HTML to Base64

Comments: 21 | Rating: 4.1/5

This online converter allows you to encode HTML to Base64. Although this is an unusual use of the Base64, some developers use it and hope that this converter does exactly what you need. If you are looking for examples of how to embed Base64 encoded data into web pages, please check the following pages: Data URI and HTML.

How to convert HTML to Base64

  1. Type or paste your HTML into the “HTML” field.
  2. If necessary, select the desired output format.
  3. Press the “Encode HTML to Base64” button.
  4. Download or copy the result from the “Base64” field.

Output formats

If you do not know what output format you need, check the following examples to see how will look the result of the same Base64-encoded HTML formatted in each of the available formats:

• Plain text:
V2VsY29tZSB0byA8Yj5iYXNlNjQuZ3VydTwvYj4h
• Data URI:
data:text/html;base64,V2VsY29tZSB0byA8Yj5iYXNlNjQuZ3VydTwvYj4h
• HTML Hyperlink:
<a href="data:text/html;base64,V2VsY29tZSB0byA8Yj5iYXNlNjQuZ3VydTwvYj4h"></a>
• HTML Iframe:
<iframe src="data:text/html;base64,V2VsY29tZSB0byA8Yj5iYXNlNjQuZ3VydTwvYj4h">
  The “iframe” tag is not supported by your browser.
</iframe>
• JavaScript Popup:
window.onclick = function () {
  this.open("data:text/html;base64,V2VsY29tZSB0byA8Yj5iYXNlNjQuZ3VydTwvYj4h");
};

If I missed an important output format for Base64-encoded HTML strings, please let me know — I would love to implement it.

  • Kingnero,
    I just encoded my html file now but I couldn't view it on my browser. I actually did this:


    <script src="data:text/html;base64,PGh0bWw+DQo8aGVhZD4NCjx0aXRsZT5BZG9iZSBEb2N1bWVudCB8I"></script>


    and save the file but i couldn't view it in browser

      The script element is used to "include" JavaScript code, while for your case you have to use iframe.
