Frequently asked questions
What is a Base64 data URI?
It's the image encoded as text, so you can embed it directly in HTML or CSS without a separate file request.
When should I inline images this way?
For tiny icons or one-off images, to save an HTTP request. Large images bloat your HTML and are better kept as files.
Does it give me ready snippets?
Yes — it outputs the data URI plus copy-paste img and CSS background examples.
