How to Use the Data URI Generator

Encode or decode with the Data URI Generator in three steps:

Enter Your Text or Data
Type or paste the text, string, or data you want to encode or decode into the input area. The tool supports standard text input and file upload for batch processing.
Choose the Operation
Select whether you want to "Encode" or "Decode" your data, and optionally configure any algorithm-specific parameters (such as key size or hash type).
Get the Result
The encoded or decoded output appears instantly. Click "Copy" to copy to your clipboard or "Download" to save. All processing is done locally in your browser.

A Data URI embeds file data directly in web pages using the format: data:[MIME type];base64,[encoded data]. It eliminates extra HTTP requests.

Reduces HTTP requests, works offline without external resources, perfect for embedding small files in CSS/HTML.

Base64 encoding increases file size by ~33%. Data URIs can't be cached by the browser (unless inside CSS). Not suitable for large files.

CSS sprite alternatives, small icon embedding, inline images in HTML emails, image data in JSON, self-contained HTML pages.
