Umbraco File Upload Preview

What is it?

File Upload Previews are custom web components that render previews for specific file types during upload in Umbraco. They allow you to create visual representations for files based on their MIME types, such as displaying thumbnails for images, waveforms for audio, or custom icons for specific file formats.
