JPEG is a lossy image format, which means each quality level trades some detail for a smaller file. A compression preset refers to a repeatable output setting, and the most useful preset is the one that matches the final use instead of chasing the highest possible percentage.
| Preset | Typical Goal | Tradeoff |
|---|---|---|
| Ultra High | Maximum detail retention | Largest file size |
| Standard | Everyday web and sharing | Balanced quality and size |
| Compact | Fast transfer and previews | Visible compression sooner |
JPG quality refers to the compression setting used when the HEIC image is encoded as a JPEG, which directly affects detail retention and file size.
Different presets use different compression levels, so the same image can produce larger or smaller output files depending on the chosen balance.
No. The best choice is the smallest file that still looks right for your real destination, such as email, archive, or social sharing.
Often yes, because HEIC is a more efficient format, which is why conversion is usually about compatibility rather than raw compression efficiency.
