The classic photo format: smaller files by discarding detail your eye barely notices, which makes it ideal for photographs but poor for crisp graphics or text. It's always opaque (no transparency). Lolly tags it sRGB, can write an HDR version for bright displays, and embeds provenance and Content Credentials.
The universal 'looks the same everywhere' document. Lolly writes true page sizes at real physical dimensions (A4, US Letter, and so on), outlines text to paths, and can build multi-page documents. It can lock a PDF with a password (a light 40-bit RC4 lock, or strong AES-256) and carry Content Credentials, and it reads PDFs back in as editable artwork.
大多数同类工具都是上传型网站：你的文件会上传到他们的服务器，广告为此买单。Lolly 运行在你的设备上，因此你的文件始终留在你身边。
