What is the difference between a pixel and a cookie?

Cookies are small files that are stored on user devices and are used to ensure basic website functionality, remember settings on a website (for example, language), enhance user experience, and advertise relevant content. As for tracking pixels, they’re tiny and transparent images embedded in the HTML code of your website or email. They’re used to monitor user behavior related to conversions or traffic.

Here are the main differences between a pixel and a cookie:

• Purpose. A cookie is used for collecting personal information about the user and profiling them for marketing reasons and user experience, while a tracking pixel monitors user behavior only for marketing purposes.
• Storage. Cookies are placed on a user’s device, while pixels are embedded in content and can follow users across devices.
• Management. Cookies can be managed using a cookie consent banner or browser, while pixels cannot be disabled by users.
