Use data URI scheme to embed images in webpages

 

Data URI scheme allows us to include data in a webpage using inline-code, which can be used in Html, CSS, and Javascript.

 

Data URI scheme is often used to embed images into webpages. It is used as follows:

 

The data URI scheme format is as follows:

Data: [<MIME-type>] [; base64], <data>

 

The format is relatively simple. We can see that the above img is a jpg image encoded with base64.
Embed this img into this page, as shown below:

 

In addition to base64 encoding, you can also use hexadecimal URL encoding in the form of % xx, as shown below:

Generating image data

According to the above format, we can write a small program to generate, but we don't need to be so troublesome. Many websites provide this (free) service.

The following are some examples:

1. http://dataurl.sveinbjorn.org/dataurlmaker

Provides preview for convenient copying.

 

2. http://websemantics.co.uk/online_tools/image_to_data_uri_convertor/

Provides preview and generates the URI data of the corresponding CSS.

 

3. http://software.hixie.ch/utilities/cgi/data/data

Tip: generation is not limited to image data. You can use three methods (see steps 1, 2, and 3) to specify the encoding method, but the interface is unfriendly.
