Google Chrome. How to run simple JS code?

Question

JavaScript

Good day. There is a JS code that uses only standard built-in JS objects that manipulates SVG images.
It is required to run the code on all pages. Write your Extension for Chrome, read the documentation, understand, there is no time. There is no desire to install an extension (By type: Tampermonkey, etc.).
Issue as an extension, the best option, you can screw PopUp with settings ... BUT!
What other launch options are there?
(Google Chrome: Version 54)
