What is a Data URI?

A Data URI (Uniform Resource Identifier) is a scheme that allows you to embed small files directly into HTML, CSS, or JavaScript as a string of text. The format is `data:[][;base64],`. This eliminates the need for separate HTTP requests, improving page load speed for small assets. Common uses: embedding icons, images, fonts, or even entire documents. Our tool converts any file to a data URI instantly. Files are processed locally – no uploads, complete privacy.

📌 How to Use
