### Why are custom derivatives needed?

It is common for assets to be uploaded to a DAMS in formats that preserve as much quality as possible. For example, high-resolution uncompressed TIFF images are common for digital photography. Whilst great for print and other media, such formats are simply overkill for most websites. Not only are images likely to be shown at much smaller dimensions in a web browser, but they are also likely to be converted to more web-friendly formats like AVIF or WebP by Wagtail, where the image quality of an uncompressed TIFF is unlikely to shine through.

Over time, unnecessarily large source images will have a compounding impact on website performance. Editors will need to wait longer for Wagtail to download the images from Bynder. And, every time a new rendition is needed, the original must be loaded into memory from wherever it is stored, consuming precious system memory, and blocking system I/O operations for longer while reading from storage.
