Small, reduced-size images serving as previews for larger images or videos.


Thumbnails are small versions of images or video frames that represent larger versions of the same files. They are designed to be significantly smaller in size, which speeds up the loading times of web pages on which they are displayed. Thumbnails provide a preview of the full-size content, allowing users to decide if they want to view or open the larger version. They are a fundamental element in web design and user interfaces, enhancing user experience by efficient content navigation.

Usage and Context

Thumbnails are widely used across the internet, especially on websites that host large amounts of multimedia content like images and videos. Examples include photo galleries, e-commerce product listings, video sharing platforms, and social media sites. They allow for a more organized display of multiple items, making it easier for users to browse through content without being overwhelmed.

Thumbnails also play a crucial role in reducing bandwidth and improving the loading times of websites, as they are considerably smaller in size compared to their full-sized counterparts. On mobile devices, where screen real estate and data usage are limited, thumbnails are particularly important.
