About this tool

About Data URI Generator

The Data URI Generator turns a dropped image into a complete data: URI plus copy-ready HTML and CSS snippets. It is for developers who want the URI and the markup to use it in one place.

A data URI is more useful with the surrounding markup ready to paste. Generating both locally saves steps and keeps the image private.

  2. The complete data URI is generated.

FAQ

Common questions

A data URI embeds a file inline using the data:[mime];base64, scheme, so a small asset can live directly in your HTML or CSS without a separate request.
Inlining suits small, frequently used assets such as icons. For larger images a normal file request is usually better for caching and performance.
Any image format the browser reads — PNG, JPG, WebP, GIF, SVG, and more. The correct MIME type is detected automatically.
No. The data URI is built locally from the file you choose; nothing leaves your browser.
Private by design

This runs entirely in your browser

No file or text you enter here is uploaded. Encoding and decoding happen on your device using native browser APIs — close the tab and nothing remains on a server.
