Optimize for your platform

So funktioniert es

A data URI embeds an image directly into your code as text, so it loads without a separate file request — handy for small icons and self-contained HTML. This encodes it in your browser.

  1. 1
    You drop in an image
    It's read locally with the FileReader API — never uploaded.
  2. 2
    It's Base64-encoded
    The image bytes become a data: URI (data:image/...;base64,…) right in your browser.
  3. 3
    You pick a snippet
    Copy the raw data URI, or ready-made CSS (background-image), HTML (<img>), or Markdown.
  4. 4
    Paste it into your code
    The image now travels inline with your CSS/HTML — no extra file to host.

The image is encoded entirely on your device. Note that Base64 is ~33% larger than the original, so data URIs are best for small images.
