Como funciona

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