Designers constantly need to check what color, font or spacing another site is using, or preview how a layout behaves at different screen sizes. Browser extensions put these checks one click away, saving the time it takes to open developer tools or a separate app just to answer a quick visual question.

Picking colors and identifying fonts on any page

A color picker extension like ColorZilla lets you click anywhere on a page to get the exact hex or RGB value, and often includes a gradient generator. Font-identifying tools work similarly: hover over any text and see its font family, size and weight, which is faster than inspecting CSS in dev tools for a quick check.

Testing responsive and UX design

Extensions built for responsive design let you preview a page at common device widths without resizing your browser window manually. UX-focused tools can overlay grids, measure spacing between elements, or simulate color blindness so designers can check accessibility before shipping a layout.

Choosing tools that fit a designer's workflow

Look for extensions that work directly on the live page rather than requiring a screenshot upload first. Free tools like ColorZilla and WhatFont cover the most common daily checks, while paid or freemium options add features like exporting palettes or saving font libraries across projects.

Best Chrome extensions for designers: FAQs

What is the best Chrome extension for designers?

ColorZilla is our top pick because it is free and lets you pick the exact color of any pixel on a webpage. It's a daily tool for matching brand colors or checking what colors a site actually uses.

How do I find the font used on a website?

Install WhatFont, hover over any text on a page, and it shows the font family, size and weight instantly. It works on live pages without needing to open developer tools.

Is ColorZilla free to use?

Yes, ColorZilla is free. It includes an eyedropper color picker, a page color analyzer and a gradient generator, all usable without creating an account.

What Chrome extensions do UI/UX designers use most?

UI/UX designers commonly rely on a color picker like ColorZilla and a font identifier like WhatFont for daily inspection tasks, alongside dedicated tools for accessibility checks and responsive layout previews.

Can I test responsive web design with a Chrome extension?

Yes. Responsive design extensions let you preview a page at common device widths, such as phone and tablet sizes, inside one browser tab instead of resizing the window or using separate devices.

Do design extensions work without an internet connection?

Most, including ColorZilla and WhatFont, work on any page already loaded in your browser, so they function offline once the page itself is loaded. They don't need a live server connection to inspect colors or fonts.

Are design Chrome extensions safe for client work?

Tools that only read the page you're viewing, like a color picker or font identifier, pose minimal risk since they don't need to send your data anywhere. Check the permissions before installing any extension on a machine with client files.

What's the difference between ColorZilla and browser dev tools?

Browser dev tools require opening a separate panel and inspecting elements manually. ColorZilla adds a one-click eyedropper directly in the toolbar, which is faster for quick color checks during design review.

Can designers use these extensions in Edge or Brave?

Yes. ColorZilla, WhatFont and most Chrome Web Store design tools also work in Chromium-based browsers like Microsoft Edge and Brave, since they share the same extension platform.

Is there a Chrome extension to check color contrast for accessibility?

Some design and accessibility-focused extensions can check contrast ratios between text and background colors against WCAG guidelines, helping designers catch readability issues before a page ships.

Do I need multiple design extensions or just one?

Most designers combine a color picker like ColorZilla with a font identifier like WhatFont, since each solves a different, narrow task. Installing both covers the majority of daily design inspection needs.
