Pixefy helps you spot layout issues instantly and fine-tune designs with live editing tools – right as you build.
It simplifies responsive testing by letting you preview, debug, and edit across multiple screen sizes in one place – no more switching tabs or resizing windows manually.
🚀 Key Features:
✅ Live Responsive Previews – Test across multiple screen sizes side-by-side. Scroll, click, and interact on all screens simultaneously.
✅ Custom Screens & Presets – Create and save your own breakpoints, or use popular device resolutions out of the box.
✅ Screen Management – Rearrange, stack (horizontal/vertical), rotate, or zoom screens globally for a flexible workspace.
✅ Inspect & X-Ray – Inspect styles, edit attributes live, and debug layouts with Visual Box Model, grids, and X-Ray overlays.
✅ CSS Debugging Tools – View/edit computed styles, measure distances between elements, compare two elements, and track all changes in the Activity Tab.
✅ Content Editing – Instantly replace text or images, and check word/character counts directly on the page.
✅ Asset Downloads – Extract SVGs, PNGs, and other assets directly from Inspect Tool tabs.
✅ Screenshots – Capture full pages, visible areas, or selected regions in one click.
✅ User Agent Switching – Simulate different devices, browsers, or bots to see how your site adapts.
✅ Accessibility Tools – Test AA/AAA contrast ratios, extract all colors, and preview vision impairments with blindness simulations.
✅ Utilities – Live Dimension Widget (viewport width/height), copy any value or asset to clipboard, clear cache & refresh Pixefy.
✅ Themes – Switch between light and dark mode instantly.
Pixefy is regularly updated based on user feedback.

- (2025-08-21) David Spector: I installed Pixefy in Chrome, viewed a website, and clicked on the P icon. Nothing happened. I expected something, at least an introductory welcome and instructions.
- (2025-08-12) Alex Gilmore: Great extension, saves time and works perfectly.

- (2024-12-26) Bijwol Shakya: This Chrome extension for responsiveness testing is a must-have for developers and QA engineers alike. It streamlines the process of ensuring a website's adaptability across various devices and screen sizes. While there’s room for a few advanced features, it delivers exceptional value in its current form.
- (2024-11-25) Adel Bakhshi: This is a great extension with a lot of features for web designers. If you are a web designer, I recommend you to use it. This extension will help you to have a great design for different devices. The only problem I saw with this extension is that if the direction of a site is rtl, the layout of the extension elements will also be rtl and I have to convert the value of dir="rtl" to dir="ltr" myself through the Inspector to be able to use it. Thanks
- (2024-11-12) Brian Van Drie: Incredible! This tool is so well designed and it works incredibly well. I am an instant fan. I love the tooltip, inspect element and asset details. It makes identifying issues SO much easier.

- (2024-06-07) Rūta Rylaitė: It's a very helpful tool. I can view now in one window how my photos on the website will look on phones, tablets, and so on. With full-page screenshots that I love. The user interface is intuitive, making it easy to use even for those less familiar with tech. Highly recommended for its efficiency and simplicity.
- (2024-06-03) Károly Jánk: it does not work.... i clicked on extension , show nothing! waste of time!
- (2024-05-31) Edikan Bassey: I just installed and immediately love it. I was looking for an alternative to responsive viewer which i was previously using since they just updated their software and the whole look and feel became rubbish, this is far more superior. Hope in the future the update wont disrupt the design and i wont be asked to pay for nonsense.

- (2024-04-03) Viktorija Paškevičiūtė: A handful extension from a QA perspective. It allows me to use different user agents quickly and go through different device views of web pages.
