Preset

Select a preset, or omit to use the default preset. A preset is a collection of settings which determines nearly everything about JPT's output, from the image formats used to the exact format your final HTML will take. Think of it like a recipe or a blueprint; JPT will take the information provided in the liquid tag, combine it with the settings written in the preset, and use it to craft your images and markup.

If the preset is omitted then default settings will be used, in the simplest case resulting in an <img> tag containing a srcset pointing to your newly generated images. You are free to override the default preset and define your own settings, giving full flexibility in what JPT will create.
