案始終留在你身邊。

延續下來的內容: EXIF, XMP - 轉換工具會將描述、作者、版權與拍攝日期移入新檔案。除非你開啟位置資訊,否則會保留在原處;Content Credential 無法複製,因為它與原始位元組綁定。
這種格式保得住 Content Credentials
一切都在你的裝置上完成，關掉 Wi-Fi 照樣能用。
