What is Image → Base64?
Convert images to Base64 data URIs for embedding directly in HTML/CSS, or decode data URIs back to images.
How it works
We use the browser's FileReader API to encode images to Base64 and provide ready-to-paste HTML/CSS snippets.
- Upload. Upload an image to encode
- Copy. Copy the Base64 string, HTML, or CSS snippet.
Examples
Inline icon
Embed a small icon as a data URI to avoid an extra HTTP request.
