Frequently Asked Questions
A Data URI is a scheme that allows you to embed data (like images or fonts) directly into HTML or CSS files instead of referencing an external file. It starts with "data:" followed by the MIME type and the base64-encoded data.
Data URIs are great for small icons, decorative images, or fonts to reduce the number of HTTP requests. However, they increase the size of your HTML/CSS files by about 33% compared to the original binary file, so avoid them for large assets.
While the technical limit varies by browser, most modern browsers support Data URIs up to several megabytes. However, very long URIs can impact performance and initial page load times.
