Data protocol URL size limitations

Question

Is there any size limitation for \"data:\" URL scheme values? I\'m interested in limitations in popular web browsers. In other words, how long can data:image/jpg;base6

Answer 1

Note: There are some additional restrictions in IE. For iframe is a limit of 4 kb.

In IE9, the 32kb limit for DataURIs was removed, although for security reasons their use remains limited to certain contexts (specifically, scenarios that create a security context, like IFRAMES, are forbidden)
