File formats are variants of media files. In order to keep the original file untouched, we use formats to change the content of files and save them separate.
To create a format we use filters that we can apply on the original file. If we want to use a set of different filters, we chain them together.
Enhavo comes already with a set of filters, that covers most of use cases. That includes resizing, compression and preview images out of pdfs and videos. For a full list of all filters check Media
