Frequently Asked Questions
Base64 is a binary-to-text encoding scheme that represents binary data (like images) as ASCII text using 64 characters. This allows binary files to be embedded directly in text-based formats like HTML, CSS, XML, and JSON without requiring a separate file.
A Data URI is a URI scheme that embeds data inline. For images it looks like:
data:image/png;base64,iVBOR.... You can use it directly in an HTML <img src="..."> or CSS background-image: url("...") without any external file.Base64 encoding increases file size by approximately 33%. For example, a 100KB image becomes ~133KB as Base64. This is the trade-off for embedding images inline. For large images, use external files with a URL reference instead.
All common browser-supported image formats work: PNG, JPEG, GIF, WebP, SVG, BMP, ICO, and AVIF. The MIME type is automatically detected from the file and included in the Data URI prefix.
