What Is Data URI to UTF-8 Converter?

Our Data URI to UTF-8 Converter is a free online tool that decodes data URIs back into readable UTF-8 text. Data URIs are a way to embed data directly into web pages using the data:[mime][;charset][;base64],data format. This tool extracts the embedded content and displays it as human-readable text.

How to Use the Data URI to UTF-8 Converter

  1. Paste a Data URI: Enter or paste your data URI in the input area.
  2. Automatic Decoding: The tool instantly decodes both base64 and URL-encoded data URIs.
  3. View Results: The decoded UTF-8 text appears alongside metadata about the data URI.

Understanding Data URIs

A data URI has the format data:[<mime type>][;charset=<charset>][;base64],<data>. The tool parses each part:

  • MIME Type: Indicates the type of data (text/plain, text/html, etc.)
  • Charset: Specifies the character encoding (UTF-8 by default)
  • Encoding: Data can be base64-encoded or URL-encoded

For example, the data URI data:text/plain;base64,SGVsbG8sIFdvcmxkIQ== decodes to Hello, World!

Frequently Asked Questions

What formats of data URIs does this tool support?

The tool supports both base64-encoded data URIs (data:...;base64,...) and URL-encoded data URIs (data:...,...). It supports any MIME type and charset.

Can I decode binary data URIs like images?

This tool is designed for text-based data URIs. Binary data URIs (like images) will be decoded to text, but the result may appear as garbled characters since the binary data isn't human-readable text.

What information does the metadata section show?

The metadata displays the MIME type, encoding method (base64 or URL), charset, original data length, and decoded text length — giving you full insight into the data URI structure.

Is my data processed server-side?

No, all decoding is performed locally in your browser using JavaScript. Your data URIs remain private and are never transmitted to any server.
