Introduction to Assets

From this article, you’ll learn what assets are and which asset types are available in Prepr.

What are assets?

Assets are media files such as images, video, audio, and other digital files you can use on your web pages to enrich content.

With the growing demands of an internet business, brands have to do more to stand out and meet the rising expectations of potential customers. Rich content has a crucial role in attracting and keeping your audience.

Prepr allows you to easily create content pages filled with rich media assets. Let's look at it in detail.

Assets in Prepr

An Asset in Prepr is a media file, such as an image, audio, video, live stream, or another file type, that lives in one organized storage — the Media Library. You only need to upload digital assets to Prepr once, and you can reuse them on multiple web pages.

Prepr automatically deploys and serves all media assets over a high-performing Content delivery network (CDN). A CDN stores a cached version of content and puts it in many places simultaneously. This improves page load speed and accelerates content delivery.

Prepr supports the most popular image formats and provides automatic image optimization with WebP encoding technology. The WebP format makes your web pages load faster, frees up storage space, and guarantees high image quality.

The following table lists the asset types in Prepr and their supported media formats.

Asset typeDescriptionSupported formats
ImageImage files such as photos.JPG, JPEG, PNG, BMP, and more.

Note: WebP, SVG and GIF graphics are supported through the File asset in Prepr.
VideoVideo files and live video streams.MOV, M4V, MPG, MP4, and more.
AudioAudio files.MP3, M4A, WAV, and more.
FileArchives, documents, and vector images.ZIP, PDF, XLSX, DOCX, SVG, GIF and WebP.


There’s a wide range of image options in the Prepr Editor interface and through the API. For example, image presets for different device types, cropping, captions, and more.

Graphic files such as WebP, SVG and GIF cannot be processed through the image pipeline. To work with WebP, SVG and GIF graphics, use the File asset in Prepr.

Video and Audio

You can enrich your web pages with audio and video content or broadcast live video streams thanks to the Prepr and Mux Video integration. This integration gives you the benefits of seamless multi-channel content delivery and cutting-edge video processing technologies.

Mux Video accepts most modern video formats and codecs. And you get automatic video transcoding, audio normalization, and high-quality live streaming with the HLS (HTTP Live Streaming) protocol out of the box.

Prepr uploads your media files to Mux automatically, so you do not need to have a Mux account yourself. Follow our step-by-step guides to post audio and video content or stream your live video in a web application.


With Prepr, you can add different file types to your web application, such as PDF, ZIP, and more. You can also use the File asset to work with SVG and GIF graphics in Prepr. Find more details in the Files guideline.
