FAQ

What is a data URI?
A data URI (data URL) embeds file content directly in a URL string, encoded as Base64. For images, the format is data:image/png;base64,<encoded-data>. This lets you embed images directly in HTML src attributes or CSS background-image values without a separate file request.
When should I use data URIs for images?
Data URIs are best for small images (icons, logos) where avoiding an extra HTTP request outweighs the overhead of inline encoding. For large images they increase HTML/CSS file size significantly and can hurt performance.
What is the typical size increase from Base64 encoding?
Base64 encoding increases file size by approximately 33%. For example, a 10 KB image becomes roughly 13–14 KB as a data URI string.

Upload any image (PNG, JPEG, WebP, SVG, GIF) and convert it to a Base64-encoded data URI in the format data:image/png;base64,.... The full URI is displayed in a textarea with a one-click copy button. The tool also shows the character length of the resulting string so you can assess suitability for inline embedding in HTML or CSS.
