Data URI Guide

Data URIs allow you to embed small files directly in HTML, CSS, or JavaScript as inline data. They follow the format: data:[mime-type];base64,[encoded-data]. This eliminates the need for separate HTTP requests, which can improve page load performance for small resources.

What is a data URI?

A data URI is a scheme that allows embedding small files directly in HTML/CSS using Base64 encoding. It follows the format: data:[mime-type];base64,[encoded-data].

When should I use data URIs?

Data URIs are best for small files (< 10KB) like icons, small images, or fonts. They reduce HTTP requests but increase file size by ~33% due to Base64 encoding.

What file types are supported?

Any file type is supported. The MIME type is automatically detected from the file extension.

Is this tool free?

Yes, completely free with no signup or limits.
