Citing MDN on this:
Length limitations
Although Mozilla supports data URIs of essentially unlimited length, browsers are not required to support any particular maximum length of data. For example, the Opera 11 browser limits data URIs to around 65000 characters.
长度限制
尽管 Mozilla 支持基本上无限长度的数据 URI，但浏览器不需要支持任何特定的最大数据长度。例如，Opera 11 浏览器将数据 URI 限制为大约 65000 个字符。
And caniuse.com, where you can also look up the support across browsers:
和caniuse.com，您还可以在其中查找跨浏览器的支持：
Support in Internet Explorer 8 is limited to images and linked resources like CSS files, not HTML files. Max URI length in IE8 is 32KB. In IE9 JavaScript files are supported too and the maximum size limit set to 4GB.
Internet Explorer 8 中的支持仅限于图像和链接资源，如 CSS 文件，而不是 HTML 文件。IE8 中的最大 URI 长度为 32KB。在 IE9 中也支持 JavaScript 文件，并且最大大小限制设置为 4GB。
回答by Apurv
Not all browsers support the data URI scheme. IE7 and earlier doesn't support data uri's at all. IE8 has a 32k limit.
并非所有浏览器都支持数据 URI 方案。IE7 及更早版本根本不支持数据 uri。IE8 有 32k 的限制。
