This article will explain in detail how to use data URI scheme to embed pictures in the web page. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Data URI scheme allows us to use inline (inline-code) to include data in web pages, which can be used in Html, CSS, Javascript, etc.

Data URI scheme is often used to embed pictures into web pages, using the following:

The data URI scheme format is as follows:

Data: [] [; base64]

This format is relatively simple, and if you compare it, you can see that the img above is a jpg image encoded in base64.

Embed this img into this page and display it as follows:

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

_ fcksavedurl= "" data:image/jpeg,%FF%D8%FF%E0JFIFq/* omitted a lot of data here * /% F7*q%D6Q%EDt%F6%EE%7F%FF%D9 "/ >" _ fcksavedurl= "" data:image/jpeg,%FF%D8%FF%E0JFIFq/* omitted many data here * /% F7*q%D6Q%EDt%F6%EE%7F%FF%D9 "/ >"

Generate picture data

According to the above format, we can write a Mini Program to generate, but we do not need to go to so much trouble, there are many websites offering this (free) service.

Here are a few:

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

Provide preview, easy to copy.

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

Provide a preview, but also generate the corresponding CSS URI data.

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

Tip: generation is not limited to image data, you can use three ways (see figure 1, 2, 3 below), you can specify the encoding method, but the interface is not friendly.
