When to Use Base64 Encoded Images
Encoding images as Base64 Data URIs is a common technique in frontend development to embed small icons, SVG logos, and background patterns directly inside HTML documents and CSS stylesheets.
By embedding the asset directly in the document, you eliminate an extra HTTP network request, preventing visual flicker during page loads. However, because Base64 increases file size by approximately 33%, this technique is best suited for small images (under 10 KB to 20 KB) rather than large hero photos.
