# To Case Insensitive Regex

Converts a case-sensitive regex string into a case-insensitive regex string in case the i flag is unavailable to you. For example, `Mozilla/[0-9].[0-9] .*` becomes `[mM][oO][zZ][iI][lL][lL][aA]/[0-9].[0-9] .*`. To Case Insensitive Regex lives in the **Utils** category of the `fx` menu.
