What is Uppy?
With Uppy, you get a lightweight, modular, plugin-based architecture that is easy to maintain. By allowing resumable file uploads and file recovery, it is able to handle network and browser crashes or misclicks.
With an open-source implementation and built with accessibility in mind, Uppy is a truly modern tool.
Uppy JXL support
Since the 29th of July 2020, Uppy supports handling of AVIF files. Even though the file upload has worked, it supports fully displaying image thumbnails as well.
