Everything happens in your browser, so your images are never uploaded.

Common use cases

Embedding small icons inline in CSS or HTML
Avoiding extra image requests for tiny assets
Storing images in JSON or a database
Previewing and extracting an image from a data URI

How to use the Image to Base64

Copy the data URI, or download the decoded image.

Frequently asked questions

Should I inline large images?

No — data URIs add ~33% size and are best for small assets like icons; large images are better served as files.

Are my images uploaded?

No, conversion happens entirely in your browser.

Which formats are supported?

Any image your browser can read (PNG, JPEG, GIF, WebP, SVG, etc.).
