ODP and JPG explained
ODP is the OpenDocument presentation format used by LibreOffice Impress, the open-standard counterpart to PPTX.
JPEG is a lossy image format designed for photographs. It works by discarding detail the human eye is least likely to notice, particularly in colour and in smooth gradients, which is why it compresses photos far better than it compresses text or line art.
- Where ODP files come from
- LibreOffice Impress and open-standards environments.
- Where JPG is used
- Digital cameras, phone screenshots on Android, and essentially every photo on the pre-2015 web.
