An e-catalog is an electronic document that presents a collection or catalog of products or services in a digital format. Similar to traditional catalogs, e-catalogs provide an overview of products or services to potential customers, but they do so in a digital medium. They are typically found on websites or other digital platforms.

E-catalogs often incorporate interactive features, allowing users to search, filter, zoom in, and examine details of products. Additionally, many e-catalogs enable direct purchasing of products or services through links and clickable elements.

This digital format allows the presentation of detailed descriptions, images, and even videos of products or services to potential customers. It also facilitates easy navigation between products and quick access to the information users are looking for.

E-catalogs serve as an effective tool not only for customers to explore a range of products and understand the diversity a brand offers but also for brands to introduce their products or services to a wider audience and support their marketing strategies. Furthermore, e-catalogs stand out as an environmentally friendly option as they reduce paper consumption and are easily shareable in digital formats.
