Cache vs. Cookies: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on March 4, 2024
Cache stores copies of web pages and resources to speed up loading; cookies save user data for personalized web experiences.

Key Differences

Cache is used to store local copies of web resources like HTML pages, images, and JavaScript files to reduce loading times and bandwidth usage on subsequent visits. Cookies, in contrast, are small pieces of data stored by a browser that retain user-specific information, such as login details, preferences, and browsing history, to personalize the web experience.
Cache data is stored locally on a user's device and primarily enhances performance by reducing the need to download the same content repeatedly. Cookies, however, can have implications for privacy and tracking, as they store personal information and can be used by websites to track users' browsing activities across the internet.
Cached data often has a set expiration time after which it is refreshed, but users can clear their cache manually. Cookies have varying lifespans, set by the website, and can persist across sessions, but users can also clear cookies or set their browsers to reject them.
Cache stores content like web page layouts and multimedia content, which helps in faster rendering of previously visited pages. Cookies store user-specific data like session tokens, language preferences, and other settings that enable websites to remember users and their preferences.
The cache is generally larger in size and plays a crucial role in the technical performance of web browsing. Cookies are smaller in size and are more about personalizing and enhancing the user experience on individual websites.
