关于 Base64 图片你需要了解的一切
什么是 Base64 Data URI？
A Data URI is a string that embeds the content of a file (an image in this case) directly into the code, with no need for an external file. It has the format data:image/png;base64,XXXX where XXXX is the Base64-encoded image.
为什么编码后的图片比原图大？
Base64 encoding represents every 3 bytes of binary data with 4 text characters, so it increases the size by about 33%. That is why inlining in Base64 is only worthwhile for small images (icons, logos): it reduces HTTP requests, but for large images a normal file is better.
