There are many great Chrome extensions available for designers, but it can be difficult to know which ones are truly useful. We've tried them all and recommend five must-have extensions that will make your design work easier: ColorZilla for quickly identifying colors on a webpage, WhatFont for finding exact fonts used on websites, Window Resizer for testing website content across different devices, CSS Peeper for inspecting CSS styles, and Jam for catching design bugs and sending them to developers with all the necessary context. These extensions are essential tools for designers working with Chrome and can also benefit developers.
